The thermostat is like $7, so that's a cheap fix. DId you say the fans were not coming on? I just need to know so I can send the both if needed. The fan switch is the one on the thermostat housing, and the temp sensor is on side of the head.it's dirty and broke. i got the spark plug out. just need to get the coolant temp sensor and a thermostat and i'll put all of that back together, including the distributor
