12655420 12655421 Intake & Exhaust Camshaft Position Actuator Solenoids For GM Chevy Malibu HHR Buick Pontiac 2.0L 2.2L 2.4L

Just An FYI about these actuators. Warning I wouldn't buy them!I installed both in my 2012 Equinox due to check engine for bad exhaust actuator and decided that I wouldn't have to mess with them for years. Right after replacing my car started the surging problem (check engine light gone) when at a stop with the brakes applied and it was really bad at times. I cleaned the TBI unit and still no change. I installed a complete new set of these same actuators 1 month later under Amazon defective parts and still no change with surging problems still happening. My wife (nice wife power!) and I talked and talked about it and decided the surging only started after these were installed. I order the OEM GM exhaust actuator and pulled the 2nd bad pair out. Installed the original intake actuator that was still good (I had luckily kept it) and the new exhaust actuator OEM GM that I had ordered. Shazam!!! SURGING PROBLEM FIXED and no check engine light. Sorry guys best to stick with GM OEM and pay the price for no more problems!

bought these october 2017. replaced as a set.2 years and 40k miles later still working fine. no surging or engine lights

Perfect fit for my 2006 Pontiac Solstice (non-GXP); resolved check engine light for exhaust camshaft position actuator error. Replaced intake at same time for preventative maintenance. Around a 5-10 minute job (if the original parts aren't frozen to the valve cover like mine were...)

Used these to replace the stock ones on my Chevy HHR SS with the 2.0 LNF engine. Worked like a charm! Easy job once you pull off the air box on top of the engine. Had a code for the exhaust side but picked up this pair and did both of them.Be careful not to over torque the bolts and you should be golden!

Product had the look and the fit, bit unfortunately did not fix my issues with trouble codes and poor idling. Dealer recommended getting OEM part. No more codes and smoother idling now. Was hoping these would work as they are obviously cheaper than Original GM parts.

One did not work and one did after hours of pulling our old and new found out the new one was bad but the old one was good so the check engine light is out now and that's all that matters wasn't easy to find out how to return so I just kept it and put old one in

Cobalt check engine light came on..used a scan tool and found these to be the issue. They were half the price as OEM parts, but seem to work well off the gate.

I have put two sets of these in the auto parts stores $100 apiece for them not had a problem with either car since putting news in
