Question: Car overheats but only when stopped like at a
stop sign.

Answer: Make and model vehicle please.

2007 Chevy Equinox. I Changed thermostat but still
doing it.

Did you purge the air out of the system after t-stat


Are there any bubbles in the coolant when running?


What engine size?

Not sure. 3400 v6 i think.
Yes, probably the 3400 engine. A common problem is a
leaking rear headgasket. When this happens, cylinder
compression is forced into the cooling system causing
air pockets. When you accelerate or drive at speed
higher than idle, the air pockets move, so the engine will
cool down. This is sometimes accompanied by no heat
from the vents.

So does that mean that I should change the head gasket
Or get a new motor ?

If a bad headgasket, it would just need to be replaced.

OK, thank you for the information.
Question:  Hi, I'm looking for the heating core inlet and outlet hook up
location on the engine and firewall on my 2001 3.4 Chevy Venture
Van WB edition. I just bought this minivan and I have no heat. The
engine was replaced recently and was wondering if maybe the
mechanic forgot to hook it up. Knowing that when they had the engine
out probably bypassed it to test it when out of body before installation.

Answer: They are located on the center of the firewall, best seen from
under the van.

Ok great. I seen a couple of aluminum pipes fastened to the center
firewall with no hoses hooks on them ( one just bout 3/4"taller then the
other. They look clean as if it was just recently removed so i take it
there is more then one heating core. One for the back as well? It does
have heat and a/c controls for the rear.

Yes, it does sound like those are the pipes.

Well then that semi good news. lol now to find the out and in one the
engine. Would it come directly off the water pump?

No. One pipe bolts to the back of the rear clinder head, the other is
near the thermostat housing.

Is there anyway I can gitt a online picture showing me the inlets and
outlets of the heating system? Sent to my email address?

Sorry, we dont have a pic of those particular things.

Ok. Do you know if I will be able to access the hose. Hook ups myself

Yes, you should be able to. They are formed hoses between engine
pipes and firewall pipe. If you go to a parts store to get those hoses,
they should have a pic.

Ok great. Hey thanks.
