I've noticed over the past 9 months a slow loss of Dexcool coolant in my
2001 5.3 L Tahoe with 60,000 miles. I've had to top off the overflow tank
with about 1/2 quart every 2 months or so.
A local oil change shop said they notice a slight coolant residue below the
passenger-side cylinder head gasket, their thought on the likely site of
Is a leaking head gasket a common thing on this engine? Does anyone know of
a GM tech service bulletin on this matter? I was just wondering if GM will
take any financial responsibility for a head gasket replacement repair, if
that proves to be the cause.
