Burning? Getting into combustion chamber through blown head gasket? Do you have any white smoke?

No smoke and runs about 195 to 200 degrees

The plastic topped radiators are well known for leaking. Check inside the shroud and see if it is running down the passenger side of radiator, how does the underside of the water pump look? Check for whitish streaks there and on thermostat housing, most coolant leaks leave a snail trail of white streaks if they are temperamental leaks. If all is good there pop the oil cap and check for signs of water/oil mix.

Mine did exactly that. The plastic crimped seal on top was slowly leaking and dripping down slowly enough not to leak on the ground. I can smell the coolant while driving and while in the garage. The pic below shows the left side leaking.

Thanks for the picture beast! I am trying to help a friend fix her Jeep right now. I think she may be having the same issue.

A worn-out radiator cap can 'invisibly' lose coolant as well. The spring gets weak, allowing steam to escape to the overflow, where most of it evaporates before it can condense.

I have already replaced the radiator and water pump. I put die in the radiator but have not seen it anywhere. I will try a new cap. Thanks for the help
