Update: I replaced the thermostat and it seemed to fix the issue. And I
will add that replacing the thermostat on this model is a total bitch!!
Two bolts that are easy to get to and one that only rubberman would find
easy. Took me about half a day. On my other cars took me about an hour to
replace.
You have a vapour lock issue. Replace the cap with an OEM part. Run the
idle engine with cap off, let the antifreeze tank overflow and run for
about five minutes and top up when you don’t see any more bubbles from the
antifreeze tank. Recap. Make sure you use the Dex-Cool coolant. Anything
else may cause rust.
See if you have bubbles in the coolant reservoir. If you do, your head
gasket is blown
When u drive the car around then you get out to check it where around is it
coming from lee
just watched ur vidieo i have the same ploblem and fixed it in mins ur
water pump is air locked start car have resovior full losen bleeder screw
till all air is out and antifreeze come out then tighten it u need to
get air out of water pump worked for me and my hose was doing the same as
yours throbing works great now
u also have slow leak in intake gasket but keep resovior full and it will
be fine add to it every few days and bleed air out of punp threw bleeder
its on top of pump a brass little bolt
ps its directly above the lower radiator hose …………….. Im having
similar problems out of my car expecially that upper hose shake and I still
havent figured out how to fix it
Did you ever figure out what was wrong with the car? Because my car is
having the same problem
@Luke Morse, I replaced the thermostat and it seems to have solved the
overheating issue. Now I still have a hard starting, rough driving issue
which I think is a bad fuel pump.
I fixed all my leaks now have oil in overflow, oil on inside of resivoir
top. 3 years ago had leaking intake found out pep boys torqued intake wrong
causing leak.
ioes have a bleeder it red and sits on top a of a hose on the left hand
side tword the of the car……. I am having the same issue i have replaced
the water pump thermostat and the head gasket and spark plugs. At first my
was comming out of the over flow and now it is leaking behind the
tensesoner pulley. cant figure out whats going on. any ideas?
I have 99 Pontiac same engine I revved Eng up to 3000 RPM and heater hose
was leaking going at fire wall only at high rpm. New resivoir is about $37
dollars at autozone
@Crystalwingsa, I’m not aware of a bleeder and haven’t seen it mentioned in
my research online, but of course I still could be wrong. I’ll have to do
more research. I’m not aware of where it could be leaking from around the
tension pulley unless it is coming from the “weep hole” on the water pump.
I know it’s hard to get a good look at those tight, dark spaces.
Unfortunately I don’t have any other recommendations. Good luck and hope ya
fix it.
ITS YOUR INTAKE GASKET!! Gm is vehicles are known to leak in the little
corner of a intake gasket. Trust me, replace it, I just replaced mine and
it is as easy as 1 2 3. Also the air bleeder screw is along that silver
looking solid hose coming off your water housing, Just follow that and you
will see a gold looking screw. That is your coolant bleeder screw.
its your lower intake manifold, the coolent passage on the head closest to
the fire wall would be my best guess
Same exact symptoms here hope someone sees this
It might be big Air bubble in the coolant. Try bleeding the system through
the bleeder screw if you haven’t already.
@04MOJOGT, I don’t think this car has a bleeder screw but I might be
mistaken. I did run the engine with the cap off and re-topped off the
antifreeze as needed. It’s still running a little warm (a little past half
on the gauge) but doesn’t overheat after I replace the thermostat. Thanks
for the advice! 🙂
Had the same issue and it was my radiator cap. About $8.00 at autozone.
What to do now
I actually know where the bleeder is its in the front on top of the engine
its connected to a long black bar that spans across the engine its on the
left hand side(passenger side across from the cooling tank looks sort of
like a door hinge make sure to to twist the screw not the bolt things could
get messy 🙂
