2002 Chevrolet Corvette Z06: Coolant Leak Fixed
February 17, 2011
The culprit? A crapped-out water pump.
When Bothwell first attempted to replicate the drip, of course, the sucker wouldn't leak. They pressurized the cooling system with the engine off and cold. Nothing. Checked it while warming up. Dry. Then ran it up to operating temp and pressure and checked again. Wouldn't leak a drop.
They called me up to double check the conditions during which we observed the leak. It was always after a long period of running. So they left it running for a good long time where it could fully heat soak. Then the river finally started flowing out of the pump, the accessory drive belt slinging coolant all about and generally making a mess.
Our pump had 57k miles on it. According to Bothwell, it's not unusual for them to see Corvette water pumps give up the ghost at this point in their lives.
It was about time for an oil change so we had them perform that, too, while they were in there.
Once again, dealing with Bothwell was a smooth, professional and courteous experience . The repair did however take about a day longer than expected since they were down two guys at the shop on Friday and had a full house. Seems we're not the only ones to discover a good shop.
Total bill including pump, 2 gal Dexron coolant, seven quarts of synthetic oil & filter, labor and tax- $601.86
