From Storage to Road: 5 Vital Steps to Prepare Your Austin Healey for Spring Driving

After a long winter lay-up, your classic Austin Healey deserves some TLC (tender loving care, not the TV channel!) before roaring back onto the road. Here, we will guide you through the essential maintenance tasks to get your Healey in tip-top shape after winter storage. Don’t worry if you’re not mechanically inclined – each step is straightforward and aimed at owners with little mechanical experience.

Grab a cuppa, roll up your sleeves, and let’s prepare your Healey for a trouble-free spring drive, all in a confident, trendsetting style that even your local car club will admire.

 
 
Uprated 12-volt battery for Austin Healey

1. Recharge or Replace the Battery and Check Electrics

Winter hibernation can be hard on your Austin Healey’s battery. First, reconnect the battery (if you disconnected it for storage) and inspect the terminals for any corrosion (a white or green crust). Clean the terminals with a battery terminal brush or some baking soda solution if needed, to ensure a good electrical connection.


Next, check the battery’s charge – a healthy 12-volt battery should read about 12.6V with a multimeter. If you don’t have a multimeter, simply turn the key: dim dash lights or sluggish cranking are signs the battery may need a boost. Charge the battery slowly with a suitable charger, or, if it’s past its prime, consider a replacement. We offer classic-style uprated batteries such as our 6-volt batteries for the BN1, BN2, BN6, and BN7 models, and a 12-volt battery for BN4, BT7, BJ7 and BJ8 models. These fit the period while delivering improved output.


While you’re at it, test all the electrics: headlights, indicators, brake lights, and horn – you want to be seen and heard on the road! If any bulbs are out, now’s the time to replace them. Also ensure the fuses haven’t corroded in their holders (a quick wiggle can clean the contacts).


A confident Healey owner checks these little details to avoid roadside fiddling later.

Benefits

  • Reliable starting so you’re not left stranded with a click instead of an engine rumble.
  • Bright lights and functioning electrics for safe driving and navigation.
  • Prolonged battery life by ensuring connections are clean and the charge is maintained (next winter, consider a trickle charger to keep the battery healthy).

Summary:

Make sure your battery and all electrical components (lights, horn, fuses) are up to scratch, so your Healey starts and stays lit on the roads.

2. Change Engine Oil and Filter

An oil change is one of the most important spring maintenance tasks for any classic car. Engine oil can accumulate moisture and contaminants during long storage, which you definitely don’t want circulating in your treasured Healey’s engine.


Start by draining the old oil when the engine is slightly warm (if possible) so it flows out easily – but since the car’s been stored, run it just for a minute or two at most, or not at all if the oil looks very old. Remove and replace the oil filter as well. Many Austin Healeys use an element-style oil filter; make sure to fit a new one, which are inexpensive and readily available. If your Healey has been upgraded with a spin-on oil filter conversion, changing the filter will be even easier – if not, this might be a good upgrade to consider for the future.


Once the new filter is in, refill the engine with the correct grade of fresh classic car oil (for example, a 20W50 classic motor oil is commonly used in big Healeys). Be sure to check your engine oil level with the dipstick after filling and again after your first drive, topping up if necessary.


With fresh oil, your Healey’s engine will thank you with smoother running. Do not skip this step – consider it an early springtime “detox” for your car’s engine.

Benefits

  • Improved engine longevity: Fresh oil provides better lubrication, reducing wear on those precious engine internals.
  • Better performance: Your Healey will run smoother, with proper oil pressure and less risk of overheating or low pressure at idle.
  • Preventative protection: Removing old oil and moisture prevents corrosion inside the engine. (Think of it as keeping the engine’s insides as gleaming as its bonnet!).

Summary:

Swap out old, moisture-laden oil and filters for fresh replacements to maintain smooth running and protect the engine internals.

3. Inspect and Top Up the Cooling System (Coolant, Hoses & Belts)

Next up is your cooling system – absolutely vital for a healthy Austin Healey, especially as spring temperatures climb (and even more so if you get stuck in bank holiday traffic!). Check the coolant level in the radiator (when the engine is cold). If the level is low, top it up with the proper water-antifreeze mix. If the coolant is more than a couple of years old, consider draining and refilling it with fresh antifreeze mixture for optimal corrosion protection and cooling efficiency.


Now, take a good look at all rubber hoses in the engine bay: radiator top and bottom hoses, heater hoses, and any small bypass hoses. Cold weather can cause older rubber to crack or perish. Squeeze the hoses — they should feel firm yet pliable, not rock-hard and not too squishy. If you see any cracks, splits, or bulges, replace the hose before it fails on the road.


