[DeTomaso] cooling fans

[cengles at cox.net]

Dear Mr. Bronco,

It should be noted that Oklahoma had the HIGHEST daily temperature for July of anywhere in the USA. Due to mechanical maladies in the Engles' Family Automotive Fleet, my wife appropriated my car and I was forced to drive the Pantera in the furnace like heat for two weeks.
I drove both Panteras. Both have the same fifteen year old brass radiators. Both have Meriah fans. One has 385 hp and the other one has 485 hp. In the hellacious afternoon heat on the trip home with ambient air temperatures commonly showing 110 degrees, both Panteras showed that they were running hotter than the usual rock solid 190. They ran perhaps ten degrees hotter in suburban city traffic.. They did not overheat. Interstate driving showed normal 190 degrees.
No hood vents. No sucker fans. To paraphrase Mike L. Drew, it can be done rather simply.

It is a bit warm here, Chuck Engles
