Problem with my 2005 Chevrolet Cavalier
2.2L Ecotech
GM tech = kk
question = I have a 2005 Chevy Cavalier it has been overheating. My temp.
gauge has gone haywire. My cooling fan has not been coming on. My upper
radiator hose gets hot. The lower hose stays cold. I have already changed
the thermostat. Can you tell me what I need to do to fix this problem.

Answer: Assuming you have owned the car for some time, then you know it
is getting too hot.A plugged radiator could be the cause, as well as air in the
cooling system. After changing the t-stat, if there is air in the system, it may
look like there is no change to your problem, when infact the t-stat may have
fixed it. The cooling fans not coming on could be a blown fuse, bad relay,
bad fan motor, temp sensor, PCM, etc. Many things can cause the cooling
fans to not come on. That would be the circuit to look at first.

1989 Chevy Cavalier Z24.
Engine size: 2.8L v-6.
Replaced radiator hose,split. Removed t-stat and ran engine. Still overheating
Question: Should I try replacing the water pump? There has been no sign of a leak except the broken
hose that was replaced. I am also not getting any heat inside the car even when it was overheating.

Answer: First of all, you should not run an engine without a thermostat
because it will not allow the engine to get to operating temperature. If
you've got a new thermostat, install it and go from there. If you still have an
overheating issue, it could be a water pump. The vanes on the water pump
impeller corrode over the years and end up not pumping any coolant
through the engine, so that is something to check. If you have an extreme
overheating issue, there's the possibility of head gasket failure, warped or
cracked cylinder heads, etc. Since you have no heat inside the car, there
could also be a restriction somewhere in the coolant passages or heater
core. You can get a cooling system tester that pressurized the system so
you can check for leaks. If you lose pressure and see no external leak, the
coolant is going elsewhere, like inside the cylinders or dumping straight into
the oil pan. Lots of things to check for this issue.

Question = My car kept was leaking antifreeze and had keep refilling it with water. So i put radiator
stop leak in it and it quit leaking for a couple of days but then started leaking again but not as fast
as it was before i put the stop leak in. I need to get this fixed before winter. Any suggestions?

Answer: Yeah I would say that you definitely need to get that fixed before
winter. One thing too, I would NOT recommend just adding water when you
top the cooling system. As you lose antifreeze and just add water, the
boiling point of the mixture drops more and more and the chance of
overheating the engine becomes more likely. I also do NOT recommend
using stop leak products because they gum up the cooling system and
just cause additional problems. What ever you have leaking needs to be
fixed as soon as possible, whether it be the water pump, radiator, head
gasket, hoses or heater core, it needs to get fixed soon! You need to
have a pressure test done on the system to find the leak.
