Re: Radiator flush fluids

Does your car overheat due to a clogged radiator? If not, I would not use any flushing compound due to the possibility of causing leaks. If you have an overheating problem, I would try flushing the radiator and block with plain water first, and make sure your water pump is not leaking at the seal. Water pumps can leak air IN when the engine is running, and mimic overheating and boiling due to aerating the coolant.
