Hi Scotty,
I have a 2014 Toyota Sienna LE FWD with 85k miles on it. Recently I noticed a coolant leak from the headgasket. I checked the oil dip stick and it seems that the engine oil and coolant are not mixed. I viewed your YouTube channel about the blue magic sealup that you use for coolant leaks. I was wondering how much sealup I should add in the radiator? Also since it's spring time....I can run the car with water in the radiator until Fall? Can I switch back to coolant during winter time? It won't affect the seal? Let me know
I can still drive my Sienna before I fix this coolant leak issue?
Any sealant you use is going to be a temporary fix and eventually, you'll completely blow the head gasket, and possibly damage the engine. The correct fix is to replace the head gasket. It is a very big job.
