Talking Re: Woody am I ok with a H/E that has 3/8" flow? Also, MB yellow coolant?
I designed a 3/8" cooler that was great for temperature drop or differential. It had a flow rate below that of the LET using a johnson pump (3.7 GPM) and I had to change it to work better. It measured out as a bit better than stock, so that was changed. Dropping temperature is good but the goal is to cool lots of water to reject largeR quanties of heat.

I accomplished this by placing the two coolers in parallel to reduce the restriction 4 to 1. When done I was at 3.1 GPM which was good as it had like 4 times the area of the LET design and over 5 times that of the factory H/E.

Coolant on the other hand is coolant as long as fluid protects the metallic surfaces and transports heat. Remembering that antifreeze only carries 60% as much heat as straight water. Water is agressive to metal and other things like the Grand Canyon or Luray caverns so we dont use it except for race applications.

I like and trust Prestone since they were making radiators for the P-51 mustang. The color is for identification and branding, there was a red one that was sorta dumb for the color of rust in the car is .......... Iam less than a purest and as long as its Aluminum safe its ok in my book. Others get all twitchy cause its not factory, but if the chemistry is good, then Ill use it. Foo on factory, they are profit oriented where service is concerned.

My OPINIONS worth the paper it isnt written on unless you agree with me, Hee Hee.

Enjoy, WOODY
