Hey Guys, its been a long time. I am currently driving a 98 Buick with the 3.8 V6 and 120,000 on the clock. The car runs 100%, and its paid for
My problem is I seem to be losing coolant, at the rate of about the entire overflow in 2 weeks (I only drive on avg 15-20 miles a day). The problem is I have no leaks. I even went so far as to pull the spark plugs and they all looked good (none of them looked “steam cleaned”). I put florescent dye into the rad, and I can’t find a drop of coolant anywhere. The intake gaskets have already been done on this car, and I triple checked around it with the die.
Rad, and hoses all check out, no dye in the oil, no dye at the heater core/AC drain under the car, the core plugs are fine, around the head gaskets seem fine as well… I CANT FIGURE THIS OUT !! I am 100% losing coolant, but I can’t find hide nor hair of it… ANY suggestions would be appreciated !!
I know I can keep adding coolant, but I like my cars as leak free as possible and if it is something bad, I want to know about it now not later.
Thank you in advance
