I'm a new member and I have some questions that I'm hoping you guys will be able to help me out on this. First off I have a 357 sbc motor in my car. I have a all aluminum double pass radiator with twin electric fans on it (3000 CFM). I have a fan switch that turns on at 180 and off at 160. So
my problem is I just put my custom procharger kit on and a huge front mount on and now I cant keep the motor cool. I gets up to about 240 so I shut it off till it cools down. I had a 160 thermostat in and I took it out and put a reducer in and that doesnt help either. I have a mech water pump. So the only thing that I can think that could be the problem is that the pulley procharger sent me for the water pump is too big and not turning it fast enough or the intercooler is blocking too much air.

I already called procharger and they said that is the only pulley they have. And yes the air dam is on the car.

Does any one else have a front mount on there car and have this problem?

 

sounds like the intercooler is blocking all of your airflow. is this a racecar or a street beast?

 

Its a street and drag car. I have a picture but i dont know how to upload it?

 

there is a little paperclip on the toolbar when creting a post, click that and a popup will come up, it has to be a GIF or a JPG click browse, find the picture, click upload, than you're done.

 

Thanks for the help I found it. Here is a picture of my front mount.

 

I would try to Fab up some kind of ducting to bring fresh air to your radiator, it looks to me like the fron mount is blocking all of the airflow.

 

this is a stupid question but im just checking. are your fans pulling air or pushing?

 

Make sure your lower rad hose has a spring in it to prevent collapsing. This will cause it to idle OK but heat up on the road.

 

I have stainless hoses on both the top and bottom line so they cant collapse then. The fans are pulling like they should be too.
I ordered a stage 2 stewart pump and a 180 thermostat, I also fab up a stainless air dam so I will put it all on this week and hopefully that will fix the problem.
Thanks for all the help so far..

 

What's the current status?
Is that a larger aftermarket radiator?

 

Well I put the water pump and thermostat in on monday night and last night I put on my new air dam that I made so im hoping to take it for a drive tonight or tommorrow and see if that fixed the problem, I hope so. I would of been fixed last week but I broke my foot so that puts a damper on getting stuff fixed.

 

Well I got my car out and took it out for a drive tonight and I went like two miles up the road easy on it and it ran about 209 the second time i drove a little more and got on it really hard and drove around a little more it got up to 220 this time. I guess I should of drove more and see if the temp would come back down or climb more. Maybe ill take it out on the highway this weekend and see what happens.

 

Can you post a pic (or possibly provide a part #) for what you used for rad hoses? I have a double pass radiator too, and I cut a rad. hose to fit I found on the shelf at Napa for my upper hose, but I am stuck using the stock lower hose for now, which doesn't fit very well, but I haven't found any other hoses that clear the idler arm.

 

dumb ? but like it was said above, are your fans pulling or pushing? have you put a pressure tester on your rad to test the pressure of your cooling system?

 

Sorry its been so long since I have wrote on my post but Ive been busy with my new house and getting married and everything. So everything is fine now, on a 90 degree day it gets up to like 190. I added a stewart stage 2 water pump and put water wetter in the radiator. About the radiator hoses I bought a stainless kit for the upper and lower so I cut the hoses to fit. Ill get some pics this weekend when I bring the car to my new house.

 

Glad you got it fixed. Updates for pics? I'm also in need of a radiator hose to fit the new bigger radiator and clear the idler arm.
