2007 Grand Prix coolant bleeding 3800 3.8L

2007 Pontiac Grand Prix 3800 3.8L V-6 coolant bleeding. 5 mm allen wrench top of thermostat housing.

[@joshsansoucie5074]

I just cleaned out my heater core, changed thermostat and water pump yesterday. Still had no heat, and then I found this hidden gem of a video. Dude, THANK YOU so much for this knowledge. It worked within 20 seconds, you are a saint for sharing this info. I will always remember this, for similar situations. THANKS AGAIN!!!

Great advice on the location of the bleed screw. Another site of supposed professional mechanics that try to sell their advice swore there was no bleed screw and that the system would bleed itself. Well it doesn't - you try that and it just overheats because the hot fluid is never getting to the thermostat with all that air trapped in there..... My bleed screw was in the same spot but was a 10mm socket because it's a 2006 Grand Prix, but same idea. Thanks. You saved me a lot of hassle.

[@larsbambi1575]

I've had an 07 Pontiac for about eight years.. once every 6 months I have to bleed the system.. to find out if you have the problem watch your gauge it will fluctuate up and down over halfway... then turn your heat on hot. If you don't have instant Heat...you have an air pocket in heater core. You can either bleed like shown in this video or sometimes you have to take both heater hoses off spray a garden hose until it comes out the other side.

My 2007 Pontiac Grand Prix 3800 V6 doesn't sound like that. It has about 160,000 miles. But this video has great information, thank you very much. 👍

[@MsJhook]

It did sound like a tractor

[@tswannoc]

Shouldn't the engine be running and the heater on max?

[@mkt45acp]

I replaced the thermostat on my 2007 Buick lacrosse 3800 series 3. I added fluid until the radiator was filled but did not get any fluid out of the bleeder screw. What did I do wrong? Wasn't getting heat, changed thermostat. Car did not overheat before or after new thermostat. I went from a 180 to a factory original 192°

I have the same exact car same color💪🏾🐐

[@tuddyjohnson488]

Y does your car sound like a Tractor..

[@tmeme1836]

where is the bleed valve on 2000 pontiac sunfire gt 2.4L? I need to bleed the coolant system and there is no little metal radiator cap, just the larger reservoir cap. please help?

[@jeremiahtreece8974]

Car sounds like it's about to blow up

[@jebb3620]

stripped out that screw i bought a new housing had rto make sure im doing it right

[@Brett235]

I figured that out today and it works. I'm guessing that's what it's for? I don't know but it works.

[@terryashford7821]

Awesome, let me ask you is there a way to clean the goop out of the cooling system? TIA

[@mikixP]

Does this work for 04 Pontiac Grand Prix supercharged too ?

[@maxfield9873]

Yes, Just did it. Except the bleeder looks like the bleeder on your brakes. Nipple like, y'know?

[@johnvoncolln9110]

Bro is that carpet? Are you in your living room?

[@brentwolfe2661]

The garage floor gets real cold in the winter time. So yeah that’s my old carpet out of my living room.

[@shawnhorne8132]

Did u use the gm thermostat???

[@andrewsalyer5340]

what thermostat you have on there?

[@ricardo08527]

I replaced both fans and after 2 months the driver side seams to not come on the passanger side come on need some input.

[@pootedpooter409]

I have this same issue right now with my 3800 buick lacrosse. Driver side fan will work for like 30 min after starting the car when it's cold and then it will shut off and force the other fan to come on late and at twice the speed. Error code p0480 fan 1 control circuit malfunction. I've tried fixing every electrical thing relayed to it. Fuses, relays, new connector. Idk what to do anymore. Did you figure yours out?

[@ericdixon5160]

HUH? I CANT HEAR YA! LOL

[@mcdavidhome100]

why did you need to change the coolant elbows?

[@eddiekissane3964]

I had to change mine because the plastic ones that come out the factory fell apart going into the water pump

[@braddishner8597]

Common problem with the 3800

[@getreal4883]

@@eddiekissane3964 I have a 01 grand prix changed my elbows this summer was eazy

[@MP-ef6mc]

You obviously haven’t had a Grand Prix very long. Lol. Most common problem on them.

[@mcdavidhome100]

@@MP-ef6mc well 3 years later from asking why did you have to change coolant elbows I found out why. Just changed mine a few days ago. For the longest I was loosing coolant and had no idea why until the elbow completely blew out.

[@TheRichardOlson]

Thanks hoss

[@eugenioolguin7281]

What happened if you don’t take the air out?

[@jj2darepublic275]

Heat won't work

[@nathanbragdon1377]

What is that sensor called right on top of the intake

[@brentwolfe2661]

Not sure. Don't have that car anymore.

[@micahpfeiffer8117]

Thermostat

[@sneperrone]

Just an FYI........you used the wrong antifreeze. You're suppose to use Dex-Cool, which is orange.

[@brentwolfe2661]

It was the universal mix with any color antifreeze

[@ChevroletTough]

no he didn't. dexcool is recommended but that stuff is terrible if not properly maintained. Universal is best honestly.

[@eddiekissane3964]

Dexcool always gunks up on me and destroys the thermostat, I would never use that crap.

[@rickmontalvo9527]

I read the all you gotta do is flush the radiator completely and then use the green one wich is good for any kind of car.

[@jayinla228]

DON'T use dex

[@brentwolfe2661]

Both elbows were cracked

[@Dmkpit401]

sounds like that one been over heated a few time....just a little but like most chevy guys im sure its fixed with a bottle of Lucas

[@tuddyjonson1614]

My 2007 Grand Prix sounds great..Your car sounds horrible..Try changing your oil to 10 40 weight..

[@Tom-ll1fg]

I’m sure the car is long dead lol, video is 5 years old. Car sounds terrible!! I’ve owned 3 3800 cars and never had one this bad.
