Overheating will cause air to be drawn into the coolant lines this causes an air bubble to collect at the thermostat. The air bleed screw at the thermostat is there to bleed out the excess air. The wiring jumper (bridge) is a after market modification to by-pass the Fain Fail relay which has a 98% failure rate.

Vannatter <windance@xxxx> dmcnews <dmcnews@xxxxxxxxxxx>; Would appreciate analysis of my recent problem to help me pin point correction:; Problem: Overheating occurred during our last town trip. rattling noise began in the engine, noticed that temp war rising. Stopped to check and found that the fans were not working. far left circuit breaker (#23) I think,in section 3 sub 7 group 4 ) showed to be bridge within itself with 2- 20 amp fuses. one of which was melted. Replaced the burnt fuse and had fans but still no cooling. Suspect the problem of a stuck thermostat? Am I on the right track? If so why would the fuse be bridged as it is. Fans do work now. ------------------------------------------------------------------------ To address comments privately to the moderating team, please address moderator@xxxx
