So I was seeing a little leak and found this...




looks like that might need replacing .

 

 

I would suggest to do something like this and its a permanent fix. Hope it helps.



Drill hole slightly smaller than the threaded end of the barb.

JB weld the fix.

Force the tread into the plastic reservoir.

Drill a hole on the threaded part to reach the lowest level of the coolant.

 

What type of plastic is it? Does JB Weld bond correctly? I just noticed mine starting to weep last week, going to need to either buy a new tank or do some type of repair like this.

 

If I do this repair, I will be using this product. This is what I used on my plastic sunroof drains.

 

 

Or, if you're okay running without the throttle body heater you can carefully cut off the nipple and plug the hole with a short sheet metal or all-purpose screw, wrapped with Teflon tape. The only thing that line does is return coolant from the throttle body heater.

 

nice work Gerry. I was thinking of something along those lines.

 

 

Agreed. Why try to repair a part that's so cheap and critical to the cooling system? Having owned many BMWs and Audis, the coolant reservoir is a part that you usually replace every 60k miles preventitively. They all get brittle from age and heat.
