^thats a good idea.....ill have them suckers on all the time! lol

 

I know the heat wrapping is an easy option and short term, yes it would help with cooling. But just like everything else...there is ALWAYS fine print that you should read before doing anything.
One of the only main issues that can happen by using heat wrap is that it will cause the parts that its on to wear prematurely. It changes the manner in which the metal expands when heated and contract as it cools. The wrap causes the metal to fatigue faster. You'll see the stuff on virtually every professional race car because yes the stuff works... but they have the budget to replace those parts much more often. I dont know your budget, but if you have the means and dont care about replacing parts sooner then I'd say rock it.... but if you dont (which is most people) then I'd look for a different solution for your issue.
Just my 2 cents... hope that helps.

 

wires fans to switch

 

hmm i thought you have already upgraded your cooling setup.. on the highway 95-100 weather im at 182-186F around 65-80mph..

upgrade the following
1. radiator
2. fans
3. thermostat

 

I have a stock radiator - no shroud - 1 12" and 2 8" permacool fans on the front - no a/c condenser - 170* thermostat, and I stay below 200* at all times - permacool fans are the shiz too - it actually will get damn cool like down in the 175-180 range even after beating on it with those fans on However when driving im sure the no a/c condenser helps me out alot.

 

^^ haha hella hot inside than your coolant though lol

 

I haven't read the prior responses but here are some things I have noticed on many other types of cars with aftermarket radiators.

They suck.

The factory radiators are normally better suited believe it or not when it comes to cooling. Like many cheap intercoolers these radiators don't have enough cooling tube and fin surface area to allow proper heat transfer. Aftermarket radiators in most cases are just lighter. If you get an oil cooler you will probably see a steady reduction in coolant temps by about 20*F.

Anything you can do to construct a shroud to force air to go through your radiator and not around it would help massively.

These are things I have done to help reduce coolant temps on many vehicles.

It doesn't help that you are running A/C, a necessity in hot humid weather I understand but it doesn't help the situation either way.

Maybe a stock radiator with some large slim fans strapped the to the back of it with some soft rubber vacuum hose slit down the middle and pushed onto the edges of the slim fan frame to create a soft seal against the radiator making it it's own shroud. Then fab up a shroud the same way to funnel air in the front.

Good luck

 

Monitoring via my S/G2 before my vented hood I ran around 196-200 at 60+mph @ 80deg
After the vented hood it stays between 168-174 at 60+mph. @ 80deg
I also have an air diversion panel in place too.

As soon as I'm parking the heat will climb up to 204-210 but I am in the habit of sitting with my car on to let all the temps even out.... until I get a silly turbo timer....er until i'm not being silly and get a turbo timer.

The only other things I have done after that to keep the water temp down was 1-12oz bottle of water wetter... though I have not seen their claimed temperature drops. Next radiator flush I am going to try something called engine ice.

 

those are already done.

 

yeah, maybe i'll have to put the stock radiator back on, get some high quality slim fans.

or change the turbo set-up and get a different manifold, downpipe intake pipe and charge pipe so i can put the stock radiator and fan shroud back in. i made an appointment to go to p-tuning next thursday to check it out.

 

so the koyo radiator that he is running is worst then stock.

 

lol, the koyo radiator that dezod also sells! lol.

 

1. one of the fans might not be working or not making contact (happened to me once, got hot during traffic only)
2. fans wired backwards
3. air in the cooling system
4. bad radiator cap? not sure about this one

I have a Koyo rad and cap with two fans, a puller and a pusher. The puller is on the passenger side and pusher on the driver obviously. Also running a Murray's plus 170 degree thermostat with a 30% Toyota coolant and 70% water.

My highway temp is always stuck at 177 deg during the summer regardless of temp, during the winter it goes down to 175. If I come to a short stop it might touch 180 if it is a longer stop it stays in the low 180's. During heavy traffic it might reach 200, but only for a split of a sec before it goes down to low 190's. The highest I've ever seen was 204, while stuck in an accident with slow stop and go. Drive-thru's are another one that might get it high, but only to 190's.

Funny thing is that when I use the AC the car runs cooler by about 10 degrees, cuz the fans kick in pretty often. Other than that the car temps are very stable and cool. What I like about the Koyo setup over the stock radiator is that the temps are very constant. There's is no roller coaster with the temps, like I used to have with the stock radiator. I got to see a couple of 224-230 with heavy traffic and constant 214 with regular traffic. Just saying.

 

yeah, on my way into work tomorrow, i'll check my radiator fans before i head in, see what they are doing, see if one pushes/pulls or does nothing.

 

I too think the thicker radiator helps a lot.. i got a watercooled turbo that all the stock rad will do is overheat.. i think its the fans and maybe the direction of blade or air flow maybe..


My setup FYI
1. Mishimoto radiator
2. 2 Permacool 12 inch fans in front = Permacool awesome cfm and less amp than mish, 1 permacool 8" fan as puller on the radiator
3. Gates 170 deg thermostat
4. redline Waterwetter
5. turbo blanket

anything less than 30 mins of driving gives me 175-186F..

 

Did you notice a difference with Waterwetter?

 

actually a thicker radiator could be worse.....due to more surface area causing heat soak. my buddy has a 2 inch thick radiator with 2 spal 13 inch fans and he still runs hot due to it getting heat soaked.

 

Redline Water wetter? how does that work for you

 

All i noticed with the upgraded radiator is very good cooling... of course you need an effective fan setup to blow off the heat on the larger surface area. But it was a night and day difference on coolant temp after I placed the radiator and thermostat..


oh waterwetter prolly the least that i noticed having improvement on cooling but I put it together turbo blanket.. what i noticed though it takes a longer time for the coolant temp to get hot when idling on 100F traffic

 

I run damn near the same.

I added the mishimoto radiator slim fan shroud. After I added that, everything was gravy again. I also put a 10" slim fan on the front as a pusher thats on a switch, thats on 10 months out of the year... otherwise known as summer in Houston.

Hey, Carlos, wheres that thread about your overheating problem some time ago?
