The usual things done before storing an car are:
- Coolant system flush and fluid change.
- Engine Flush and oil change.
- Brake system flush and fluid change. (could be skipped)
- Clutch system flush and fluid change. (could be skipped)
- A damned good clean.
This is to make sure no significant amount of corrissives in the coolant and oil are present, and there is a minimum amount of water in the brake fluid in the Brake and clutch hydrolics (non-silicon based brake fluid is hydroscopic - it quite happily absorbs water - which eventually leads to steel brake lines rusting from the inside out...)
Once you've parked your car up:
- Jack it up and put it on blocks. This prevents flat spots on the tyres.
- Disconnect the battery and remove from the car.
- Make sure the handbrake is not applied.
- Drain the fuel tank.
When you come to take the car out of the garage:
- Charge up the battery (you probably should do this once every few months), and but back in the car.
- Check the tyre pressures. If any tyres are grossly under inflated (less that say 20psi), pump up the tyre.
- Check that the brakes and clutch work, and that the wheels turn freely out of gear with he brakes off.
- Put the Handbrake on and take the car off the blocks.
- Pump up the tyres.
- Roll out of storage
- Check all fluids - coolant level, engine oil, brake and clutch.
- Take out the spark plugs and squirt a few cc's of light oil in each cylinder around the cylinder walls, wait a few minutes, then turn over the engine by hand. This is to make sure there's some upper cylinder lubrication - any oil that was there will have drained away!
- Crank the car for about 15 seconds. This is to prime the oil pump.
- Put the spark plugs back in.
- Fuel the car up.
- Start the engine. Watch out for smoke from the oil you've just put into the cylinders!
- Check that the oil pressure light goes out/oil pressure reads OK.
- Go for a short drive to make sure things seem right.
