New engine, less than 50 miles, over heats, fan fuse blew, dealer can't find problem
First and foremost, thank you in advance for the help!
I had my engine replaced by a dealership 250+ miles away because the engine went while away from home. I Trailer Queened the car home after the repairs because I did not want to break the engine in on the interstate at constant speeds. The engine has less than 50 miles since replacement and the 40 amp fan fuse popped. Below is a recount of the over heating experience.
When the engine was replaced the coolant hose to the throttle body was left undone and gushed coolant all over the engine when they pressure tested the system before starting it. The dealership then washed the engine down afterwards before I took delivery of the car.
While driving I noticed that the AC compressor would not stay on while idling in traffic and of course the AC was blowing warm air at idle. Once I began moving the AC began cooling again. Driving along in city traffic with the AC on, the engine died under way and then fired back up within 1 second while driving. I made it 100 feet further and the temp gage began to rise to the half way mark. I rolled into a parking lot and shut it down. I watched the temp gage rise to between the half way point and the H with the engine off. Once the engine temp cooled I started it and drove it the 1 mile to my house and it did not exceed beyond normal operating temp (left of center).
I did some research and I checked the 40 amp fan motor fuse, it was popped. I replaced it and had Mazda roadside tow the car to the closest dealership (not the dealership that replaced the engine unfortunately) to figure out the problem. Not my choice, but the dealership that replaced the engine is 250 + miles away and Mazda roadside would not take it that far.
The dealership has had the car for 3 days and cannot duplicate the problem. They have tested the fan motors, checked for the rubber grommet in the shroud (all correctly located in the air box) and road tested the car with the AC on with no failures. They claim that the fans are running at the correct speed and load.
The car has 84K on it and is a 2005. Are my fan motors the problem? At this point, I don't trust that there is no problem.
