GM 3.1 Thermostat Replacement For Buick Century, Chevy Malibu and Lumina, Pontiac Grand Prix SE

[@kenhill3230]

I had to do this on my 2003 Century yesterday and it was no fun. The video is very helpful and well done.My cousin helped me because I could not get the throttle body off. This car is my baby, but whoever designed the stud bolt at bottom of throttle body is pure evil. Getting the cap nut off is easy, but getting the back nut to loosen the bolt is hard. I don't know if they are all the same, but the bottom bolt on the thermostat housing does not have to come all the way out on mine. It is a slot where you can loosen the bolt and slide the housing off.

This is a good step by step video. Others just show part of the process, very detail counts.

Thank you for the positive feedback

Change the thermostat on my "99 Century once. Time to change it again. Came to this video to see if the GM thermostat Wrench was being used on the housing. I see that the housing was put on the same way I did mine before. A wrench and another tool to hold the nut in place while turning.

Thanks for showing this. At first glance I thought I'd have to remove the exhaust manifold which seemed like bad design. Helpful video although the last 15 minutes could have been sped up or cut out altogether for the sake of brevity.

[@RickyRepair]

Thank you for watching! I’m thankful if I helped in any way

[@FelixM-v6u]

Why did you have to remove all that other stuff that's not even around the thermostat?

[@RickyRepair]

It’s often easier and faster to peel it back in layers rather than try to attack directly

[@xaviierrbenz9757]

I did this step by step and now the car wants to start but doesn’t stay running ?

[@RickyRepair]

I’d probably be making sure that you installed the throttle body correctly! Good luck 🍀

[@suddenturnforthebest2282]

I agree I'm sure it's a vacuum hose u messed with or a gap where u hooked back up the throttle body, something like that

[@Hendrixx502]

Do you have to unhook the battery

[@RickyRepair]

Always a good idea

[@ryans413]

You can do it without removing the throttle just a little harder

[@RickyRepair]

I’ve never tried it that way, because the throttle body is pretty simple to remove

[@pearljones859]

I was just about to ask can I just remove it without removing the throttle body. I have a compressor with a rathet attachment that can reach the housing fairly easily

[@kerrypence4201]

Yes easy to remove the throttlebody and it gives you a chance to clean it. People never think of cleaning their throttlebody.

Better camera angles please 😢

[@lusiphercain887]

That's exactly what I was thinking. We see his arm more then what he's working on

[@stevewinter8928]

Stationary videos just don't work very well you can't see anything going on it's just a talk video

[@RickyRepair]

I need to work on it!

[@phxws13]

Doing too much. unnecessary removal of some parts

[@RickyRepair]

@@phxws13 I really have to disagree. As a mechanic, I’ve learned that a little disassembly up front pays dividends. Though it might be possible, is it easy, fast, etc? Struggling through is the parts changer mentality.
