COOLANT

1996 Volvo 960 • 6 cylinder FWD Automatic • 137,000 miles

I have a 1996 Volvo 960 Station Wagon with 137,000 miles on it. Great car! However, I have had trouble keeping coolant in the coolant reservoir lately. If I fill it to the fill mark, and run it like 10 miles, almost all the coolant is gone and I have to refill it. It disappears fastest if I stop and start the car frequently. If I fill it again and let it sit like overnight, a lot of the coolant is gone. I have checked the reservoir itself and it does not have a leak--even ordered a new one which should arrive soon--the hose going to the radiator doesn't leak, and there is no sign of the radiator itself leaking if you look under the car on the ground. I am mystified. Where is all the coolant disappearing to and what could be wrong? I have had this car since April. It did seem to use a little coolant, but now it uses a lot. I have always used Prestone 50/50. Please help.

Have the cylinders compression tested. Suspect headgasket failure?

COOLANT SYSTEM NEED TO BE PRESSURE TESTED
ALSO CHECK INSIDE THE CAR AND UNDER THE FLOOR MATE IF WET
CHECK OIL AND IF MILKY
CHECK TRANNY FLUID ALSO IF POSSIBLE
