When fluid temperatures exceed 180 degrees, the thermostat's interior valve closes so that 95 percent of the oil will be directed to the cooler. When the temperature falls below 180 degrees, however, the valve opens, allowing 90 percent of the oil to bypass the cooler and head back into either your engine or transmission. Preventing that fluid from entering the cooler will help to raise its temperature faster so your vehicle will be ready to go sooner - no more long waits, no more cold-oil shock. When valve is in bypass mode, 10 percent of the oil is still allowed through to the cooler to maintain constant system pressure.

Mount with Mounting Bracket Kit for Derale Fluid Control Thermostats (D25793).

  • Adding an Engine Oil Cooler and a Power Steering Cooler to a 2007 Toyota 4Runner SR5 4.0L V6
  • Thanks for asking about a Power Steering Cooler and Engine Oil cooler for your 2007 Toyota 4Runner SR5 V6. Adding two more coolers is not going to present a cooling issue for your engine/radiator. The coolers allow air to flow through them and will not transfer enough heat to the air going through them to effect the cooling performance of the vehicle's radiator. Your engine oil filter has 3/4-16 threads. So you can determine the correct threads to use from the recommended kits below,...
