[DeTomaso] FW: MDs Radiators (1985 to 2008)

[Jason Eaton]

I have the same setup as Trusty/Taphorn and it works well around town
and at the race track. However I still over heated when running 5500
rpm for 90 miles at the last ORR. Therefore I need more cooling and am
looking at a new radiator to replace my fluidyne.

I added a bleed nipple on the top of the "thermostate housing pipe"
that used to run to the "swirl" tank. It now bypasses the swirl tank
entirely and goes down underneath the car.

You can read about the modifications here;
