[Fot] Collective wisdom

[Chuck Gee]

Hello all,

In an effort to constantly improve the car, I’ve been looking at the cooling system on my TR4.  It currently has a header tank mounted to the firewall that functions as the high spot in the system.  This tank feeds the top of the radiator but doesn’t really circulate during operation.  I’ve been thinking of plumbing the feed off of the back of the head into the top of the tank so that it circulates.  

Normally this rear head feed is plumbed to the back of the water pump.  In an exercise of overthinking, I’m not sure if there will be sufficient circulation since the tank is plumbed to the radiator.  Does it matter?  What is the collective wisdom?

Here are some pictures to help illustrate.

Thanks,

Chuck
