I got the Stewart and the GAS cap. I don't ever plan on having an issue. 40k miles so far. Almost time for a coolant flush actually.

Yup, the hose on the aftermarket kit was extremely difficult to get on. And, the metal clip wouldn’t engage properly.
The water pump impeller also self-destructed on the graf(?) unit.
My wonderful wife (who wrenches with me) found this piece sitting just inside the WP housing!!!
I have no idea if there are other bits inside my engine anywhere or not. I had no cooling problems or noises because of it. At 145k now.

That's a metal impeller pump. Looks like the bearing failed and started wobbling in there. The composite impeller is completely different looking. I've had both the OEM and a Bosch metal impeller. The Bosch pump lasted about 40K. The bearing went and started making a racket. I replaced with an OEM pump and it's still going strong.
There's a big following on the internet that the composite impeller fails. This is just not true. Parts suppliers hype it up to sell parts. Composite impellers are impervious to erosion in low PH environments and the are lighter weight which puts less stress on the bearing. My whole cooling system is OEM. At 145K miles, some of the parts are still original like the lower hose and radiator.
My car is super charged and my water pump is under driven and I live in SC where it's hot as hell.... never have had any over heating issue... not even close

Yep, I learned my lesson too.. glad I caught mine before it grenaded itself like yours. I should of known better having worked on pumps for 15 years back in the day... I got sucked into the hype
