Thermal fan issues
So l have 99 1500 2wd with the 5.9 gasser .
The problem I've had the last few weeks is the thermal clutch fan wont release and " freewheel" it wants to stay constantly fully engaged even at 4k .. I've went from about 300 miles to a tank down to 190 ish .....
grant it I know the trans is acting up and wont downshift properly and upshifts early since the bands got adjusted ..
I've tried replacing the clutch fan twice and the thermostat and it has a 195 in it and still no difference ... Its never gone over 200 since I've owned it.. the upper radiator hose is HOT like it should be and the lower is warm. And both have good pressure in them ..
I've got a temp sensor in the trans pan and it only gets about 120 so its not like that's too hot causing the fan too be constantly engaged
Could the radiator be partially clogged but not enough to cause it to over heat.. I've got a temp probe by the top radiator hose and the hottest that's read that I've noticed is 160ish
Any input would be helpful.. im about to just goto dual efans from the dyi links as im stumped now