High-quality replacement hoses such as Kevlar-reinforced radiator hoses are available to improve reliability. For instance, a Kevlar top radiator hose has a longer life and better heat resistance than old-style rubber, meaning fewer headaches down the line. Don’t forget to tighten the hose clamps if any coolant seepage is visible at joints.

While under the bonnet, check the fan belt (drive belt) that runs the water pump (and generator/alternator). Press the belt midway between pulleys – it should deflect about 1/2 inch (12 mm) under firm finger pressure. If it’s very loose, you’ll need to adjust the tension (typically by moving the generator/alternator on its bracket slightly). Also inspect the belt for fraying or cracks on the inner side. A worn or cracked fan belt is a classic “perishable” part to fail after storage. If in doubt, fit a new one (Austin Healey fan belts are inexpensive – part of that “cheap insurance” to keep your engine cool). A new belt will ensure your water pump and charging system run smoothly.

Benefits

  • Prevent Overheating: Fresh coolant and good hoses keep temperature under control.
  • Reduced Leak Risks: Replacing old hoses lowers the chance of bursts on the road.
  • Consistent Performance: A tight, healthy fan belt ensures reliable water pump operation.

Summary

Ensure the coolant system is topped up, hoses and fan belt are robust, and everything is leak-free for consistent engine cooling.

4. Check and Test the Brakes (Fluid, Pads & Lines)

Brakes are arguably the most important safety feature – your classic might go fast, but it absolutely must stop well. During storage, brake fluid can absorb moisture (it’s hygroscopic), which can lead to corrosion in brake components and a spongy pedal feel.


Begin with a visual check: look at the brake fluid reservoir (on most Austin Healeys it’s a metal or plastic reservoir on the master cylinder or a separate bottle on the bulkhead). The fluid should be near the “Max” mark and a clear amber colour. If it’s low or looks dark and murky, top it up with the correct type (usually DOT4 brake fluid – we offer Castrol DOT 4 Brake Fluid for premium and long lasting performance). In case the fluid is very old, it’s wise to have it changed.


Proper brake function is critical for safe driving, and bleeding your brakes is essential. While the Gunson Eezibleed kit can assist with this task, we strongly recommend having an experienced mechanic perform the procedure to ensure it's done correctly.

 
 

Now, test the brake pedal gently. Before driving off, pump the pedal a few times; it should feel firm, not spongy, and certainly not sink to the floor. If it feels soft or the travel is excessive, there may be air in the lines or other issues – don’t drive the car until that’s resolved.

Take a peek at your brake pads or shoes: if you have wire wheels or alloys with gaps, you might see the disc brake pads – ensure there’s plenty of material left (at least a few millimetres). If your Healey has drum brakes, it’s harder to inspect without removing the drums, but as long as the pedal is solid and the car brakes straight, they are likely fine for now. Also crawl under and glance at the brake hoses (flexible rubber hoses at each wheel). Feel them for cracks or dryness. These hoses can degrade and are classic “perishable” items – if in doubt, replace them with new ones (standard replacement front brake hoses for your model, or even upgraded braided stainless hoses, are available).

Lastly, on your first drive, do a slow speed brake test in a quiet area to be sure everything is working properly. It’s not a bad idea to disengage and re-engage the handbrake a few times too, just to ensure it hasn’t seized over winter.

Benefits

  • Safe stopping power: Proper brake function keeps you and your beautifully restored Healey safe on the road, avoiding close calls and accidents.
  • Reduced repair costs: Catching low fluid or leaking hoses early prevents more expensive damage to brake calipers, cylinders, or boosters due to corrosion or running dry.
  • Driver confidence: There’s nothing like the confidence of a firm brake pedal when you’re motoring along country lanes – it lets you enjoy the drive knowing you can stop on a sixpence (or at least a shilling!).

Summary

Get your brake fluid levels right, ensure lines and pads are in good shape, and confirm a firm pedal so your Healey can stop on a sixpence.

5. Check Tyre Pressure and Condition (Wheels & Tyres)

Your Austin Healey’s tyres might have lost some air during its winter slumber, and they deserve attention before that first outing. Check all tyre pressures using a reliable tyre gauge. Refer to your owner’s manual or a trustworthy source for the correct pressures (many Austin Healeys run around 28-30 PSI in the tyres, but check for your specific model). Inflate the tyres to the recommended PSI. Driving on underinflated tyres can cause poor handling and even damage the tyre sidewalls, so don’t skip this simple step.

