A cheap trick ……..or secret….is Ford’s Factory Oil Coolers that they put on all 2.3 Turbo motors. They were also found on the SSP Police Mustang 5.0’s. If you go to a junkyard and find a Turbo Coupe T-bird or Merkur XR4ti it will have a cooler on them.
Look at the oil filter. Remove it.
- There is a 90-degree elbow there. It takes a 3/4 socket to remove it.
- Then you will see a round coupler with two heater hose’s going into it. This is the cooler.
- Cut the two hoses.
- There is a larger bolt holding it to the block. You will need a 1-1/16 socket to remove this.
You now have an oil cooler.
Now all you do is ……
- Clean it up
- Put on ANY Ford motor that takes the Fram F8A (Inside Thread Diameter 3/4″-16) or equal
- Route your heater hoses into this unit making a loop so that the coolant is running through the cooler and back to the water pump.
I buy these from the Junk yard and then go buy 10-feet of heater hose and hose clamps. Your engines coolant does ALL the work. It will cool your oil by 30 degrees and raise your coolant temp by 2-degrees. Racer Walsh sells them for around $180.
Every Ford I own gets an oil cooler installed the week I buy it. I really believe it is a must for a 2.8 V6
