I only use Gates now after some cheap ones failed but didn't leak. Gates are very good. I have not had to replace one.

Pros: Gates are very good

Cons: cheap ones failed

Your thermostat is probably stuck open. Replace it with an OEM Motorcraft version, not aftermarket.

Pros: OEM Motorcraft version

Cons: not aftermarket

I used a motorcraft RT-1139 thermostat. Comes with a jiggle valve to help bleed air already installed and cost me 8 bucks. You won’t find any place that says they fit other than some forum posts but they do indeed work, I installed one on my MJ with the only issue being me not refilling the radiator after dumping all the coolant.

Pros: works well, jiggle valve, good value

Vehicle: Jeep

Part number: RT-1139

I always use Premium Thermostats, which are billed to fail open. Gates or Stant are my favorite brands.

Pros: fail open

I replaced the thermostat from a non-OEM to Motorcraft about a month ago, and the only difference has been the speed at which the dial moves from higher temps to its normal positon.

Pros: faster dial movement

Vehicle: Ford Ranger

I installed a Gates one a couple months back and it worked well for a little while; engine got up to operating temp fairly quickly and stayed there, but now it’s running really cold no matter how long or how hard I drive it. Think it’s stuck open.

Pros: quick operating temp

Cons: running cold, stuck open
