Engine Cooling problem
1996 Geo Tracker 4 cyl Four Wheel Drive Automatic 160000 miles
My 1996 Tracker overheated resulting in having to have a head gasket, bearings replacement. The mechanic also replaced all belts, water pump, and thermostat(2 times). He also did a compression test on engine and radiator before and after the head gasket repair and had the radiator serviced to ensure no leaks. I drove it approximately 500 miles and noticed the heat guage edging toward HOT. The mechanic adjusted the lifters, oil change, replaced the thermostat for the third time and replaced the fan clutch. He test drove it on highway and mountain roads and the heat guage stayed in the middle. I drove approximatly 75 miles and the heat guage started fluctuating between middle and 3/4. I had to replace about 16-24 ounces of coolant and the reserve was dry. There is no evidence on hoses, beneath the car or anywhere visual of coolant leaking.
Any ideas what else it could be or what my mechanic could troubleshoot?