While you’re at it, inspect the tyre condition all around. Look for any flat spots – sometimes when a car sits in one position for months, the tyres develop a slight flat area. Minor flat spots usually disappear after a few miles of driving as the tyres warm up. However, if the car wasn’t stored properly, severe flat-spotting can occur. If you feel a consistent thumping or vibration on your first drive that doesn’t ease up, you might need to have the tyres checked or replaced. Also examine the sidewalls for cracks (often called dry-rot or perishing). Any deep cracks or obvious age-related degradation mean the tyre should be replaced, no matter the tread depth. Remember, old tyres can be dangerous even if they have plenty of tread, because the rubber hardens and grip is greatly reduced. If you need new tyres, be sure to get the correct size and speed rating for your Healey’s wheels.

Don’t forget the spare tyre! Ensure it’s inflated and in good shape, in case you need it. Check that your hammer and spanner for the wire wheel knock-offs (or your wheel brace for bolt-on wheels) are in the boot along with a jack – being prepared is part of classic car ownership swagger.

Benefits

  • Better handling and safety: Properly inflated, pliable tyres ensure your Healey grips the road in corners and brakes effectively, especially important on wet British tarmac.
  • Longer tyre life: Maintaining correct pressure and replacing aged tyres prevents blowouts and extends the lifespan of your set – saving you money in the long run.
  • Improved fuel economy and ride comfort: Correct tyre pressure reduces rolling resistance (helping fuel economy a tad) and gives a smoother ride, so you can enjoy those weekend jaunts even more.

Summary

Properly inflated, healthy tyres are crucial for grip, handling, and overall safety—don’t let flat spots or ageing rubber ruin your spring drives.

Bonus Tip: Fuel Up with Fresh Petrol and Gentle Start-Up

Before you turn that key and dash off, consider your fuel. If you added a fuel stabiliser before storage and the tank was full, your petrol should be in decent shape. If not, petrol can become stale over several months. It’s a good idea to top up with fresh fuel – dilution will help if any is stale, and a full tank also reduces condensation inside the tank (less rust risk). Take a quick sniff in the filler – stale petrol has a sour, varnish-like smell. If it’s very bad, you might even consider draining and refilling, but usually simply adding fresh petrol will do. Check under the car for any fuel leaks (damp patches or fuel odour) especially around fuel hoses and the fuel pump – rubber fuel lines can also age and crack. Replacing any dodgy fuel hose with new ethanol-resistant hose is cheap insurance against engine bay fires (keep a fire extinguisher in the car, just in case – smart practice for any classic).

 
 

When starting the car for the first time post-storage, do it in a well-ventilated area. Turn the key to let the fuel pump tick away and prime the carburettors (on SU carb models you’ll hear the pump clicking until the float bowls fill). Pull the choke out and turn the engine over. It might take a few turns to get fuel through. Don’t crank continuously for more than 10 seconds at a time – give the starter a rest to avoid overheating it. Once it fires, keep an eye (and nose) out for any leaks – fuel, coolant, or oil. Let the engine warm up a bit and settle to a smooth idle. Listen for any unusual sounds. A little valvetrain ticking might be normal until oil circulates fully, but loud knocks or squeals are not! If something sounds off, shut it down and investigate or seek expert help.


Finally, as the Healey warms, check that the gauges are behaving: oil pressure should rise to a healthy level (50+ psi when revved, perhaps 20-30 psi at warm idle, depending on model), and the temperature gauge should climb steadily and then stabilise (usually 70-90°C range). Once everything looks good, take it for a gentle spin around the block. Test the brakes again on the move, listen for any rattles, and gradually build your confidence (and the car’s).

Congratulations – you’ve successfully woken your sleeping beauty! Now it’s time to enjoy the open roads with the wind in your hair.

Benefits

  • Smooth running engine: Fresh fuel (and clean fuel lines/filters) help the engine run without hiccups, and a proper start-up routine reduces strain on engine and starter.
  • Avoiding engine damage: By gently warming the engine and checking gauges, you ensure oil and coolant are circulating before any spirited driving, preventing undue stress.
  • Early problem detection: This careful approach might catch issues (like leaks or strange noises) in your garage, where they’re easier and safer to address than out on the road.

Summary

Freshen up the fuel, check for leaks, and start your Healey gently, watching for any concerning smells, drips, or gauge anomalies.
