High Temperature Coolant Reservoir Failure

Here's another video. Taken right after a drive. You can see it bubbling right up at the seam.

I waited about 45 minutes after driving for the coolant to depressurize and stop bubbling. Hit the area with some 100 grit sandpaper, then an alcohol wipe, then slapped some high-heat JB Weld on it. We'll see how it does tomorrow.

Spoke with Red Noland today. They did not act too alarmed and said they've seen several leak but have never seen one just outright blow. Ineos roadside assistance could have it towed there to fix, but then I'd be looking at flying there to drive it back.

So, current plan is to just have them do it sometime in late June, early July. I'll be driving out to Colorado around then as I'm having a downhill mountain bike built that I'll be itching to kill myself on.

In the meantime, the temperature here took a cool turn so I'm going to probably wait until tomorrow morning for last night's JB Weld patch to fully cure before I see how my temp fix works.

Looking forward to the update, Ryan. If it holds, it would make sense to build a little kit to handle as a trail-side temporary repair.

I let mine go for six months until I could get to the dealer.

Trailside would be interesting.

The product I used is the standard JB Weld, which is rated for up to 5020 psi and 550 degrees Fahrenheit. https://www.jbweld.com/product/j-b-weld-syringe

The problem is that it sets in 4 to 6 hours, but it really needs up to 24 hours to fully cure. If the temperatures dip near 40 degrees (which it did here last night), it can take longer.

There's also "minute weld," which sets a lot quicker. But I did not see any pressure or temperature rating for it. https://www.jbweld.com/product/minuteweld-syringe

There's also "kwik weld," which cures in 4-6 hours. It's rated for 3127 psi (which should be plenty), but only rated for 250 degrees Fahrenheit. The latter may be good enough, but it's pretty close. https://www.jbweld.com/product/kwikweld-syringe

If you are in the desert or someplace warm, and are planning to just spend the night regardless, the standard JB Weld may work for a trailside repair. If you are somewhere cold, though, you may have to sit a while, or roll the dice on one of the quicker-curing products.

How do they measure the JB Weld PSI rating?
Just curious!
