Over heating while driving

Asked by Guru9YP6T8 Feb 09, 2021 at 07:59 AM about the 2002 Chevrolet Impala FWD

Question type: Maintenance & Repair

While parked and idling I’m getting heat in
the cabin soon as I start driving at highway
speed I get cold air in cabin then it over heats
and sometimes when heats comes out the
temperature meddle fluctuates hot to cold
while driving I’ve changed the small hose just
above the water pump that originally bursted
while driving down the highway then I
changed the thermostat and radiator cap
where I seen anti freeze coming with doing I
keeled trying to get air bubbles out I’ve been
stuck in truck stops adding anti freeze and
water the at one point I noticed coolant got
higher in the reservoir tank this morning I’m
thinking I have faulty thermostat. I’ve also
added head gasket sealer and radiator sealer  
see no white out the exhaust and no milky
color in the oil or reservoir tank what else can
I do lol

The problem may have been a bad $7** P.O.S. thermostat , try and get OEM parts so you can eliminate the bad part problem Or even an air pocket ,. But now you've added a bunch of crap into the system and until it's flushed it won't work right , unless the head gasket is blown that's a whole nother thing .
