I have a 90 240 and a 93 240. Both are auto and base model, not DL or anything else. In trying to solve my temperature gauge probelm, can I switch parts between the two? I was thinking to switch the fan clutch from my 93 to th 90 to see if it solves the problem. I was also thinking to swtch the coolant temp sensor. Any advice welcome. P.S. I cleaned the radiator and AC grill in front and it didn't make any difference. I use a VERY, VERY low pressure washer (~400-500 psi). Did a good job as long as you stay about 12"-18 " from fins.
