'86 Dodge Ram 50 small block swap
Coolant system.
I originally had a remote oil cooler in hopes to assist in over all engine cooling. I did not get the results I was looking for, so I flushed out the cooler and now run engine coolant through it. It tees out from the lower radiator hose to a Bosch water pump, then to a Derale 40 row cooler with a fan mounted under the bed of the truck. It returns to a Y in the return heater hose. I already had a FlowKooler high volume water pump which pulls coolant through the little auxiliary radiator no problem. No need for the pump when the truck is running so I just hooked it up to a timer and it runs for a few minutes after the engine is shut down.
The truck never over heated, but always ran between 190° to 210° no matter the thermostat and ambient temperature. After the install of the cooler it runs 180° most all of the time.
I fit the biggest radiator I could and still be able to use puller fans with a shroud and keep the hood latch.
Griffin radiator 24x15.5x3
I originally had Summit Racing 10" fans and switched to Mishimoto's race line 10" fans. But the Mishimoto's fan wouldn't fit, so now my fans are a concoction of Summit housing with Mishimoto motor and blades. The blades acually extend into the fan shroud. Tight fit but it works very well.
Tee out of the lower radiator hose.
The dual fans are attached to the trans cooler next to that is the Derale cooler now used for coolant. Mounted under the bed of the truck.
Bosch water pump. I believe it is from a BMW.
Y back into heater core return hose.
