Losing coolant in my 2000 gmc sierra

Losing coolant...dont see any leaks???

Answer This Question
  • Anonymous Nov 11, 2011

    any steam or excess moisture coming out of the exhaust ?
    Any white or creamy appearance to the oil (pull the dipstick_)
    If so, warped head or failed head gasket could allow coolant
    to pass thru the engine.

These motors are famous for the intake manifolds leaking coolant.Have a pressure test put on the coolant system and look for a leak around the intake manifold corners.Check all four corners i've fixed many of these.

possible thermostat stuck...are you running 60/40 mix in cold temps? oil may be from tranny cooler lines..may have leaked thru to antifreeze..hopefully freezing temp didnt expand walls of radiator and crack it allowing oil in coolant. Cooling system flush recommended

Coolant in my 2000 gmc sierra is disappearing. replaced the water pump a few weeks ago and I do not see a leak. head gasket seems fine as well.
the answer to this requires a pressure test. If it looses pressure, keep looking until you find it.

Leak of antifreeze
This leak is probably coming from one of the 2 coolant lines that feed and return coolant from the heater core. It best be that you get it repaired before you lose to much coolant.
