OK Thanks.. I looked at the diff ones from RA too... I saw the CAPA certified ones a while ago. Mine aren't too bad, yet
Yeah these are the CAPA ones but I can’t tell a difference. Not sure one is any better than the others. Mine were much worse in person than on a picture. The LED lights were the highlight of the upgrade. So much more light.

Dropped in a new 160A alternator and serpentine belt. Old squeaks & squeals are gone .

I also spent 30 mins with the engine running trying to find the coolant leak. You can see the wet spot in the top left, along the hood seal.

The front of the engine is dry, nothing around the water pump or any hoses that I could see/feel, and the heater core hoses & plastic connectors are bone dry.

The hunt continues ...

IF you are losing coolant in that area, it's for sure the heater hose Tee's...
Get the GM ones, not dorman or other brand.. Kind of a PIA to change, but you'll be
stranded and overheat your engine once they "go"

Dang bro you got leaks everywhere. Valve cover gasket? Brake master cylinder? What the hell is all that fluid all over the driver's side strut tower??

Where's that setting?
Mine will only run for 10 minutes and shut off, and you can only do that cycle twice without having to cycle the key.
In the infotainment.was on 10min It says to change setting hit the check mark?? Then it switches to “on” but doesn’t change when you hit the check mark again? Did a little googling and can’t find it. Now the remote start won’t work??
