[DeTomaso] Radiators

[Stephen]

Whilst I am enjoying driving 5332, I noticed that I have a seep from where one of the radiator tubes enters the header tank.  Looks like it has been there a while, small seep, but left a puddle when I ran the engine at 1500 rpm for 10 minutes to charge the a/c.  It's a Fluidyne radiator, bought and installed in 2011, with perhaps 4,000 miles on it.  

Hence the following questions:

Is it worth getting the leak tig'd?  I have no doubt that a friend can weld up the current leak - it looks to be on the front of the tube and pretty accessible.  But, search "Fluidyne radiator leak" and one gets a lot of hits.  What is the experience of you guys who have them in your cars?

I see that FlowKooler has a more conventional radiator (not aluminum).  Do any of you have experience with their unit?  I note they state:  " Repeated calls from Pantera car owners complaining about leaking aluminum radiators in their Panteras led FlowKooler to work with its sister company, The Brassworks, to design not only the primary radiator and fan assembly but the auxiliary cooling system for the rear of the car."  While their radiator costs more, well, perhaps not depending on how lont Fluidyne's last.  

Any and all comments welcome.
