So one of the first things we need to do is make sure that we have hand and eye protection. After that, what we're going to do is we're going to remove our negative battery terminal. Set this aside so there's no way it can make contact with the battery. Now let's get underneath the passenger side of the vehicle. Right along the engine, you're going to see your starter. Remove the two mounting bolts for your starter. Let's go ahead and grab onto that starter. Pull it out of the bell housing area where it's situated. Show There we are. Now I'm just gonna use a pry bar. I'm gonna lift up on this tab and just try to get the pigtail off of the sensor. Make sure you have the pigtail clear out of the way. And we're going to spray down the area around that sensor just to help it out, a little bit of penetrant. Now we're just going to use a 10-millimeter socket, and extension, and our ratchet and get that mounting bolt out of there. Hey, it's almost out. Let's finish it up here. Come on. Here we go. Now let's just take our pry bar, carefully try to put it between the sensor and the engine and just try to pry it out. See if you can get it to wiggle and break free. That just started moving. It feels as though it's getting ready to start pulling right out of the engine. That's very exciting. There it is. Just go ahead and clean up that hole the best you can. Just be careful not to force any of those rust flakes in there. So now we have our new sensor here. I always like to coat the seal with something. You can either use a little bit of engine oil, maybe a little bit of dielectric grease, just something fairly thin just to help lubricate it and help it work its way into that engine block. Let's get the sensor up in there. When we put this in, you want it to go in as straight as possible. Line up the bolt hole on the actual part itself, with the bolt hole on the engine before you go into far. I was going to give it that little spin before I go in any further. Now that we shook that around side to side, wiggled it back and forth a little bit, and got it to go all the way in so it's up against the engine block the way it needs to be, we're going to go ahead and put our bolt in. I'm just going to start it right on the socket with my extension because it's easiest for me to get my hand in there and then we'll start it in and snug it right up. That's pretty much bottomed out. It's going to give it just a teeny bit more. That's good. Get our tool off of there. Let's go ahead and get that sensor back on. I'm just going to line it up and then I'll press it in with my pry bar or something that reaches here. Make sure it's completely latched in and it's not loose in any way. So I can get the starter back lined up with where it needs to be. Start in our two bolts. Snug these up. Let's go ahead and torque these to 37 foot-pounds. Just take a quick peek around, make sure we didn't accidentally disconnect anything such as, maybe, a sensor of some sort. If everything looks good, let's get back up top and reconnect that negative battery terminal. All right. So that was a lot of fun. Now let's get back up here and get this negative battery terminal back on. Make sure it's nice and tight. Give it a nice wiggle. That feels great. After this, what you would want to do is start up the vehicle, let it run for a little while, and make sure that the check engine light does not come on. 2003 - 2005 GMC Savana 2500 Van 2003 - 2007 GMC Savana 2500 Van 2005 - 2007 Chevrolet Express 3500 Van 2003 - 2007 GMC Savana 1500 Van 2004 - 2007 GMC Savana 3500 Van 2003 - 2007 GMC Savana 3500 Van 2001 - 2003 GMC Sierra 1500 HD 2001 - 2003 Chevrolet Silverado 1500 HD 1999 - 2006 GMC Sierra 1500 1999 - 2000 GMC Sierra 2500 2001 - 2006 GMC Sierra 3500 2003 - 2007 Chevrolet Express 2500 Van 2003 - 2007 Chevrolet Express 1500 Van 2003 - 2007 Chevrolet Express 3500 Van 2001 - 2006 Chevrolet Silverado 3500 1999 - 2000 Chevrolet Silverado 2500 2001 - 2006 GMC Sierra 1500 1998 - 2002 Pontiac Firebird 2003 - 2006 Isuzu Ascender 2004 - 2004 Pontiac GTO 2000 - 2006 GMC Yukon 2003 - 2007 Hummer H2 1999 - 2006 Chevrolet Silverado 1500 2003 - 2006 Chevrolet Silverado 1500 2000 - 2006 Chevrolet Tahoe 2003 - 2004 GMC Envoy XL 2003 - 2005 Chevrolet Trailblazer EXT 1999 - 2004 Chevrolet Corvette 2002 - 2006 Cadillac Escalade 2002 - 2005 Cadillac Escalade 2002 - 2006 Cadillac Escalade EXT 2003 - 2006 Cadillac Escalade ESV 1998 - 2002 Chevrolet Camaro 2002 - 2006 Chevrolet Avalanche 1500 2003 - 2004 Chevrolet SSR 2004 - 2004 Buick Rainier 2005 - 2007 Saab 9-7X 2005 - 2006 Pontiac GTO 2005 - 2006 Buick Rainier 2001 - 2004 Avanti II 2005 - 2006 Pontiac Grand Prix 2005 - 2006 GMC Sierra 1500 HD 2005 - 2006 GMC Envoy 2006 - 2006 Chevrolet Trailblazer 2005 - 2006 Chevrolet SSR 2006 - 2006 Chevrolet Monte Carlo 2006 - 2006 Chevrolet Impala 2000 - 2006 Chevrolet Suburban 1500 2000 - 2006 Chevrolet Suburban 2500 2001 - 2006 Chevrolet Silverado 2500 HD 1999 - 2004 Chevrolet Silverado 2500 1999 - 2004 GMC Sierra 2500 2001 - 2006 GMC Sierra 2500 HD 2000 - 2006 GMC Yukon XL 2500 2000 - 2006 GMC Yukon XL 1500 2005 - 2006 Chevrolet Silverado 1500 HD 2007 - 2007 Chevrolet Silverado 1500 HD Classic 2007 - 2007 Chevrolet Silverado 1500 Classic 2007 - 2007 GMC Sierra 2500 HD Classic 2007 - 2007 GMC Sierra 1500 Classic 2007 - 2007 Chevrolet Silverado 3500 Classic 2007 - 2007 GMC Sierra 1500 HD Classic 2007 - 2007 GMC Sierra 3500 Classic 2007 - 2007 Chevrolet Silverado 2500 HD Classic 2004 - 2005 Cadillac CTS What are the symptoms of a failing crank sensor?5 Signs of a Failing Crank Sensor.
