The cooling system is designed to remove heat generated by the engine.
Most muscle cars had adequate cooling systems. If it didn’t overheat before, but now it does – you need to identify and repair the problem – not reengineer the cooling system. However, heat is power. If you alter your engine to make more power – you may need to upgrade the cooling system to handle the additional power demands.
Our radiators – are original looking replacements, not generic service replacement units.
Mopar radiators aren’t straight forward. They primarily used 2 different sized radiators – 22″ and 26″ wide. Cars with Air conditioning or “max cooling” would get a 26″ radiator. Cars without A/C generally got a 22″ wide radiator – this includes big block engines. In otherwords, not all 383 HP engines had max cooling (and therefore didn’t get a 26″ radiator).The other issue is the hose locations which differ between years and radiator size.
Mopar radiators can be identified by a mopar part # on the top of the tank. This is useful in figuring out why shrouds or hoses aren’t connecting to a radiator “when they should”. If you have a 1968 C-Body radiator in a 1970 B-body – the B-body shroud usually won’t fit correctly.
You can’t directly install a 26″ radiator in place of a 22″ inch radiator as the core support is designed to accomodate a specific style.
Shrouds – generally during this era, shrouds were safety items intended to keep your fingers and arms out of the spinning fan. Lack of a shroud doesn’t automatically mean you’ll have cooling issues.
