GM Genuine Parts D1818A (19244505) Engine Oil Pressure Sensor

Works well, no leaks, fit my 2000 Silverado lm7

My 02' Chevy with a 5.3 Vortec started leaking oil. My old oil sending unit worked fine but these have a reputation for eventually leaking oil. The dealer wanted over $300 for a new one installed. I read the Amazon reviews, watched the video's and decided to do it myself. I found this one on Amazon, but the "Will It Fit" tab said that this was incorrect for my vehicle. I bit the bullet and paid $100 for one at a GM dealer. I also bought a sensor socket from Auto Zone which requires a 1/2" drive. Getting the old sensor out was very quick and easy. Getting to it, not so easy. When I tried to install the sensor the top, electronic portion broke. The Auto Zone socket was a bit wobbly and the angle of the drive wasn't the best. Over $100 poorer, I looked at the part number on the box and it was the same as the one on Amazon that said it wouldn't fit. The ACDelco part website also said it was the correct part. I ordered it from Amazon without hesitation. I also ordered the Lisle 13250 socket which takes a 3/8 drive. This drive fits the sensor like a glove. No wobble at all. Buy it. Hoping to get a better angle on the ratchet, I also bought a 10" drive extension which I used with a 6" extension that I had. With everything I needed, it only took about 15 minutes to install the new one. Lessons learned. This can be a difficult, but not impossible replacement to do. Watch the videos. Scraped hands are guaranteed. Hands heal. Great Part. OEM. Buy the Lisle socket. You'll be glad that you did. Try to keep a hand on the socket to keep it seated against the engine. You don't want to strip it. The sensor threads are self sealing. You can use Teflon if you want but don't need it. Tighten like you'd tighten a spark plug. Instead of installing off center from the side, climb on the engine. The 16" extension allowed me to almost be TDC on the sensor with very little angle of attack. It's also easier to hold the sensor this way. You'll also need a drive, angle adapter. If you don't wear gloves during the installation, you'll need a good grease remover for your hands. Verify the ACDelco part number from their website if you have any concerns. Depending on the parts and tools you need to buy to do this, the do it yourself savings can be $250! While you're at it, since you're already on top of the engine covered in grease, replace the PCV valve as well. Your engine and your wallet will thank you.

I bought an unbranded one and the gauge on my cluster read zero. Bought this AC Delco and it worked great.

You cannot go wrong with genuine AC Delco/GM parts for critical engine sensors. I bought this D1818A oil pressure sensor to replace my old functioning unit as a preventative measure since I already had the intake manifold removed for a gasket job. The build quality is excellent, and it comes right out of the box with the necessary thread sealer already pre-applied to the threads, saving an extra step during installation. Once everything was buttoned up, it fired right up and gave immediate, highly accurate dashboard gauge readings that perfectly match the factory specifications. If you are already doing an intake manifold or valley pan teardown on your truck, do yourself a favor and drop this new sensor in while you have easy access to the back of the engine block. Highly recommended!

hasn't leaked in months works perfect

Exact replacement for the Oil Pressure Sender on a 1999 Chevy Silverado with a 5.3 V8 LS. Keep in mind the plastic portion is very fragile. Need to buy the right socket adapter for installing.

Fixed a bad oil leak and this was the problem. Also this was the cheapest place to get the part.

I just had a re-manufactured PowerTorque 6.0L GM engine put in my 2000 Silverado 2500. All the sensors were replaced but not OEM. The oil pressure was significantly lower than I expected and at times did not vary with RPMs as it should. I decided to replace the sensor myself. I bought this OEM sensor and the sensor removal socket. It is a bit tricky to get to the sensor as it is at the back of the engine behind the intake manifold. When I removed the electrical plug from the old sensor it came apart in 2 pieces. After installing the new OEM sensor oil pressure indication is normal and as expected. Always go with OEM sensors!!

The purchase of an original GM oil pressure switch works great. Now the gauge is showing the accurate pressure for my 2002 GMC Sierra 2500.

perfect fit for my vehicle (chevy 1500 HD 6 LTR with a preasure gauge )
