Engine Cooling problem
2001 Oldsmobile Aurora Two Wheel Drive Automatic 32000 miles

Have a leak not sure where it's located...could be under, on the side, along the hoses, not sure. A pressure test was done no leak found. Coolant leaks on the floor often.....sometimes a little and other times alot. Doesn't look like a crack in tank. Please advise. I did donate $5.00

Hi there,

Thank you for the donation.

If the coolant is leaking externally a cooling system pressure test should pick it up. you may need to have the surge tank filled to the top and have the system hot so that if a minor crack is there when hot it may expand enough to see the leak, start here.
