Fan Clutch?

[Denisefwd93]

This is a pretty good video it's long and kind of boring but he covers when the fan clutch is bad in the good way too much cooling and making noise at all speeds which is going on with the one in my truck.

Turns out my next door neighbor has clutch wrench tools and a good 36mm open-end wrench but it's not budging!
Hopefully the shop I'm taking it to tomorrow or Wednesday has the air tools

We didn't even try the reverse Direction because everything instructional says it loosens in the same direction as the fan turns which makes sense and more than one video shows it that way

Pry worried over nothing....heres where it sat and never moved...higher then id like but whats yalls opinion?

Only time i got it to creep upwards was when i got home and turned the blower on...i think i need to diagnose electric not cooling, the heater hoses wernt even hot enough for me to pull my hand away. T stat hasnt locked in failsafe, still hits temp in 3 or 4 miles@ 55* or so.

That temp seems kind of high to me, on my 84 Ranger it used to sit closer to the bottom to the middle of the R normally. It would rise up like in your picture sitting in traffic for a short time with the AC on but would cool right back down if the AC was shut off, or tranny put in neutral and engine revved up a bit, or I started moving.

If your fan is working properly it should be keeping things cooler than that unless you have a 200 degree or higher thermostat...possibly air in the cooling system, I know in my 84 Ranger and 84 Bronco 2 the damn thing was a pain in the ass to get the air out of the cooling system after replacing a hose.

My 88 Bronco 2 I installed a 180 degree thermostat and the temp runs right at the bottom of the R all the time. I have to be stopped with the AC on for quite a while before the temp climbs to anywhere near a worrying level. I replaced the fan clutch in mine last year, pain in the ass to get the dang thing lose, finally got it though, but you gotta have some slim wrenches to get in there. The fan clutch I got was a heavier duty one so it is engaged for a while first thing in the mornings, and I find it engages pretty early on which is good it keeps things cool in the summer heat.

I do have a 180* tstat.

The issues seems to have resolved itself, now it hangs around the R. Unless its a hot reatart youll get an O untill you move a bit.

Should run just below 1/2 after full warm up.

But thats with 190-195degF t-stat

Should be slightly lower with 180degF installed

T-stats start to open at +/-3deg of rated temp, but are not fully open until 10-15deg above rated temp

I'd not put a whole lot of faith in the dashboard temperature gauge. I love my handheld infrared thermometer.

just a report back. The shop changed out the fan clutch with an air chisel on the big nut, it took about 10 minutes! Friends and me have been dealing with this going on two weeks lol.

This thing isnt overheating, although the gauges are still wacky. I can watch the fuel and temp both max out at the same time.

I gotta change universals this week on it, im gonna change that groundstrap to.

I'm beginning to suspect the coolant temperature sensor on mine, because it's not warming up by the gauge and throwing a 172 code, but my infrared thermometer tells me it's right up there where it should be.
