Hi Guys another update 90 degrees here on Saturday went for a fairly long ride never went over 180 degrees. I guess the next step is to get a shroud and a clutch fan. I can say I can feel the hot air coming in the floor vents I didn't feel that with the electric fans. I definitely feel the horsepower difference with my butt meter not huge but I do notice it.

I have an update ordered the spring for the lower hose. I took the Focus fans out and installed my old stainless steel flex fan no shroud. Drove around last night never came off 160 degrees. I could feel the hot air coming out of the floor vents definitely moves a lot more air.. Cyclone03 was right. Ive been looking for shroud that holds two fans that will fit this radiator not much made. Maybe ill go back to a clutch fan. Its supposed to be in the mid 90s this weekend stay tuned.

I thought about removing the shroud as a test. I am only 2 blocks from a long road where I test my car lol 3 miles with no intersections, yes even in NY lol. I have no idea what the pulley ratio is but been running this combo since I was 16 that's more than 45 yrs. Only in the last 5 or so have I notice the high temps. I just usually avoid hot days or bite my tongue.

All good points. I think I will add a spring in the lower hose. I'm not going back to a mechanical fan again so maybe better fans. Worse comes to worse a bigger radiator. I would just like to get it right. I never believed the to cold of a thermostat thing 180 160 same thing in my book.

Hi Ross
  1, No
  2. no it ran warm always over the thermostat by 20 degrees.
  3.yes it will come back to 180 when it idles at a light on a hot day say 90 or hotter 190
  4. Yes
  5. On the highway 210 215 forever unless its below 80 degrees. 50 degrees or less 180 or less. I dont do much highway driving its just a toy to and from cars and coffee or a quick race.


I even bought this to force the air thru the radiator.

Good ideas guys most seem to like the 28" cross flow radiator, which means fabricating hoses which is no big deal. Better fans, battery in the trunk. No vacuum advance on this motor timing is locked, no Centrificall or vacuum advance. the good Spal fans are like 180 each. Something to think about.

I have tried 2 or 3 different thermostats even a high flow Moroso.
