Thanks for sharing !!! Saved my ass, could not figure it out. HEY? ANyone
else having a problem finding th right belt for a 1990 GMC ?? Computers &
manuals say 947, or 945 (inches long) but these belts frayed to shreads and
ripped the PS pump bracket off the block. REALLY MAN! Snapped off two
bolts. Finallly to avoid theprobs. I went to a 950 and everything is nice &
quiet now. THe NAPA & PEP boys computers all gave me belts to short. Using
my VIN even. I’m so curious what happened
Remove the tensioner from the mount. Lay it on a flat surface facing up.
Pour just about an ounce of light oil . Let it sit for about ten minute s
and then spray some liquid wrench around the seam where the spring is.
Re-mount and then reapply your tension on the belt. Worked for me!
No the serpentine belt doesn’t affect the brakes on your Surburban. Some
things you will want to look at is your master cylinder, see how much brake
fliud you have in it. If it’s low go buy some DOT 3 Brake fliud. If the
master cylinder is full something else is wrong and you should see a
professional mechanic.
I think your belt is on wrong.. I have the same truck and yours, the way
its routed around the PS pump looks strange…. Its a straight run from the
PS pump to the alternator.
i have a different belt tensioner. it uses an 18mm on the top and a 15mm on
the bottom pulley. i cant get the belt off and there are no videos on YT
with my setup….i have an 89 C1500 with a 5.7. the belt tensioner needs to
be replaced cause it makes a very annoying screeching sound when i drive
and idle.
Sometimes that’s the price you have to pay. Good luck with it. And those
Chevy trucks are tough as nails. I have a friend that has 260,000 on her
GMC 1500.
good job ya did i had to do this on my truck 3 times its a 93 chevy first
time the idler pulley busted put it back together and the belt came off and
busted my water pump broke the studs etc new belt was 17 bucks but water
pump was 29 bucks mines a 4.3 looks like that one has a 4.3 as well chevys
for life
I could of gotten it cheaper if I would of shopped around. But I needed the
truck operational in a hour, so I bought it at Napa and paid through the
nose.
You do not need to remove any “water pulley studs” to replace a fan belt!
Simply feed it in between the balancer and water pump as per diagram. It
goes on without any fan removal.
I noticed that your truck has the same “bulb test” wiring flaw as many
older GM cars from the 80s. When you crank the starter, instead of testing
the overheat idiot light, it pegs the temperature gauge instead. I had no
idea vehicles as late as 1994 still had that bug. On some cars it causes
the needle to become inaccurate (because it gets torqued every time it hits
the stop) and in some cases it falls off. Yours seems to move slowly
though, so maybe it has some dampening to prevent that.
the tensioner was something that threw me thanks for the video. my mechanic
wants 400.00 to put a new alternator. 85.00 for altenator 35.00 for a new
belt. I,m saving 315.00. thanks again.
My alternator quit a week or two ago. This is how bad my serpentine belt
was: it broke when I went to take it off! I was lucky though, my belt only
cost $16. The alternator was $130 though. Ouch.

This video was uploaded on my birthday haha.
Thats the tension pulley not the idler

No it did not. What is bad is AC pulley. That is what makes the whining
noise my subscribers so often hear from my truck
Good lord, $40? Wow. I really need to change the one on my Pontiac, it’s
all cracked and dry….
yeah now the gauges are going bad when i stop they are acting like they are
on drugs and bouncing all over the place

I take it you corrected that before you started the truck?
what is the right way for the belt to go on ? where can i find diagrams??
Good & to the point!!!! Best thing about this vid is it shows you operating
the tensioner
I just used this video to replace my belt, thanks!
Thanks!

My alternator gauge does that as well!

Damn, you had a bout of bad luck with that truck! Glad to hear you got it
back together.
Is your volt gauge right if so what kind of alternator are you running I
need the same one
i cant get the tensioner pully off the bearing busted inside and the bolt
is stuck on there still any tricks???
Sorry, I don’t know any.
Sometimes that’s the price you have to pay. Good luck with it. And those

Or I could use bar for leverage so I dont smash my knuckles like I am a pro
at doing -__-
Glad my video was help to you.
Good dependable rock solid Chevrolet.
Did replacing it make it any quieter?
the way the used to make em ah
Sounds like the fan is hitting the shroud
does the sepentine belt effect the brakes i think thats the problem with my
93 chevy suburban thanks
I got the same CB in my truck also.

I’ve never changed a serpentine belt before… I just did it in about 5
minutes after watching your video. Thanks!
You’re right, I’m wrong. Maybe one day when it isn’t so damn cold outside
I’ll change it. Still works like it should, however.
My alternator quit a week or two ago. This is how bad my serpentine belt
was: it broke when I went to take it off! I was lucky though, my belt only
cost $16. The alternator was $130 though. Ouch.
The trick using the two wrenches to install the belt really helped getting
the belt easy. thanks for the tip. 🙂
