Option B for Dual Pass IC

Comes as a complete kit with everything needed to install on your car except the mounting bracket. This kit will make it easier to bleed the air from your intercooler system. The point is that the small line will always have coolant flowing out of it and feeding the Option B's overflow bottle, and when air comes out of the line it stays in the top of the bottle and air-free coolant drains out from the bottom of the bottle back to the IC pump and heat exchanger(s).


Cobalt bracket and Ion Redline bracket can be found here.

Surge Tank Anchor Tab Location

My Surge Tank is from a 2006 SS Cobalt and the tank anchor tab is in a different location than the tank you sent. Do you make a 2006 tank so that I will nit have to fabricate something to fit this tab? Then the kit will be a slam dunk. Go to http://www.britishv8.org/Triumph/AlbertGary.htm
