Coolant leak?

Asked by Feb 26, 2017 at 09:19 PM about the 2003 Chevrolet Silverado 2500HD 4 Dr LS 4WD Extended Cab SB HD

Question type: Maintenance & Repair

I have an 03 2500 HD 6.0 V8 with just a little over
a100 thousand miles. I had the water pump and
thermostat replaced. I'm still having an issue with
coolant smell. Can anybody help. The shop
seemed to  think that it might be a pinhole in the
heater core. Anyone?

If you smell inside the cab, then yes, I would suspect the heater core.
