Pacific Performance Engineering 119022200 PPE SILICONE UPPER & LOWER COOLANT HOSE KIT 2006 2007 2008 2009 2010 GM 6.6L

A few purchases of PPE products now, and the quality is above expectations. There is no drain for coolant on 2008 3500 HD, and I was quite nervous as I was preparing to stab a hole in my perfectly fine hose assembly to be able to capture the old coolant, not sure the new would fit properly. Whew, perfect fit of all the parts I bought. The HD green serpentine belt and tensioner/ idler pulley kit also was perfect fit and great value. Thanks for being a great American Company. Fair price and high quality are hard to find and you guys nailed it.

So far so good, had to do the water pump so while I was in there I decided to get this hose set. Seems very well made and has held up for 3 months and 3k miles, idling, road trips, pulling a 7,000 pound trailer...all good and it looks good as well.

This is my first PPE product and I can say the raw quality is superb, but the fit and finish is so-so in my opinion. The majority of the provided hose clamps were misplaced, (tightened down) hanging over the edge of the silicone hoses, so I had to loosen and rotate/replace almost all of them in the correct place. The biggest problem was that the notch on the inlet for the radiator (pictured) wasn’t placed even remotely close so I had to pry off the coupling, causing shavings of aluminum everywhere from damaging the billet coupling, generously lubricate it then re-insert it into the hose. If everything was in the correct place to begin with, it would have taken me half the time to install this product. Overall it is holding up well though.

Great product fit as advertised

Looks really good and my engine runs a lot cooler and more efficiently.

Every day you go outside there’s a pile of antifreeze the hose clamps are junk the quick release is junk it’s all junk do not buy it , they will not refund you or help with anything they tell you to contact ppe there fire again junk

The hoses seem to be good quality. The fittings seem good too, except the one that fits the lower radiator connection. It took approximately four hours of sanding and fitting to get the aluminum fitting on the radiator. I am not sure if the fitting was simply machined out of spec, or if the o-ring was too hard, or both. The hose clamps were also not the ones in the picture, but the seem to work. Some hose trimming is necessary to get the hose to fit properly. I don't see any leaks, but it has only been installed for a week. If you want a quick and easy install on the lower hose, you should probably go for a stock replacement instead of this product.
