Home/Cooling

Cooling

This department covers the parts that carry heat away from an engine, a transmission or a turbo system: remote oil and transmission coolers, radiators, water pumps, intercoolers, thermostats, and fans and shrouds, along with the caps, gaskets and brackets that go with them.

Oil and transmission coolers are the largest group, most of them from Derale. Remote coolers are listed by the number of passes and the core length, such as a 6-pass or 8-pass core at 14 inches or 18 inches, with -6AN ports. More passes and a longer core give more cooling area; the practical limit is usually the space in front of the radiator and the hose routing to reach it.

Radiators come in two kinds. Direct replacements from Crown Automotive match the factory part, many of them for Jeep models. Universal and race radiators from Proform and PRW are sold by core size, by Ford or GM pattern and by transmission type, and some come as a system with shroud and fan, which saves matching those parts yourself. Check whether a universal radiator is specified for a manual or an automatic transmission before ordering.

Water pumps and thermostats are listed by engine; Edelbrock water pumps, for example, name the engine they fit. For turbocharged engines, the intercooler section holds cores, brackets and boost tube kits.

Vehicle-specific parts are strongest for the Chevrolet Corvette and Camaro, Jeep Grand Cherokee and Jeep Cherokee, Chevrolet Blazer, Chevrolet C10 and Ford Mustang. Each product page lists the years, makes and models it fits, and the vehicle selector filters this page to your vehicle. Related pages: thermostats and hose and fittings. Prices are in Canadian dollars.

Radiators, fans and shrouds, transmission and engine oil coolers, thermostats, hoses and coolant — Derale, Crown Automotive, Edelbrock and more.

Heat is a towing and a modification problem before it is a summer problem. A transmission cooler is the single highest-value addition to a truck that pulls a trailer, because automatic transmission fluid degrades sharply above roughly 220°F and the damage is cumulative rather than sudden. Engine oil coolers do the equivalent job for a hard-worked engine.

An electric fan conversion frees the parasitic drag of a belt-driven clutch fan and gives you control over when the fan runs, but it is only as good as its shroud — a fan without one pulls air through the easiest path rather than through the core.

Most listings here carry verified vehicle fitment, so you can filter to your own year, make and model rather than guessing from a part number.

Cooling failures are usually a system, not a part. Coolant side: radiators, water pumps, thermostats and housings and fans and shrouds — a fan without the right shroud moves far less air than its rating suggests. Charge and oil side: intercoolers and charge air for a boosted engine, oil and transmission coolers for towing heat that the radiator never sees.

Fitting a particular vehicle? We list what we carry for Chevrolet Corvette, Chevrolet Camaro, Jeep Grand Cherokee and Chevrolet Caprice on their own pages, each filtered by manufacturer fitment data.
