This is kind of long. Two weeks ago, I changed out a faulty water pump that I bought and changed last summer. As I was pulling the water pump out, I bent the PCM connection to the Opti and didn't realize it. After I got everything put back together, the car was in a no fire condition. So, after seeing no spark from the coil, I realized that it was a PCM connection, and thats when I saw the opti PCM connection was broke, so I bought a new Opti and put everything back togehter and the car ran great for a week. Until, this last Friday, the car was setting in the driveway at operating temp, and all of a sudden the hose came undone that connects to the bottom of the radiator. I clamped it down really tight filled it with coolant again, and bled the lines. Then, yesterday, the car did the same thing again as I was leaving my apartment. So my friend and I this morning put two clamps on the hose, and filled it with coolant and bled the lines. Car was running great for about two hours, then same thing sitting in the drive way at idle, and the hose blew off again. So I went and bought a new hose, and radiator cap. Replaced hose, filled car with coolant, and as I was bleeding the line while the car was running and all of a sudden it died. Now, the car again is in a no fire conditon. So, I pretty sure my Opti got runied due to all the coolant, but some please give me some ideas on why that hose keeps blowing off. I reallly need the help, I'm getting pretty fresterated. Thanks guys.

 

Could a bad radiator cap be causing this to happen, building pressure and then blowing off the hose?

 

what type of clamp?

are you using a new clamp or reusing an old one?


a bad cap MIGHT cause it, but caps usually fail by opening too soon

 

I'm using two new screw down clamps. I can't pull the hose off at all, but it keeps coming off.
