During oil changes, I always check the clearance of the lower TMAP wiring and connections in order to assure that there is enough room between the A/C piping and/or compressor so as not to cause abrasions. I changed my oil and filter over the weekend, so I decided to take some pics of it for the group's benefit. I provided some photos of where to jack up the car as well as where to look and what it looks like...








Use the bottom of the coolant reservior as a reference point to locate the sensor.


Clearance is highlighted in red.

Remember that this is a static view of the clearance. Insure that there is adequate clearance to allow for component movement and engine rock under high torque demand.

 

Good information, well documented. Thanks!

 

I'm officially suggesting that ChevyMgr make this a sticky. It's simple and yet effective.

I think mine may be hitting, I just looked and it's up against the bottom of the radiator.

 

I have not done this yet, but was thinking would a motor mount like the TTR one help stop it from hitting since it helps eliminate some of the engine movement?

 

It definitely helps.
