I've got a 72 swinger, 225 /6. Making it a daily driver. Is an electric radiator fan a good idea? And any recommendations are appreciated. Thanks!
I'm putting it back together. I don't have a fan shroud and was curious if there are other better options.are you having an actual problem or just curious? no reason the stock setup, in good shape, shouldn't cool a stock motor
22" or 19" radiator? do a want ad or hit some wrecking yards. /6 fan shrouds shouldn't be too hard to find. that car can make a great daily driver, just need to work out the kinksI'm putting it back together. I don't have a fan shroud and was curious if there are other better options.
The Contour dual fans move a lot of air, and fit nicely on a 26" radiator. Keeps my 451 cool in mid-90's humid Missouri summersTo match the airflow of an engine-driven fan, you need a powerful electric fan. The 2-speed Taurus fan move a lot of air and is popular with hot-rodders.
The electric fan turns on from refrigerant temperature, so its main purpose is to cool the evaporator when idling. Even that isn't sufficient, since the AC gets noticeably warmer when sitting at a long stoplight. That is also true for my 2002 Chrysler minivan, and yes I verified that both fans turn on. Once you start moving 30 mph, the AC gets noticeably cooler.
My slanty has no shroud either, and just a 4-blade fan. It's been that way since I got it in 1994.I don't have a fan shroud and was curious if there are other better options.
Correct, I meant the "condenser". Like most older cars, our 1985 M-B has a 1-tube copper condenser. The parallel-flow aluminum condensers in modern cars give 30% better cooling, so some owners retrofit one. Some also change from the Harrison R4 compressor (used in many Chevy's) to a modern Sanden 7-piston. I did until the aftermarket bracket cracked, but didn't notice the Sanden worked any better. Our 2002 T&C has a parallel tube but still the AC doesn't work well when idling at a long stoplight. A disadvantage of parallel condensers is that you can't flush out debris like older ones, though most people today just install a new condenser. Many owners think M-B under-designed the AC for the U.S., especially CA Central Valley where I live (110 F days plus evil sun), but the heater is built for frigid German winters, having a monster 3-tube Behr heater core as found in semi-trucks and climate system which disables the cabin fan until the coolant is hot so no risk blowing cold air on rich owners (Germans fear 'une draft' will sicken them).I believe you meant, "cool the condenser"
Sounds like you don't have enough condenser if both fans are working and the A/C warms up. Or did you do a conversion to R-134a on your MB diesel?
