Engine Cooling problem
2001 Chevy Suburban V8 Two Wheel Drive Automatic 117000 miles
We've been having this problem for 2 years now. Low coolant light comes on & resevoir is usually about 1 inch low on fluid. We had the reservoir replaced because the mechanic thought the sensor was bad. Now the vehicle is leaving a small puddle of coolant on the ground. Coolant light comes on & again reservoir is only slightly low. We've been adding coolant about once a month. Took it to another mechanic & they have no clue. Is this the water pump going bad for 2 years now?
