Hi, looking for some help! I bought this car used and one of the nipples on the radiator was capped, but it recently cracked and leaked. Can anyone tell me where this is supposed to connect to?

 

Hi, I have a 2008 Express and replaced the radiator a few years ago, the aftermarket radiator had the nipples also. The parts house said it was the correct part, and that it is used for other applications, that utilize the nipples. Looks like your overflow reservoir is empty.

 

Thanks! Yeah I was looking online at replacement radiator and none of them had that nipple. So I’ll just plug it again. For some reason the overflow tank is always empty. Not sure what’s going on.

 

Yep same thing here. I used 5/16 fuel line, clamps and plug. One thing I learned on mine was to also be careful on hose and cable routing. 3 years to the day my replacement radiator started to leak where the negative battery cable rested lightly against the plastic tank. Just lovely.
