My radiator is full to the brim but the tank is always low for the most part. It's a class 2 leak of coolant
My car has an automatic transmission.
Hello. If the engine is leaking coolant then the reservoir is always the first part to read low. I usually start by checking for any visual leaks on the ground or on the engine. The most common cause of a coolant leak on this engine is the intake manifold gasket, the radiator, or the water pump. If no visual leaks can be found then I would do a pressure test of the engine as the pressure would help to produce the leak. If nothing is found at that time, then a dye test could be done to find the leak. If you want to have this looked at, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose the leak and move forward with the proper repairs.
