On the v6, I believe they're located at the bottom front of the motor.

Here's a link with info: http://www.fordpinto.com/general-pinto-talk/running-warm/msg27994/#msg27994

The thermostat is at the lower radiator hose. The housing is located in front of the water pump. There are three 10mm headed bolts holding it on. They thread into a 90 degree bypass nipple behind the timing cover.You will need a new thermostat, flat rubber gasket, housing gasket, nipple gasket. Its a bit tricky getting it all in place to bolt together.You said its running hot. How hot? I have had mine since new and it most always runs at the high end of normal on the factory gauge.

I don't have a temp gauge so I don't know exactly how hot but the coolant is boiling through the hose at the cap so I also installed a new rad cap.

What is the purpose of the small hose to the T-Stat housing? There is no opening for coolant to flow. Anyone know?

The small hose ,5/8 dia, is the heater hose. dont know what you mean by" no opening for coolant to flow" unless it is corroded shut.

You'll want to clear that hose fitting out. Could be part of your issue. You might want to check all your other connections for clogs, and then run a couple cycles of 'Super Cooling System Flush' through it. Sounds like it may have been neglected by a PO at some point.

Good luck!

I'm pretty sure a head gasket is the problem. Will a 2.8 from a 1984 Ranger swap in place or is there any difference?
