Hi all,

I overheated one day, I thought it was the thermostat, I bought a new one, put it in and the car worked fine for a few weeks, I thought my problem was solved.

Then it happened again, so I got another thermostat, but this didn't fix my problem. Looked at the fuses and realized that I had blown my #5 fuse (40A) for the radiator fan.

I replaced the fuse, drove a little (day or so) and it blew again.

I then flushed the coolant, put in a 3rd brand new thermostat and replaced ALL my fuses (I bought a bag of fifty 40A fuses from Amazon because why not).

I'm assuming that I have a short somewhere? Has anyone had this issue? What was the fix? I'm guessing it's not my thermostat at this point, right? I'd outright replace the fan but I'm worried that the actual power line to the fan might have a short in it.

I'm open to all suggestions.

 

you probably have more than one problem;

one being the condenser fan it is probably starting to go, gets hot seize temp. and blows the fuse.

but you should not need the condenser fan if your cooling system is in good shape, it is really only there for driving in traffic; if you have air flow across the radiator it should stay cool without the need of the condenser fan.

By over heat do you mean steam came out or the gauge went into the red?

 

What does 'short' mean to you ?

Spin the fan by hand. If stuck or hard you need a new fan motor. If spins freely, power it directly. If smokes, you need a new fan motor.

 

Check the wires where they come around the passenger's side of the engine down from the alternator area.

These wires need to be routed correctly and are probably chaffing as a previous owner probably did not secure these wires for the last cylinder head repair.

Check the motor.
The blade must not have any side to side movement.
If it does, the bearings in the fan motor are shot and the motor is sticking.
