Radiator
Three selections are available for your early C4 model Corvette!
- Single Row
This radiator is built with a single row of 1.5" tubes. This design increases cooling surfaces by 50% over the stock unit and is an excellent choice for the economy minded customer that wants to eliminate failures from plastic end tanks and gasket leaks. This unit uses the same full size aluminum end tanks as our double row version which increases fluid capacity.
- Double Row
Another all-aluminum radiator featuring two rows of 1" tubes and press formed end tanks. This doubles the cooling capacity of the original single row units and eliminates failures due to cracked plastic end tanks and/or gasket leaks. This model is designed for an automatic transmission with an internal cooler built in. To simplify installation, we include the custom mounting cushions. First design AC condensers used on 1984 & early 1985 models will have to be upgraded to allow clearance for the thicker radiator.
- LS Swap
The LS engine upgrade features an all-aluminum construction with the same press formed end tanks for longevity and performance. This radiator is a double pass design putting the inlet and outlet on the same side to simplify engine plumbing. The steam port bung is welded into the upper part of the tank for proper ventilation. A sensor port is also included that can be used for a coolant temp fan switch.
