Got the ranger back together, the good: no leaks, went together quickly . but…, the bad: still not getting warm enough, I think the issue is the thermostat doesnt fit like it should in the housing . After a 8-mile run my laser temp checker said it was only at 170. And quickly started dropping off as its idling. Just about have to pull the fan (again) to be able to work on it. When I first got the truck there was a pinhole in the neck right below the radiator hose connection . I clamped a peice of rubber there for awhile then eventually replaced the whole thing (napa part) Hopefully I can find the original & see if a thermostat fits better. I remember my ‘88 always had a bad airlocking issue when the cooling system was refilled and Ive never had that issue with this 2.3 I also could get a thermostat that fits inside the hose (ford N series tractor) I might try that first, assuming the tractor thermostat isnt a fortune. Spent rest of the day finishing a ventless propane heater project I started before thanksgiving. That stainless gas line is awesome, drilling through block isnt. My cordless harbour freight drill worked good, maybe too good. couple times it caught & spun the drill around , twisted my wrist & once it got me in the nose.
Edit: scratch that N-series tractor thermostat, they are $25, only available in 160 degree, and im not even sure the size (diameter of thermostat to fit snugly in hose) is correct. Time to explore other options, maybe another year of the lima has a better design to keep the thermostat in place. I’ll see if I can find the original housing first, I tend to hang on to stuff I should throw away- I still have a 3.0 V6 radiator from a engine I gave away almost 2 years ago.
