    cooling problem is back at 75 outside

    I am sorry to bring this up but I dont seam to have anyone else to bonce things off. My 65 stock 289 auto with a 2 core 1" tube Champion radiator will not stay cool at idle with the AC on and its not really hot out. I have a 17" Derali HO  fan (says it moves 2400 cfms) with a autocoolguy controller. I only have 3-1/2" of clearance.  Where I think my problem is with 324 sq in of radiator and 225 sq in of fan. No shroud. That is like 2/3rds of the radiator Inlet and outlet on same side. Should I make a shroud?

    Re: cooling problem is back at 75 outside

    Looks like it's a 2 speed fan, pusher or puller.
    Is it getting high speed, and working as a puller?

    My shroud is only about 3/4" deep.  Works just fine.  I made it from some 1/8" thick aluminum plate and 3/4" x 3/4" angle.  Riveted together and painted black.

    Re: cooling problem is back at 75 outside

    Is fan running while a/c is on?
    Are you using transmission cooler in radiator as well?

    Re: cooling problem is back at 75 outside

    Below is my setup.  Provides adequate cooling even when using the Vintage A/C system in traffic or on the open road.


    • Aluminum Radiator: Summit SUM-380461
      • [list=circle]
    • Installs in the stock location.
    • Core dimensions: W15.625”x H 17.375”x D 2.25”

  • Flow Kool Water Pump (#1680)
  • Electric Fan: Spal 16” single-speed #30102120
  • No Fan shroud.
  • DCC Fan Controller #FK45
  • 180° Thermostat

    • Note that I had to slightly trim the nose of the water pump to avoid contact with the electric fan.
     

    65 Fastback, 351W, 5-speed, 4 wheel discs, 9" rear,  R&C Front End.

    Re: cooling problem is back at 75 outside

    Aluminum radiator-Summit stock 289 two row 1” tubes (Northern Radiator stamp), like BobE radiator...don’t remember part number.

    Electric fan-Summit (sum-g4903) 14” rated at 1585 cfm...no additional shroud, on with ignition only via a relay.

    Used with 289 (.030), stock type water pump, 180 thermostat, transmission cooler used with c4 with additional external cooler inline, stock water pump pulley.

    Currently with 5.0L/T5, stock ‘92 type water pump, 190 thermostat, transmission cooler not in use, stock water pump pulley.

    I currently do not have a/c installed.
    Haven’t had problems.

    Hope this can help.

    Re: cooling problem is back at 75 outside

    My solution to this is a steel ridged six blade big a.. fan, no shroud. I've never had an overheating problem even when I was still running the stock rad with the c4. Mildly modified 289. Aluminum 3row rad.

    Are there electric fans without shrouds?

    Re: cooling problem is back at 75 outside

    Here is what I built today. And friday saturday we are going to get hot 88-90 OH NO HOT lol. Anyway 3/4 x1/2 aluminum angle and a piece if 1/8 plate A jig saw and a skill saw . I think it turned out good because I can install or remove without pulling hoses. Its close at the pump and a bitt closer at the AC, but the motor doest move forward so It should be fine.

    Very well done.  I have a huge appreciation for those who take the time and do things right.

    What about your radiator cap?? What pressure? More pressure will make it boil LATER.  Shelby apron 'cured' mine. Maybe a remote A/T cooler?!

    Re: cooling problem is back at 75 outside

    13lb cap. The other day with about the same temp maybe a deg or 2 cooler it was idling at 210, today with new shroud 192. And it didn't even get hot until I pulled off the freeway to turn around.  I am running 50/50 mix.  I will update everyone after it melts tomorrow in the heat lol
    You all are a big help, I really do thank you all for the input.

    Re: cooling problem is back at 75 outside

    I replaced my original radiator many years ago, I started with a 13# and had similar issues without a/c.
    When I changed to 16# with new brass radiator, that issue disappeared.
    Still using 16# with my aluminum radiator for 289 and 5.0

    A/c will increase the inlet temp to radiator, especially noticeable at idle.
    With clutch fans at idle it is noticeable as well as “grapevine” inclines even at interstate speeds in hot temperatures.

    Nice looking fan shroud too.

    Re: cooling problem is back at 75 outside

    IF Oregon is like Gig Harbor, Wash. weather........you may be waiting awhile for a "heat wave"!

    Although...when I visited there last summer they were 'suffering' from a heat wave. I think it got up to 90* during their 4-day heat wave! After that it drop back to the normal of 68-72* summertime weather.  Then Labor Day rolled around and the rain started until  Mother's Day.

    According to   "a-trusted-source... they don't tan there....they rust!"
    It's a GREAT place to visit though.........
