Im having issues with my car running hotter than it should. Sitting at idle my temp creeps up to about 220 with the hood open and if I close it get up to 235. If I rev the car up it actually cools down a bit. Im just wondering who has had overheating issues switching to turbo. Here the specs on my car to give you an idea.

408 LQ4 @ 9.0:1
Twin 70mm Turbonetics w/ wrapped turbo, up and down pipes
160 degree thermostat
Griffin 24x15.5x3 core radiator
Zirgo 3200 (I dont know if I believe this) CFM Puller fan with shroud.
Fan is on switch at the moment
Brand new stock water pump
Kurt Urban steam vent kit
No A/C

The block, heads and head gaskets are not an issue as these things have all been checked. The car cools down while driving so I am lead to believe its a fan issue. The only thing that confuses me is that, I have a shrouded puller fan and my tuner has said he has seen cars with no shrouds or just pusher fans not get this hot. He said those cars rarely got over 200. Im at dead end bc I cant figure this out.

 

i dont have a cooling issues but i would agree with you that it is a fan issue. i run 2 derale fans but they are pushers. car never gets hotter than 185 with 160 stat.

 

I guess im just going to have to try another set up. Im thinking of trying the ford contour fan set up and see if that works.

 

Do you have a coolant expansion tank or just an overflow?

 

just the stock over flow tank

 

I added an expansion tank or pressurised settling tank to my system and it really helped. I can sit and idle forever now and it will not go over 210 where as before it would keep climbing and climbing and would go over 240 before I shut it down. Definitely helped me.

 

Sarg where did you mount the expansion tank? Do you have any pictures?

 

You have a fan issue. Put two Spal or Derale pushers on it.

 

I put mine on the firewall, but I have a foxbody. Not sure pics would help but I can get some if you want. I ran a t in the bottom with the heater hose output going through the t and my steam port going to the tanks as well then one line going out from under the cap to the overflow

 

Definitely sounds like a fan issue, I had the same problem actually. Finally switched from two 10in ebay pushers to a single 16in puller. BOOM, temps were fine. I still have a problem with getting too hot on long pulls so ill be upgrading to a SPAL 16in fan and a smaller pusher. Also twin turbo, turbo blankets, 160 stat, and wrapped down pipes.

 

Sarg i didnt know you had a fox, I dont need pics then. Thanks for the info on the routing for the lines though!

s25hanh what 16" fan do you have now. I have a Zirgo and some people swear by them but I already had one melt on me. Its rated at 3200 cfm but people claim thats a false number. Has anyone else dealt with zirgo?

 

OP I'm having the same problem as you. I have the same rad with two 10in Zirgo fans. IMO these fans are junk. Definitely Chinese ****. I'll be switching to two 12in Derale pushers here soon...

 

I really hope the zirgo fans are crap and if I buy two top of the line pushers it will fix this problem

 

That is what I am gonna do. I will report back with my findings. Lol

 

Go with intrepid fans or a single taurus fan.
I let my car idle for 4 hours in my driveway yesterday, never got above 194*

 

What type of set up are you running ron?

 

4 hours???

 

Timing and fuel make a difference as well. I only ran one fan no shroud and never had a problem.

 

All my cooling issues when away when I MADE the stock puller fans fit.

 

ddnspider do you have any pics? I was thinking of dropping my lower radiator support a couple inches and trying to fit in my stock fan and radiator.
