Coolant over pressure

Postby Mick83 » Wed Jul 15, 2015 12:57 am



I'm really at my wits end on this, I have a 83 Aspencade I rebuilt the front area including new water pump, gaskets, o rings, Etc. Etc. got everything together and coolant was spewing out of the cap. So I went to my local auto parts and came up with a new one. was fine on a 40min ride to a show then home. a week later I rode it and it started leaking again and now it just keeps getting worse every time I ride. Has this happened to anyone else :oops: :shock:

sounds like it's the wrong cap or the lip of the tube is damaged. Caps have different pressure ratings/spring tension.

That's, a good place to start. I have some numbers for replacements I remember the guy at the counter comparing to the old one and the pressure rating on the original was I think 9lbs and the new one was 6lbs it worked for awhile. I didn't think of the tank collar, I did have it out laying around the garage. Thanks, :)

Also check the outlet leading to the coolant reservoir. If it is blocked, when the coolant heats up and expands, the only place it has to go is spurting out from around the cap.

9lbs sounds a little low on the cap. try a 13lb cap relief pressure is 10.7-14.9 as per the service manual.

Thanks, I did that and it's good unless it's bending when I set the tank back in. I'm going to stop and buy a Thermastate on the way home.

Going from a 9lb cap to a 6lb will mean the car "pops" earlier (at a lower temperature). I agree with redbug - go for a 13lbs cap.
