I have replaced all hoses, the radiator, the
water pump, thermostat, and reservoir tank
and it is still loosing coolant. I can't see any
visible leaks anywhere, what could be the
2 things...did you purge the cooling system after refilling it? and do you notice a lot of white, sweet smelling exhaust out the tail pipe?
I did purge it and there's not a lot of sweet smelling exhaust but I did see some white smoke and water come out of the exhaust mid day
But you smell a sweet smell? That would be coolant burning off in the cylinders. Water dripping out the tail pipe is just condensation.
Yes it's kind of a sweet smell
Sounds like a head gasket then.
Ok what's the best way to confirm that so I can solve the situation
Doing a compression test on the engine will show some low cylinders, or have the cooling system pressure tested. Taking it to a shop to have it verified would be the best thing to do.
Ok I appreciate the advice a lot thank you
