Question about 2003 Chevrolet Trailblazer Ext
I feel it still is not fixed properly. should I still be able to smell antifreeze?
Ever think maybe one time at that shop was enough?
In 49 years-- I only had one water pump fail a couple
months later & I suspect it was a bad rebuilt part
We can see,look or smell from the internet-- so
find a 30 years old family shop that knows how to
repair your issues

SOURCE: Heater Core Leaking
you could quick fix! but you will have no heat, 1st under the hood, look at the back of motor, follow all you're radiator hoses, take two hoses off the heater core stick a pipe that is big enough then clamp the pipe down. to both sides of hoses to the pipe you will eventually have to replace heater core!!

This is definitely a heater core issue, but I might also suggest one of the many over the counter cures first before replacing it, the heater core is not a very expensive part but quite a chore to replace.

check oil and make sure you do not have coolant mixing in with the oil if so then it is your intake gasket mine has done that twice

Usually a smell of antifreeze in the cab when the heater is running is a sign the heater core is leaking. Just becasue you dont see a leak at this time doesn't mean there isn't one. It might small enough that the haet from the core is burning off the leaking antifreeze. I would suggest replacing the core before you get in one day and there is a puddle on your floorboard. Or if you go to a local parts store and rent a cooling system pressure tester, wait until the vehicle is cold, pressure the system to 12 lbs and then check for leaks. Hope this helps you out......

Testimonial: "that is what i also thought, no puddle yet, just waiting. I tried a sealant for now, but will get a heater core"
Hello... The thermostat is located, as you are standing in front of the car, facing the engine. Swing around to the right side (drivers), still facing the engine. With the Air Filter assembly removed, look at the engine below the throttle valve (the item were the throttle cable is connected). You should see at least one of the 2 bolts holding the thermostat housing to the engine.
It's not in an easy place but with a couple parts removed removing it is not hard.
