Tips to Finding Coolant Leaks in Your Classic Car

Posted on

Engine coolant leaks should be dealt with as soon as possible before excessive over-heating damages engine components, possibly causing engine failure. Your second generation Camaro belts, hoses, and spark-plug wires could prematurely fail as a result of excessive heat build-up in the engine compartment.

Before searching for the source of the leak, it helps to start with a clean engine. Engine cleaner in spray cans can be found at your local auto parts store.

It is easier to trace and locate a coolant leak in your second generation Camaro by looking for water stains an other signs on a clean engine. Anti-freeze leaks may travel along different paths before dripping on the ground. A flashlight and a small pocket mirror can aid if the source of the leak is not apparent.

Some easy places to look at; radiator hose clamps, sides of radiator along the tank seams, heater hose clamps, and the weep hole on the water pump. Check heater hose connections at the firewall. From under the car, inspect the freeze plugs on the engine block and the bottom hose clamps on radiator and water pump. Hose clamps can loosen up overtime with the cycle of heating and cooling of the rubber hoses; these should be checked first.

Check the seams on the radiator where the tanks and core are soldered, coolant stains can found here. If your second generation Camaro is not equipped with air-conditioning, using a flashlight, peek through the grille at the radiator core. If the car does have air-conditioning, the condenser will be mounted to front of radiator. You can check the core by removing the top radiator mount and carefully pushing the fan shroud back. Engine block freeze-plugs can be difficult to change if this is the source. Exhaust manifolds can be an obstruction. If extraction of a freeze-plug is not possible at the moment, and the leak is small, a temporary fix is possible using block-sealer or radiator sealer in a can.
