Cooling system bypass pipe
 

I noticed that this was missing on my '85 when I did the water pump, and then promptly forgot to look for a replacement till now. My temps are fine how important is this to the efficiency of the cooling system?

I'm ordering this part when I can find the crush washers. My search skills are weak on Peachparts.

up to '84 had it, '85 did not.

Makes me wonder why, but since my temps are fine, I'll just leave it. Thanks for the info.

I concure, the 85`s did not have the bypass pipe. I added one when I replaced the engine.

Not sure why the 85`s didn`t have it, but every one I have come across it is missing. maybe a cost cutting measure?
