stock fan question

[gsx4357]

is there a slim fan out there that can blow the same or better than the stock fans? i live in phoenix and i could use the extra air flow if possible...if there is a slim fan that is better,,,on what site can i find them on? im trying to get this done before summer hits as well as the 120 degree weather

Mostly all slim fans will flow more than the stock ones. Check ebay.

Yea I got 2 10" slim fans and used a washer with zip-tie to mount them and then wired them in to work like stock.

2 10" Fans were $35 shipped

seriously check out mishimoto, high quality for a reasonable price and cooling is something they specialize in.

they also come with shrouds, but the price is a little steep, i don't know about you, but you must be big pimping. but as they say you get what you pay for. you can get ebay ones also that will work for a couple of year. i'm just scared to use them, they might melt.
im not a high roller, but i saved up 100 bucks from each pay check to get the mishimoto's

Not even close. Unless you get the top of the line (very expensive and not that slim) slim fans, the stock fans actually flow a lot more air (almost twice as much as the ebay/cx fans). The only reason you should be switching to slim fans is if the stock fans no longer fit, generally due to an oversized turbo, at which case you will have to work with a less then ideal set of fans. I had slim fans for a while and ended up going back to the stock main fan as an upgrade.

I'm in El Paso and it gets almost just as hot here. I used to have overheating issues (both a cruise and idle) until I overhauled my coolant system, now it never overheats. Look into these things rather then the fans. The stock fans are actually really good!

• The ebay style slim fans (that come with the PR/CX radiators) flow about 900 cfm which is considerably less then the stock fans, which flow about 1600 cfm.
• Another issue common to modified DSM's is that we remove the ducting from the air dam to the radiator and stick a big ol' FMIC in front of it. Now not only is the ducting gone so the air isn't being directed to the radiator but the air is actually being blocked by the FMIC. Consider making some ducting to route the air that passes through the intercooler up into the radiator.
• You can try lowering your water/coolant ratio (especially in the hot summers) from about 50%/50% to 70%30%. You can even throw in a bottle of water wetter if you would like. Also with the coolant make sure the system is FULL with no air bubbles and the reservoir is also full.
• Check your thermostat to make sure it's opening and circulating like it should. You can also try a slightly lower temp thermostat, especially if you have an engine management system with a coolant offset feature like ECMlink (only controls when the fans turn on with 2gs). 1g's came stock with a 195* thermostat while 2g's came with a 180* thermostat.
• Replace the coolant fill/radiator cap (OEM is 0.9 BAR) Mitsubishi part number MB660735. If it is leaking (the rubber seal with get brittle and not seal with age) it will lower the pressure in the system and thus the boiling point of the coolant and can cause overheating.
• Lastly if you do everything else and are still having overheating issues, a compression and or leakdown test would be in order to check the headgasket. Compression and Leak-Down Testing

Hope this helps!

Add Redline waterwetter to your coolant, it will make your engine run cooler.

You don't need some expensive water wetter, just use a drop of good, strong dishwashing detergent like Dawn or Palmolive if you really think making water "wetter" is gonna do anything. Wetting has do to with surface tension. I see it doing nothing for cooling, especially when the surfaces that cool aren't even largely hydrophobic in the first place.

 

[kmarttalon]

i have never heard of using dishwashing detergent in my radiator will have to look into this wow

Stock fan's are way better then those slim fans imo.

 

[phunny]

Slimline is junk.

I also went with a ducted setup and if I set a box near the FMIC it will get sucked to it and hold there.

I was having severe oerheating issues with a new turbo/manifold setup in 100+ degree weather. I tried ebay fans... slim line fans with no luck. As soon as I installed the spal fans the issue went away. Hands down spal is the way to go but they are on the pricey side but in the end.. you get what you pay for.

The stock fans are good. Maybe you can look into a new radiator.

I would have thought that a new aluminum radiator was already installed... if not.. thats the first step... or at the very least a complete coolant flush.

best answer hands down. try using google to find fans not ebay. i mean ebay is good and all but cheap listings+ebay=bad news usually. then make another thread asking about the different fans you found for your dsm,or even make a poll for the best bang for your buck so to speak.

@9!'clipseDOHC
Curious how you found the cfm rating for the oem fan.

I've been looking.
