No. Outside air still gets pulled through the condenser first.

no it does not. radiator fans blow, not suck. In said situation, it blows through the radiator first, then condenser


I've read some strange things on BITOG but this one is at the top of the list!

If they're mounted in front of the radiator/condenser like I described in the HP TV episode, they blow. If they're mounted behind the radiator, they suck.

If they were mounted in front and were sucking air, that wouldn't work to well in low speed driving conditions.

I'd be surprised if the AC cooled more than -5F from ambient. Might as well just leave it out!

I'd think forward-blowing fans would have a REALLY hard time keeping up when going down the highway!

I'd say it depends on how far down. By the time you get to the bottom of the radiator, how close to ambient temperature is the coolant?

If it were at the top, where the coolant enters and is warmest, I'd be really concerned.

However, if the condenser is at the bottom, the coolant is cooler and the air passing over it will be closer to ambient temp.

It probably won't work as well at idle as folks have suggested. But I don't think it will be as bad as folks are imagining.

weird. I had a '57. There was over a foot of room between the radiator and the grill. An adolescent could sit there on the radiator pan between the two.

A/c is good for 20°F below outside ambient. Beyond that it will begin to struggle. They would be better off mounting it in the trunk with an electric blower to pipe in outside air and vent the exhaust.

An engine under reasonable hwy cruise could easily breathe 120F after the radiator into the condenser. So the A/C would comfortably bring the cabin down to 100 and would work hard to get it to 80....

Thermostat won't really matter. If the engine is at 1/2 throttle, it will generate 1/2 throttle's worth of heat, which will be vented to the outside. radiator temps are variable-- as the t-stat only opens to the extent needed to maintain temp. If the t-stat is wide open, you're at the limit of the cooling system.

My radiator fan sucks through , NOT blows through.
And I've never seen a belt driven fan in front of a radiator.

Its like [censored] in your septic tank, and having it flow in to your toilet...

I had a Toyota once that had the condenser mounted parallel to the ground with a fan on top and louvres on the bottom. worked pretty well. Totally away from the radiator and other coolers.
