GM Genuine Parts 12636175 Variable Valve Timing (VVT) Solenoid

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

bueno i orijinal

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

Just like the originals.

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.

Ordered these for install made appointment with mechanic, went in and he asked me if I was due for an oil change I sold them yes he said can I go ahead and change that oil first? I said yes, he called me up and told me check engine light went off all it needed was an oil change. He said sometimes debris can get caught in the valves of these things with dirty oil and cause them to not work correctly. So I ended up returning them but they were quality AC Delco parts.

Great value, half the price if the parts store, fit perfectly. Car idles like new and increased gas mileage. Had code p0021, gone now. Recommend replacing all 4 of the valves since you have to remove so many parts to get the bank 2 sensors and valves anyway.2014 Cadillac SRX 3.6

Very well built
