04 trailblazer overheating
Ok a few days ago I notice my trailblazer was
running a little hot. I found a leak around the
water pump and replaced it. I flushed the
radiator and removed any air bubbles, checked
for leaks and bad hoses. I fixed all visible
problems. It still ran hot (not all the way in the
red zone. About 215 degrees). I then removed
the fan just incase and replaced it with a high
performance fan. Went down the road and
again, it ran hot after about 15 minutes. I
removed the thermostat and tried again. And
again't, it ran hot. Next I bypassed the heater
core, removed all air bubbles, checked the
hoses again, checked for a faulty water pump,
put high millage coolant and purple ice in the
radiator. And it ran hot again . I've had the
head gasket checked, oil level checked,
transmission fluid checked. I have no dang
clue what to do next! It cools off when I'm in
motion but as soon as I stop at a red light the
temp creeps back up. It seems to get hotter,
faster when I have the brake pressed at a
stop. It still runs hot in (P) but not as quick as
it does when it's in (D) at a stand still... And Im
sure the Guage isn't faulty because it bubbles
and boils out of the reservoir. I'm lost!
