340 runs hot when stuck in traffic

[ammo]

When moving with no traffic even on hot hot days cars temp is fine.  But in my neck of the woods it easy to get stuck in a lot of traffic at a moments notice.  10 minutes idling in traffic it starts heating up.  Have a 4 row radiator and fan clutch with no shroud.  Was thinking about a 16 inch pusher in front of radiator but on looking the car over I see I can fit the a 16 inch puller between fan clutch and radiator.  I know the puller would work better but would look kinda cramped in there.  I considered trying a shroud but since I am not even sure where the radiator came from and even more where the fan clutch came from I might have fitment issues.  Its a small issue really, and don't want to throw a lot of money at it.  Since its only when idling for a long time in traffic, would you go with a shoe horned in puller or a wide open plenty of room pusher?

I was having the same problem and the fan shroud made the issue dissapear, you would be surprised at how much they work. I have heard alot of good thigns about electrnic fans but I have kept my mechanical one in place. I did check and make sure it was still working.

My car could sit in rush hour traffic and not overheat...

You need a fan shroud.

I'd try a shroud first, electric fan will require a complete upgrade of the alternator and wiring harness.

Get a shroud. How wide is your rad? Post some pics and I'm sure we can figure out what you need for a shroud.

I will post some pics of the radiator when i get home with measurements.  Thanks guys.

once you get the measurements post them up here,   I have a shroud from a C body rad, if it will work for you

Lot of electric fans require only 10 to 15 amps. No upgrade necessary.
4 Cores can sometimes be too restrictive to airflow.
Puller fans cool about 20% better than the same pusher fan.

Not going to get much air flow with 15A, everythinhg I've read indicates you better plan on an extra 50-75.

Radiator is 27 by 22.  Fan shroud bracket holes are 26 inches across.  And the lower bracket holes are 12 inches down from top holes.  Having problems getting a good pic loaded.  The bracket can be seen right of the battery cable.

the shroud I have measures 26 and 11-3/4 on the bolt holes,   the fan position my be the question though.  this shroud is from a c body and may or may not fit.  not that far away about all I can say is dry fit it and see if it works for you.

check out amps used on this one:

Depends on efficiency of motor, design, weight of blades, etc. I've seen fans on Summit at 3000 cfm drawing 10 amps.

without a shroud, you are churning air to a large extent.

You can make almost any shroud fit.  Make your own aluminum brakets out of 3/16 x 3/4 x 4 ft stock at Home Depot.
Its plastic, you can cut it, drill into it, etc.

From what I can see of your rad it looks the same as mine and it measures out the same. Aftermarket shrouds are available. Call Roseville.

You can alter it a little like Bob suggested by making a bracket and trimming the bottom a little for the cooler lines.  You seen how mine sets away from the rad a little bit.  You got some great comments from a few of the neighbors, they all say how sharp your car looks. Talk to you again soon.
