How To Stop Your Classic Car From Overheating This Summer

Summer’s almost here, and, one of the biggest headaches on hot days in June, July and August is how to prevent overheating under the bonnet (and behind the wheel).

Your classic car was probably built before electric fans, extreme weather testing and maybe even traffic jams. So how can you and your car keep their cool?

Regular checks
Regular checks of belts, hoses, radiators and fans could save you hundreds of pounds before the summer even starts. Remember, your vehicle’s temperature gauge is your best early-warning system.

Don’t ignore the tell-tale clues. Engines are built to operate hot for best efficiency. But not so much that they become overheated and damage themselves due to overpressure or coolant loss.

Get in the habit of proactive maintenance and checks. It takes far less time to do this that the time you may spend waiting for a tow to the garage or the breakdown repair van to arrive.

Radiator caps
A change of radiator cap could make all the difference. You can buy caps four times as heavy and resilient as the standard 4lb one.

Radiator fans
Get this changed and you could treat your radiator to more airflow. Therefore, reducing the likelihood of overheating.

Hoses and belts
These should be replaced every five years, no matter how often you may drive. Cracked and frayed belts and hoses should be replaced and disposed of at once.

Exhaust wrap
One useful trick of the trade is to put exhaust wrap on all exhaust components and headers (except mufflers and catalytic converters). It means that less exhaust component-generated heat goes beneath your bonnet.

Exhaust wrap also reduces the density of exhaust gasses, meaning they can escape more quickly.
