GM Turbo Upgrade - How to Check Lower TMAP Wiring
 
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.

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?
