Hey guys,
i thought i’d run my problem pass you. Hopefully someone has experienced the same issue and can point me in the right direction.
Heres the deal:
1999 Ranger XLT 4x4 3.0L auto transmission.
When I start the truck, I let it warm up to normal temp and then drive. It does good for about 2 miles then the temp gauge starts climbing. It will continue to rise unless to turn my heater on. At that point, the temp will begin to fall and goes back to the normal position (slightly below 1/2 way on the gauge).
I can drive to truck all day with the heat on, which sucks on a 90 degree day.
But if I turn the heater off, the temp will start climbing again.
Any ideas what’s going on?
i don’t think it’s a head gasket because the oil not milky, there are no bubbles in the coolant with the cap off and idling, and no coolant/white smoke out the tailpipe. ????!
possibke heater bypass is clogged up and only letting coolant circulate through the heater core???
🤔🤷🏻-♂️
