Coolant wasn't going to recovery bottle. Replaced the radiator cap. I know there are two brands of possible radiators but I don't know how to tell the difference. The car was purchased used so I matched the cap that was on it. Ran the car until the upper hose was swollen and hard. Still no activity at the recovery bottle. Found a clog at the plastic joint going into the recovery bottle. Cleared the clog that looked like clay. Still nothing at the bottle with the engine hot. Both radiator hoses are hot to the touch. The temp gauge doesn't work and the heater core may have a partial clog. When the car was turned off, I could hear a slight low volume high pitched squeal like air escaping. I found that if I slightly rocked the cap, the squeal changed in pitch. The only recovery bottle activity was when I moved the cap slightly to the open direction. The pressure then moved quickly into the bottle.
We drove the car with an Actron elite scanner connected and found that the temperature would climb to about 235 degrees while sitting still and drop dramatically when the car began to move again. The outside temperature at the time was 30 degrees.
I know I need to flush the system but is there a problem with the new cap? Does anyone know how to tell which radiator I have? I have heard that a Denso has a 4 blade fan and the other one has a 5 blade fan. This car has two fans, one 4 blade and one 5 blade. Is 235 degrees too high? I'm really at a loss!
have the same problem?
