I have 2000 GMC Sierra 1/2 ton, 60 000 km and it just turned into winter a
week ago or so.
I feel that the heat is builing too slow, slower than it used to in previus
winters, (4 of them so far).
The temperature gauge is claiming up to about 95 deg, but I feel it takes
much longer as it used to do, and not much heat comming out initially. I
feed that I had hot air almost instantly before.
I changed oil and all the filters yesterday, including the passenger
compartment filter, that is the 3rd time I changed the cabin filter, so it
is not plugged.
The temp gauge does go up to the same level as it always does, so I do not
think it is a thermostat problem
By the way I was looking yesterday where the thermostat is on this engine,
(4.8 l V8), I think it is different that the old vehicles, did not look too
long for it, but I think it is on the water pump on the return hose from the
Any thoughts on this?
Is this a problem or it is just me getting too old?
