Need coolant diagram! PLEASE HELP!

[elementalwindx]

I have had a bi*** problem with this stupid coolant system on my 95 gst. I keep getting small bubbles coming from my radiator cap, and I have resurfaced, cleaned, pressure tested my head, put a new hg on and everything, and replaecd the thermostat, rad cap, and turbo return hose, top rad hose, and a few other small hoses, even the water pump is brand new. I NEED a diagram to see where ALL the places that coolant goes, so I can narrow down all the little pinholes that it might be coming from (IE: rubber hoses I dont know about)


Thanks guys! and YES i have been searching for a while now without any luck!

Change your radiator cap. Also, have you checked your heater hoses,

You won't be taking in any air from pinholes, you'd be losing coolant out them. All you might be getting bubbles from is a head gasket leak. Test the coolant for hydrocarbons to confirm.

Do you mean a block tester? Injects some blue liquid into the coolant and you squeeze it and as it comes up, if it turns green, it means you have exhaust getting into the system?

We did that 3 times and it turned up just fine.

That's the stuff. Or, a smog sniffer at the top of the coolant with the radiator cap off. And I think they're making test strips for it these days, too.
