Loud high pitched Squealing: 454
Power steering pulley good. Not a vacuum leak. It's one of the accessories. Doesn't sound like water pump. Changed a/c for a dummy pulley and noise still there. Going to change smog pump for a dummy pulley and see if that's the culprit. The mechanic in town said he has never heard a noise like...- SierraDully

Loud high pitched Squealing: 454
I have a loud high pitched squeal from my big block. I'm thinking it's the water pump going out but I just wanted to get some opinions first. First thing I did was put in a new serp belt. That did not change the squealing sound. It almost sounded like a vacuum leak at first. Checked...- SierraDully

454 serpentine belt not aligned to water pump pulley
I was thinking of tweaking the powers Steering pulley to try and line up the belt better but that doesn't seem to be the cause here. I think it's water pump positioning. Here's a pic top down where you can see the water pump -below the belt that travels between a/c compressor and belt tensioner...- SierraDully

There's a pic of the water pump to crankshaft pulley section of the belt. There's a small white speck in the pics. ThAts an ash that dropped off my cigarette. To...- SierraDully

Power steering pump(s)
So, the small block Yukon blew it's original 1997 p/s pressure line in June. Replaced it with a Napa pressure line. That was my first mistake. The Napa line was made from cheap rubber and sprung a huge pinhole-style leak ( like a fountain of p/s fluid all over the engine bay. The old lady was...- SierraDully

93 4L60e to 4L80e
I have to agree with TylerZ281500, it's asking for trouble if you don't know what you're doing. I've had a few customers come in the door looking for driveshaft work. That's coming in the door of a structural steel fab shop. Ive turned most away. Only do the ones that customers agree to the...- SierraDully

Should i try ethonal free gas?
Around here (Alberta) I'm Almost certain the only was to get ethanol free as is to buy premium gas. Thats around $1.25/litre and regular is .93/litre. Any cost savings on fuel consumption or repairs is more than offset with a ~30 cent difference per litre. For my American friends that's...- SierraDully

Vortec 454 Revs up high then dies HELP!!
You can get MAF, IAC, TPS, etc. Readings from a $30 Walmart odb2 reader. it only gives freeze frame if there's a code, but you can monitor it through "live" data (not really instant data, but better than guessing) and always take a pic or vid with your phone if need be. I know it's not as...- SierraDully

Suggestions for trailer brake wiring
What I've always used is just a home made pigtail adapter that will plug into one trailer connector and have an output of the other type of connector. So if there's a round style male connector attached to the truck then I would make an adaptor that has a round female style plug on one end, 6"...- SierraDully

Guide me in front suspension service, 99 Sub 4wd
Stabilizer bar end links commonly break off at the studs and make a sound like you are describing as well. Front ends are weak on obs 4x4's. If it's new to you, probably best to check over everything. Before you take the front wheels off, check for movement in both directions will help...- SierraDully

Look at my oil leak.
I second that. I've pulled a few oil filter adapters off older 5.7's that don't have the cooler lines and they fit right up to the oil cooler line version. Nice simple factory equipment way to delete the oil cooler lines as they will continue to go bad unless you replace with the nice stainless...- SierraDully

96 Tahoe vibrating at speed
Are you 100% sure you didn't lose a balancing weight from one of the wheels? Or could you have a bad tire? Even brand new tires are sometimes bad from the factory. Easy to rule that cheap stuff out first before you start throwing parts at it.- SierraDully

Stainless trim
Hey all...I'm looking to buy some stainless trim for my gmt400 pickup. Would like to find the lower and upper pieces plus fender trim. This is my 97 Yukon. It's exactly the same as what I'm looking for. It was already on the truck when I got it a few years ago. If anyone knows where I can order...- SierraDully

93 4L60e to 4L80e
Yeah I've heard of guys reflashing the same computer to do the 60/80 swap. They were the newer obs odb2 computers. I've never seen it done on the older ones but thy doesn't mean it can't be done. I'm almost sure it can. I've only had experience doing the swap with a kit. Did you get the...- SierraDully
