Anyone have the part number for the temperature sender that screws into the bottom of the radiator? Going to be replacing the radiator soon, as well as the hoses and a few other things, might as well replace it while I'm in there.

If I'm not mistaken, there are two sensors, one for the gauge and one for the ECU... not sure if both sensors are the same part number.

Thanks.

 

If it ain’t broken don’t change it. If you do need to replace it down the road, (unlikely) it’s a quick change. No need to remove the radiator.

Agreed don't replace it unless you have a problem.

edit - here's the part number in case someone does a search
89428-21010
Most auto parts stores have an aftermarket version for a lot less.

 

Ouch, that is a spendy part. Yeah, will leave as-is.

Thanks for the replies!

 

+1 your radiator is more likely to fail than that sensor. I still have all original coolant sensor on my 98
