wanna try using the blue devil headgasket sealer on a 2003 infiniti g35. my question is. its says remove the thermostst while running the blue devil through. so what do you do with the hose how do you keep it running with no thermostat
You have to take the thermostat out and then out the hose back on so it can build up pressure in the cooling system. Remember your just treating a symptom, not a cure. Good Luck
