I have been unable to determine the root cause of my 2000 Trooper (96K miles) leaking anti-freeze; about 1 gal per 5K miles. The dealership has done the pressure tests and check of the heater core. There are no deposits on my garage floor. When I suggested the loss could be absorbed in the engine, the dealership advised me to look at the exhaust, would be whiter than normal.
Does anyone have any advise on where to go from here? Although I have 24K miles left on the power train warantee, the dealership is not going remove the head without probable cause.
One last question - should I consider adding one of the stop leak products to the radiator? Naturally the dealership does not advise doing this.
