[THawk45]

made a turn and Engine light goes off and No acceleration nor No Boost build, i pop out the scanner and got code P012B so I assume it’s a sensor pop open the hood to see the S Belt snapped in half. (@25k Miles 2018 TH)
Long story short the local dealership is beyond backlogged and said 1 month minimum. I’ve seen recommendations for Greens Belts and ordered one im just scared that possibly the Tensioner could be broken or misaligned. it seems firm and undamaged.
just wanted some advice on if I should Replace my self in order to bring it home and store until the appointment, or leave it at the dealer for them to diagnose everything under warranty?
Any advice is appreciated thanks in advance.

More than likely no collateral damage. Mine snapped as well and I now change it every 15K miles since it's a low cost part and easy to install - gives me peace of mind knowing I am possibly saving myself from being stranded far from home.

Ya I’ve seen a few posts here and multiple ppl said the same. I think that’s smart and already ordered extras, thanks for ur input I appreciate it just want to hear some thoughts

More than likely it’s just the belt. Just pop a new one on and get a spare, then change on a regular basis. You can put a torque wrench on the tensioner and check if it’s in spec, idk the spec though.

You can still drive the TH without the SC belt. Just accelerate slowly. I drove at 50kms without the belt to get home. It drove fine. I even got it upto 80mph without any issues or codes. If it goes into limp mode just restart.

Mine snapped dogging a X5 M. That belt was on for a week.

Same, but I was against and x6m competition. I was so mad because I nailed the launch.

 

[Lil Hemi]

Thanks for the reminder, I just swapped mine out today. I’m on a 20k schedule ever since one snapped.

 

[CAPTIN SLOW]

Damn, guess I should look to swap mine then. 23k on the Jeep and never had any issues.

Might as well. The first one tore up my hood liner went most of it shredded on startup, a new belt is like $45, I just ordered a new spare.

Anyone have the part number?

Anyone have the part number?

There was a thread a while back: Belts

From the thread:

I got real curious about the various part numbers supplied and decided to call Gates today. Here is what I found out regarding the different part numbers.

Gates K100579HD is correct for the TH, but I found out after talking to Bill (at gates.com) that part number K100579RPM is a better replacement option as it was designed for the supercharger stress and is more stretch resistant. ( Again you can decide for your self, as Bill did state this is a replacement option for the HC motor.)

As far as Gates K060846HD, this will fit the TH, but again after talking to Bill, part K060834 will work and is more to OEM specs.

I asked about where to buy and it was recommended to buy from an authorized parts supplier, NAPA, O'Reilly, etc VS. an Amazon. His reasoning was backing up of warranty.

I know that I have priced part numbers on Amazon and O'Reilly, but the little voice in the back of my head keeps saying is the couple bucks worth it vs. being able to go just down the street to the local parts supplier.

I am going to go with the advice from Bill ( the gates tech guy). This is my 2 cents on the subject and again you can decide for yourself.

Well you just threw a curve ball at the which of the Gates belts are better.
Does anyone know what tuning companies are using as the upgrade belt when upgrading the TH?

 

[Lil Hemi]

First I’m hearing about it. So far the HD belt was the upgrade.

[Lil Hemi]

I think I was running the normal gates belt when it snapped, I bought two HD belts after that and just put the second one on (as a precaution).

Is your Jeep modded with a different pulley? I was just looking at your signature and was wondering because that would be an issue for sure as this belt was designed for a stock setup.

I installed one of these on a friends hawk last summer and his is still fine with no issues but his setup is stock.

Not yet, have all the parts though. Been busy with 300 Whipple build.

That was with all stock stuff.

I don’t think I’ve heard of the HD belts snapping. Have a look at the tensioner with the motor running and look at the amount of travel left in the tensioner as the belt moves if it goes to the unloaded side, then I’d say you need a belt, if it bottoms out on the loaded side then I’d say it’s a tensioner issue, assuming you have the correct belt size for your setup.
