larger flex fan

Yet another overheating thread

Time for a new rad core and when I am at it I am determined to cure the overheating problem once and for all.
Engine is new as is the water pump

I already have a Texas Cooler fan (or at least a yellow plastic fan that I think is a TC) but it seems to me that it is all about airflow at idle. I also have a Tiger and my airflow thoughts are proved out in the article on Tiger cooling tests and I suspect that similar airflow issues exist with the Healey.

Is a stainless flex fan more efficient than the TC?
Same question with a larger OD flex fan

Is there any reason why one cannot use a larger OD stainless flex fan? It looks tight at the Kilmartin/Nock fan shroud but it could be made to fit. Yes I know it is noisy but efficiency is more important to me. Surely someone here has tried this

Is there an electric fan with a low enough profile to fit between the rad core and the X braces?
IF the core can be offset in the stock tanks now is the time to deal with pusher fan clearance

Maradyne makes a low profile 14" fan that will fit the stock radiator installed as a pusher (you would want to leave the core in the stock position to maximize clearance up front) The fan is available here: www.thewedgeshopstore.com
I had to bend the crossbrace forward a bit for it to fit:

Here's what it looks like mounted to the front of the radiator:

Having said that, I wasn't satisfied with how it cooled my V8 and ultimately went to an aluminum radiator, which I'm still evaluating.

By the way, If you're car is overheating it may contribute to the engine run-on that you mentioned in the other thread.
