Question For a few months the coolant reservoir would require refilling with no signs of any leakage. I do not have any type of link under the dash, yet the car never ran hot. The temperature was always just below the half way point on the gauge. I recently had a new tank and thermostat installed with what appeared to be the cure-all. Now periodically the coolant reservoir gets pressurized and antifreeze / steam are forced through the top of the reservoir. Of course this is a random event. It occurred a couple weeks ago after a 3 hour trip. I filled the tank and all was fine until yesterday afternoon. The temperature gauge is still normal, but when I stop after a 15-20 minute drive the tanks leaks from the top.
Any thoughts would be appreciated!
Thank you,
Tom
Answer Tom,
So after running for 15/20 minutes it will blow coolant out of the tank. That tells me when the engine heats up you maybe pushing compression into the cooling system. That would mean a bad head gasket or warped, cracked head. Now are you sure that the tank itself is not cracked and just the hot coolant expands the crack and leaks? If you are not sure see a Volvo shop for some help.
