GM Genuine Parts 12636175 Variable Valve Timing (VVT) Solenoid

Quality GM part

Encajan perfectamente. Opción de remplazo excelente

Had P0023 (2012 Enclave) (also had P2099, P0430) engine chugging slightly in OD. Finally SOLVED it by replacing VVT Solenoid (think problem was: I cracked solenoid plastic housing when replacing my alternator). But first replaced Camshaft Position Sensor (see steps below) but didn't get rid of codes so I replaced VVT solenoid after solenoid connector cracked off in my hands when trying to unplug connector to test. Also used liquid electrical tape to reseal connector wires as they were pulled back from connector and showing bare wire. Side note: Did all the following and didn't solve it...ugh: Replaced the Camshaft position sensor & bank 2 lower O2 Sensor... but code came back. Bank 2 exhaust is located just to the left of the Oil fill cap (near top of engine). Unfortunately, it is hidden behind a ton of stuff that needs to be removed to get to it. Heres what it took: Detach negative battery cable from battery. Remove10mm holding ac line near top front. Remove (2) 10mm holding overflow tank (move aside). Remove Fusebox cover. Loosen (2) phillips 10mm bolts (holding fuse wire harness) inside fusebox. Remove (1) 13mm bolt connecting positive battery terminals to fusebox. Unclip and remove fusebox middle part (with fuses) removing wire harness from bottom. Unclip/remove fusebox bottom. Remove (3) 10mm fusebox aluminum baseplate. Unclip wire harnesses from baseplate. Remove (2) 15mm engine mount bolts (holding rubber figure 8 mount). Slide rubber figure 8 mount out sideways. Remove (2) 18 mm bolts from part of mount that bolts directly to engine. Remove (1) 10mm camshaft position sensor bolt. Remove sensor. Detach sensor wire clip. Reverse to replace everything. Lots of parts to remove - it wasn't that bad once I figured it all out but just a lot of little maneuvering to get such a small part out. I would give yourself 1.5 hours (or more) to remove and 1.5 hours to replace. This same/similar procedure can be used to get to the alternator on this car also but I'd also remove radiator hose for alternator and plastic shroud for alternator.

Easy to install, very durable construction, oem quality, and great value for the price

These were a perfect fit! I got these a lot cheaper than going to my local parts store. I was worried I’d have trouble but no worries now. Excellent buy

Just like the originals.

Part well needed. Now I am back on the road.

2/3 sensors purchased were faulty. This was confirmed by a reputable mechanic who removed them and replaced them again with new GM sensors that were locally sourced, confirming that the purchased sensors were faulty. Due to the timeframe of diagnosis and repair, the return window closed before the mechanic could confirm the sensor failure. If you are willing to facilitate a return and refund of these faulty sensors, I am willing to pull this review and leave you with a 5 star review in the name of doing what is right and fair customer service. I was told that one sensor was a complete failure, and the other actually had oil leaking back through it causing it to fail. I do have both sensors in boxes from the mechanic. Thank you!

Australian GMH use the GM 3.0 litre V6 in the VE & VF model until they left Aus. This VVT Solenoid item solved my "intermittent engine hesitation or flutter" problem. Many thanks. (note no fault codes show with this problem)
