I have a puller fan on my car. 72 cutlass with a 455 in it. I recently added vintage air. At idle the temp rises quickly, when in motion it cools great. I'm wondering should I get a pusher fan. To me it seems like the regular fan and the puller fan are working against each other while idiling making the temp rise. Any help I can get with this will be appreciated..

 

You have a stock engine mounted fan and a puller fan in front or behind the radiator? If in front and puling air forward then yes, they are working against each other. What type of fan is attached to the engine? Is there a shroud? What temps are you reaching at idle and at speed.

 

Yes I have a stock fan. Actually the electric fan is mounted on the condenser. Yes I have a shroud. It has got up.to 230 and my hot light came on.

 

I would remove the puller fan, it works against the engine mounted fan and blocks the incoming airflow.

 

Ok thanks. I will go and buy a pusher fan. Thanks again..

 

I think you can reverse the wires on some electric fans and it will reverse the direction. That would be a lot easier and cheaper than replacing it.

 

So which side of the condenser is this fan attached to? Front or back?

If it's on the back, it is trying to move air in the opposite direction that the factory fan is trying to move air.

If it's on the front, it is blocking the air flow from the factory mechanical fan, and removing it and installing a pusher fan won't change anything - the pusher fan will still block the air flow from the factory mechanical fan.

 

It’s on the front of the condenser close to the grill. I changed the wires and now it’s pushing. So basically you’re saying either way it’s blocking airflow?

 

If it did not help or made it worse then yes its blocking air flow.

 

Thanks

 

How much distance is there between the condenser coil and the radiator? Do you have a factory 6 or 7 bladed fan with a properly operating fan clutch and a fan shroud?

If the condenser is within an inch of the radiator and the other items are there, your cooling system should be able to keep up without an electric fan.

Have you tried to run your A/C with the electric fan removed?

 

I think the dead horse has come back to life!

It has been said many time over, by those who know what they are talking about, that a stock fan and shroud will be ample to deal with keeping an engine in good shape with the correct radiator properly cooled.
Why did you fit the extra fan in the first place?.
