Radiator leak

have this checked for a head gasket failure have it pressure checked first. Then there is a chemical they can add to check further.

pressure check has been done.

when it is hot check radiator for cold spots if it has those as well as loose/green colored fins on edges and bottom or just cold spots then the rad is bad. I am assuming the thermostat is in good condition and not stuck and no leakage anywhere on engine like hoses or freeze plugs.

I have replaced the water pump, heater hose connector ,coolant sensor, thermostat and the water pump adapter housing. I will check for cold spots next.

Hey John,

Have you checked the passengers side floor for coolant, sometimes when the heater core let's go it can leak there. Also can you do a chemical check for a blown head gasket?
