90 suburban with 454. 1-13/16 and about 2-5/8 long could not find it on google. most of them are not long enough. thank for any help

 

- about any national parts chain should have one of these on the shelf, or within a 2 hour window if not in stock.

The mfr. part # 25254 should be easily crossed over to any house brand tools they may be stocking - OEM tools is a well known brand in the auto tech world.

Lisle Tools # 13250 is another good option.

 

i bought the sensor from amazon and the socket you mention but the one in the block is 1-13/16 wide.

 

the socket fit the new sensor.but too small for the original one

 

I have a 2014 GMC Yukon with 6.2 liter engine, did this last year to fix mine, it worked.

I used a 27mm deep socket (6-point).

My tip is to tie twine around new sender in case it's dropped while trying to thread it in, then pull twine to break it.

 

seem like no one carry that size tool. the sensor locate at front of the engine just above the oil pan. i have unplug it cause it keep blowing the b+ fuse that power the fuel pump. might have cut it and put a socket on it. thx for help

 

If the switch is actually 1-13/16” then it’s not the typical switch for these engines as the hex is 1-3/16” wide from the factory.

Usually the switch can be removed with a pair of channel locks or vice grips. On some occasions I’ve had to remove the fan and/or shroud to get some swing room.

Also is the circuit for the fuel pump currently bypassed at the switch? If not I was gonna suggest bypassing it just to see if the fuse still blows - if so there’s a wiring problem.

 

I definitely do NOT believe that sensor is 1-13/16". I used a 27mm 6-sided deep socket on our 2014 Yukon, positively.

 

 

Truck runs fine now with the plug off. does not blow fuse anymore. Beside its one of my spare vehicles. Thx for the advice.
