cooling system pressure?? too much??
I have a 89 t2 and I replaced thermostat, got a koyo radiator,aftermarket radiator hoses. I burped the system for a LONG time and got all the air out even revd the car and squeezed the hose. Now when I went home from work I checked the hose and it was pretty freaking tight. Now I know the koyo is supposed to have higher pressure but this high did I not get out the air? Or is there something else thats wrong? And I tried the champagne test and no coolant gushing so I'm bout to be stumped..

I just felt the house being super tight..and the cap I got was off my old radiator that I got from mazdatrix reading 0.9.. car has been doing this for a while even without the koyo and hoses. But I remember a hose on the firewall I had to cut shorter cause it was to right and had coolant coming out so maybe that's drawing air?

^This. Don't listen to whatdidusay, not that he has any good suggestions anyway. Check that your coolant overflow line isn't clogged. Go buy a new cap, they're what $5? You don't need a high performance (or high pressure) radiator cap.

I'm here to do what I can to help and to learn , respect that or don't even talk to me , or mention my name.

I haven't tried the other cap yet so I decided with why not and I have switched my other overflow hose back on which fits a lot tighter on there so I'll let you guys know tomorrow I really hope this fixes the problem

Have you actually confirmed there is a problem with your coolant system pressure with a gauge? A rad hose pressurized to 13 psi is pretty firm.
The system will only over-pressurize if it can't push coolant to the overflow. As a test, dump the contents of the overflow container and refill it with plain water. After the next drive look and see if any coolant is now mixed into the water.

Its just the radiator hoses that are just over pressurized I noticed all other hoses are fine they have pressure but not to much is it cause of the koyo rad?

Well I know I had to trim the bottom hose but its not restricting..I'm bout to say I'm gonna get every line and part in the cooling system I'm gonna buy new..lol I almost gave up on the car cause it lost power while I was pushing it and it was the intake tube by the cone wasn't tight so that came off but anyways yaa i know it has to be something simple
