2.5 4 cylinders, cluster swap

[Fredo]

So, I have an issue, I swapped cluster on my 2.5 4 cylinders, to the cluster that has a TAC. But when changing the temperature bulb/sensor, this bulb/sensor does not fit the bulb for the 2.5 L seems to be shorter than the 4.0L.

 

I had swapped cluster in my 4.0L and no issue.  Anyone knows what temperature senor a 2.5L needs so my gauges can work

 

Picture is the temperature sender I used on my 4.0L

its an 86

Ahhh yes the year changeover. That’s why your having issues. 
Theres two temp sensors used for 86 and it’s all dependent on the head the 2.5L has and seeing how the later 4.0/2.5L won’t fit, you’ll need the older one. I’ll get a part number this evening when I get home.

Part number 1 J3242662 or drop the J for better interchange if needed. 

Part number 2 8953004981. This one says it’s for the 4.0L which could be 87. 
 

88 and up has 53005309. 
 

i think it’s gonna be the J number. If not probably the old AMC number at the second part.
