Don Coatney Posted September 5, 2010 Report Share Posted September 5, 2010 (edited) Don,Do you find that the pusher fan does indeed cool the engine well enough in high temp situations? There isn't alot of clearance through the front grilles and I was curious about how the venting is working for you to cool the engine. Thanks, FG. I have the fan thermostat set around 170F. On 95F and above days the fan shuts off after a couple of miles if I am running at any speed above 35 MPH. If I am setting at a stop light for an extended period of time the engine temperature (on a 95F plus day) will creep up to over 200F but less than 212F. The only time I had a boil over was when my engine timing advanced due to worn ignition points. I have been running this setup for over 5 years and close to 40,000 miles. The fan controller has provisions (an extra contact on the relay) to turn the fan on every time the air conditioner is turned on. As I do not have air conditioning I used this extra contact for a manual toggle switch to turn the fan on manually. I rarely use this switch but it is nice to have. Switch is lower left under the radio delete plate in the picture. Edited September 5, 2010 by Don Coatney Quote Link to comment Share on other sites More sharing options...
martybose Posted September 5, 2010 Report Share Posted September 5, 2010 Marty, what year Dodge are we talking about? I would be very interested in this conversion. Could you post a picture? Thanks George Not sure what year they are, as I found them on eBay, but I'll bet the D24 guys know. Here's what they look like: Marty Quote Link to comment Share on other sites More sharing options...
knighthawk Posted September 6, 2010 Report Share Posted September 6, 2010 we used to do a lot of parades with the wifes '69 Cutlass convertable, sometimes it got hot. If I run the RPM's up a little, whiles sitting in the parade, it helped by pulling a little more air through the rad. Finally went to the junk yard and found a small ( 8 or 10 inch) fan, and mounted it in front of the rad, just behind the grill with a switch beside the steering column,,,,,,,,,,,,,no more problems !

DonaldSmith Posted September 6, 2010 Author Report Share Posted September 6, 2010 I got a 16" pusher from Mr. Cranbrook. (He's the guy that came to see me at the Dream Cruise a few years ago. The "Met a Friend at fhe Dream Cruise" thread has photos of my big brown DeSoto chumming with his blue Plymouth.) I bought the fan for supplemental cooling during parades. The fan mounted easily in front of the radiator becasue the DeSoto already has the horns with the 90-degree bends. The fan housing has bosses that receive bolt heads. Bolts at the top slip behind a cross strut into some clips I fabricated. Bolts at the bottom engage corner angles that I cobbled to be screwed into the dust shield. The fan is 12-volt, so I power it from a jumper pack. I made up a wiring harness with a separate switch stub, all Rube Goldberg for now, but it works. As a matter of fact, I was in a parade today. The weather was cool, but we alternately crept forward and stood waiting, while two lines of parade entrants merged. A lot of idling with the car in gear and the fluid coupling doing its thing. Even when we were moving, I had to ride the brake. I did notice the needle creeping up a few times, and turned on the fan for a few minutes each time. The test will be a hot summer parade. But tuning up the car may have also helped it run cooler. Quote Link to comment Share on other sites More sharing options...
Harvey Tank Posted September 7, 2010 Report Share Posted September 7, 2010 This summer in my neck of the woods it was a cool 90 Deg. and my newly over hauled 218 in my P20 with a 160 Thermostat it ran @ around 180 in a Parade Quote Link to comment Share on other sites More sharing options...
