Well, I was coming back to work today from a weekend of camping and volunteer work. I noticed that the temp gauge was reading higher then normal. I turned the heater on full blast and I was only getting intermittent heat out of it. I switched to the vent and I got the same thing. I noticed that when the heat from the climate control stopped, the temperature reading from the engine went up. When the heat came back on, the engine temp dropped off to a safer level but still higher then usual. I did stop at one point and saw no leaks from any hoses, thermostat housing or the water pump. Anyone have any idea what part of the cooling system is going...and how much it cost to get it replaced Thanks much guys...and gals.
