Look What I Found
 

I have been chasing a heat spike issue with my 85 Z28. After replacing the 195 thermostat with a 160 the problem diminished, but not gone all way. I then decided to replace the clutch fan and did. However, when I raised the hood I found this!!!!https://cimg8.ibsrv.net/gimg/www.thi...8307530838.jpg

Yes Sir I am very disappointed in my 32 year old upper radiator hose!!!! Lmao

Re: Look What I Found
 

WOW. I have seen the lower hoses do that, never the upper.
That picture is proof.

Re: Look What I Found
 

Wow, that's pretty bad for flow, isn't it.

You should replace the 32 year old radiator cap, if you haven't already.

Re: Look What I Found
 

Yes Sir I am going to be replacing the radiator cap as well.

The Camaro now has a new water pump, lower radiator hose (previous owner),thermostat 165 with 3/16th's vent hole, upper radiator hose, clutch fan, radiator cap, and fresh antifreeze. Now we'll see if she creeps up to 220 in the South Texas heat.
