Step 1
Update the radiator system in your classic car by replacing hoses, belts, water pump and other cooling components.
-
Step 2
Install a new thermostat that only allows the car to run at an optimum temperature without overheating. Classic cars use outdated thermostats, so this is the best way to keep you engine cool.
-
Step 3
Make sure all the filters are clean. Dirty air and oil filters can interfere with proper air flow and lubrication.
-
Step 4
Keep coolant levels at appropriate levels for your engine. Do research on your particular type of classic car engine so you're up to speed on all its particular needs.
-
Step 5
Check all fluid levels before taking your classic car out for a drive.
-
Step 6
Run your classic car for short amounts of time especially in warmer weather. Sitting around in traffic can cause cars meant for cruising to overheat more easily.
-
Step 7
Get your coolant system completely flushed and cleaned once per year. Flushing and cleaning removes all unwanted debris and worn out coolant. The radiator system is then filled with fresh, clean fluid which is more efficient at cooling the engine.
