rusty foam in radiator
« on: May 14, 2014, 08:17:08 pm »
I'm getting a rusty foam in my radiator and was wondering best method of testing. Cylinder leak down,  compression test, cooling system pressure test, or that test kit that you stuck up coolant and test for combustion fumes?  Original compression check had all cylinders between 140-150psi, but that was couple weeks ago. I'll have to buy all other testers so I figured I would find out which method is best.
