54 V 8 overheating

Oct 01, 2006 31 Replies

On a "brand X" w/AC, I removed the standard fan and put an electric fan in front of the condensor. If the car go hot, a spritz from my water system (W/S sprayer) would result in an almost-instant drop of coolant temp. Two 8 or 9" fans should you for your car.Water needs refilling seldom. This was in San Jose

A shroud on the Lark works unbeleiveably well. It doesn't look like it should work but there is alot more airflow behind the fan then without it If the shroud were used on all the OHV6's maybe there would have been fewer head problems. If you look at most newer vehicles they also have flexible curtains on the sides of the radiator extending forward to trap the air entering instead of letting it go around the radiator. I think something like these on a Lark might make some difference. For my AC installation, I also have a 6 blade fan too; noisy yes, but it moves alot of air.

Steve,

Those flaps are still in place on my Hawk and I too am using a smaller pulley on the water pump and fan. I am building a '54 coupe and I'll remember to remove the A-arm flaps as you suggest.

Ok Guys here is what I did. I followed some of the advice given and here are the results. Tell me if this sounds normal.

70/30 mix of tap water and coolant and 1 jar of water wetter. I let the car heat up in the driveway with the radiator cap on and hood closed. when the temp guage got to the half way I used a lazer temp thingy and the results are. At the point where the sender unit is 185 degrees. at the throat of the radiator 200 degrees. Does this comport. Also tell me some more about the flap above the radiator. This car just has a metal shroud that covers the fan area.

Thank for your help. Mark

Ok; Tell me some more about the flex deflector on the radiator. What does it look like and does it have a part #? Would I see it in the chassis parts catalog?
