Hi, I am currently changing my plastic radiator fan for a metal one and between the fan and the radiator is another radiator for cooling the oil.
Is it ok to put the new metal fan just before the radiator and the little oil cooling radiator behind the big radiator? I am a bit of a novice on cars :)

*the metal fan is an extra one, i have one on the block also...

What car????

'67 camaro 454 cui

I did my old 4x4 truck that way and it worked fine, but it had lots of room.

I am assuming the little "oil cooling radiator" you are referring to is the transmission cooler. If so then in most setups that I've seen or worked on, transmission coolers typically will hang on the front of the radiator which is how I believe you are proposing. So the order would be engine, fan, radiator and transmission cooler. I have a 454 in my car and that's how I have it setup. (I don't have a mechanical fan but rather electric fans instead) I went a step further and instead of hanging/attaching my transmission cooler directly on the radiator, I fabricated a small bracket that allows the transmission cooler to be mounted 2 inches in front of the radiator leaving a gap between the radiator and transmission cooler. IMO, this allows for a little more breathing room and better cooling.

Just saw the "*the metal fan is an extra one, i have one on the block also..." Would this be an electric fan that you would be adding while leaving the mechanical fan in place?

zlek 131, yes I mean the transmission cooler. I want the order to be engine, mechanical fan, transmission cooler, radiator, electrical fan. Would this be ok?

I want to put the transmission cooler there so I can but the extra electrical fan as close as possible to the radiator.

thanks,

I guess technically that should work as long as the electric fan on the other side (outside) of the radiator is pushing air into the radiator instead of pulling air through it (as it normally would if mounted on the inside). So you will have the mechanical fan pulling air through the transmission cooler and radiator while the outside electric fan is forcing air through the radiator. Seems a little redundant as a single electric fan on the inside of the radiator pulling air through should get the job done.

Assuming you are wanting to add the second fan because you are overheating...:
What is your mechanical fan setup (flex fan, clutch fan, etc)?
Are you currently running a fan shroud with your mechanical fan?
What kind of radiator are you running?
Are you overheating while driving or idling?

Sorry for the late reply zlek131, i' ve been to a 5-day festival

I don' t have a shroud yet, but I am planning on getting one,
as for fan type and such, i have some photo' s to clear things up:

The engine overheated just once while idling (for 15 minutes) on a very hot day

the extra fan I am installing is a permacool high performance 16 inch 6 blade one, The reason I want the transmission cooler on the other side is that it' s to big to have both. And i' m wiring the extra fan to come on when the engine gets to hot, so on a normal drive it' s of

I want the order to be engine, mechanical fan, transmission cooler, radiator, electrical fan. Would this be ok?

Not the best idea, you are heating up when sitting because you are not getting enough air through the radiator core. Adding an electric "pusher fan" in front of the core is just going to block air from getting through the core more than it already is.

Your problem is mostly not having a shroud, as your current fan spins most of the air flow it generates is going to waste. Air is kinda like water it takes the path giving the least resistance. In your case the core is creating the most resistance. The shroud forces the airflow generated by the fan to come through the core...

Start with a shroud and maybe look into a clutch fan setup, that flex fan is designed to flatten out at higher RPM and blocks air flow, it's great for the drag strip not the street. If you are intent on an electric fan remove the mechanical and mount the (puller style) between the core and the engine leaving the full surface of the core exposed to allow access for air to get into the entire core.

Ok thanks, I' ll look for a shroud.

Im not a fan of hanging anything in front or behind a radiator...
my trans cooler sits on 2 brackets attache to the bottom rail of the radiator, the trans coolers leans back to the chassis rail.
in over 150000 miles it has never been an issue, hitting anything or required special care.

Just getting back to this thread as I've been on vacation. As Dennis already said, get a shroud and you'll bee amazed what difference it makes. It's also a cheap fix and may save you a finger or hand in the future. Let us know how it does once it's on.
