Overheating when going uphill - "SOLVED!"
My '96 Taco overheats when I go uphill or make her work a little in snow and such. I thought it was the viscous fluid coupling (Fan clutch), ordered a new one, but it made no difference. The rad is not plugged with mud/ snow, etc. Both rad hoses warm up. I changed the antifreeze. She is fine when idling or driving in town or on the highway. This only happens when she has to work a bit.
According to my FSM, the thermostat has 2 phases, and I am beginning to think the second phase, i.e. full-throttle opening, doesn't happen. I suppose this would be the next thing to check (on the stove), unless anyone has a better suggestion. Any ideas? Thanks?
