Trailblazer water pump and fan wobble Fix 

If those water pump bolts go thru that housing it'll be a good idea to use a sealer.

You did a real nice job of explaining things. Thanks.

Yup. The hardest part of the whole job is getting that fan threaded onto the water pump. This is where having patience will save you a lot. The fan should spin on easily. Just like when taking off. If it does not spin on easily or stops after a turn or two... YOU ARE CROSS THREADING IT! Back it off and try again. Patience.

If you have a problem with your TB burning too much gas. Change your MAP sensor. My 2004 was only getting 14.3 mpg. Now it get 15.3.

My mechanics new one for me said 3 hours labor cost 300-? 400 total approx with cheap part he said . Does that sound right ? Everything so expensive these days it’s April 2023 today

That's from a head gasket leak or they put some kind of stop leak in there I had a Ford and I put some stop leak in there and after a while I seen something similar to that

This helped Me so much thank you

Is the tensioner pulley supposed to wobble like that? My trailblazer does the same thing and I read online that it should be wobbly.

How did you make sure not to strip the fan again when installing it? Getting ready to do this repair myself

Thanks buddy good job 👏 👍 👌 🙏✌️

What if the coolant was empty as well as the wobble would there be anything else would need to be replaced or is that normal with this problem?

Should be an auto tech teacher

Did it sound like a jet going down the road too?
