Thanks CamGTP Ya I was thinking the same. Just wanted to see if anyone used the original as opposed to aftermarket. ive done quite a few over the years also really never had an issue with aftermarket. Sometimes there better than original OEM. Just look at mine not even 60,000 Klm on my truck and its gone. So far Ive had oil cooler lines done valve body in Transmission - power brake pump - rear top light for leaks - shark fin leak - fold in drivers mirror - New exhaust for the adaptive valve flapping around. rear sliding window track leak. plus a bunch of recalls. GM is really making crap these days. Funny thing is the dealer service guys tell you we don`t see these trucks in for much!!! YA OK (REALLY) seriously thinking to sell the truck. i know every make has some issues but it seems every time i have an issue with my truck there`s 100 rd of people maybe thousands all with the same issues.
