Task Force Radiator

[_Ogre]

i used a us radiator "desert cooler'' 4 core copper model w/trans cooler on truk
bought from brothers, drop shipped from us radiator

at the time copper was cheaper than aluminum and i liked the black look

later i bought a shroud and electric fan from brothers it was also drop shipped from us radiator



i ended up covering the radiator so black or aluminum wouldn't have mattered



both radiator and fan/shroud have served me well in 30,000 miles and many 100*+ days

hey ogre, that's a cool trim panel you have there. is it fiberglass? looks good.

thanks
fiberglass
hides the ac dryer, overflow tank and horns well
build details in my build thread

Does looks good ogre

I went all in with a Griffin radiator on my '55, and it looks GREAT but I am sure there are other radiators that will preform as well for half the cost. I think the Griffins are in the $500-600 range... and I think they specifically state they are not for LT or LS applications, but I think that may be because of hose location, and not cooling capabilities...

My top radiator hose inlet is offset to the drivers side, but I dont remeber what part number I ordered, it was like 6 or 7 years ago...

the standard one on their website is listed below:

PART NUMBER: 6-70075

I dont have a ton of radiator shots, but here is some I found that I took during my harness install:

I made a custom shroud/bracket for a electric fan out of galv sheetmetal.

Blue C1 Pin 42

Empty - Fan 1 Control - This will be empty on 99-2002 harnesses. A pin can be added for electric fan control. Programming will enable the fan control. PCM supplies a GROUND to turn on a relay. If you have two fans, keep reading, pin for fan 2 will be on the RED connector C2. You must wire your fans through a relay.


Green C2 Pin 33

Dk Green - Fan 2 Control - some 99-02 harnesses will have a pin here, this was used for the HVAC Recirculation Door control. The PCM would control the A/C recirculation to help cool the a/c system if it got too hot. In an engine swap, programming can be changed to let this control a second cooling fan. Again, PCM supplies a GROUND to run on a relay. You must wire your fans through a relay.

Will the PCM be Required to Controlthe Electric Fan(s)?

Many owners operate electric fan(s) independently of the PCM by triggering a relay through either the A/C compressor clutch circuit or through a trinary pressure switch.

One drawback to these methods when using Gen III PCMs is that unwanted DTCs set as the PCM detects the fan(s) have turned on during conditions that the PCM has determined the fan(s) should be off. One solution is to simply disable these DTCs, which also disables the intended function of the DTC processing. A better solution is to use the PCM’s A/C control functions to gain improved A/C system control and A/C system diagnostics. (See Chapter 11 for more about A/C control.)
