I understand you're a business man so anyone who doesn't post that mishimotor radiators are the bomb you will have something to say about your warranties.

But my rebuttle is Kia offers damn near lifetime warranties on their cars, how many guys here own a KIA?

Just because you offer a lifetime warranty doesn't mean that you will get my or other peoples business, even if you pay for the radiator if I lose my job or I can return it no charge.

People have personal preferences, and sometimes stick to brand names they know.

I have a no name radiator in my car not ebay, not koyo, not mishmoto, not griffin, or lex whatever. Just a big motherfucking radiator that does the job and fits under my hood.

When it breaks, I will probably have a specialty radiator shop build me a radiator with a built in shroud and fans that mounts to my stock grounding locations so it doesn't bolt to my upper radiator support.

Which I can't currently buy from you, or koyo.

We all have different needs was my point.

DrIvEsldEwAyS · 06-10-2009, 07:52 PM

i currently own a koyo and have never had a problem, so your saying your warranty covers out damage to them as well?

dayumm... touché haha,

Huh. I had a ka Koyo with my ka, and with my sr I have a Moshimoto. I couldn't fit a s13 sr fan shroud but I'll retry, cause I don't want to run the electric fans if I don't have to.

Why would our warranty cover damage to a brand that is not our own? Our warranty covers damage to our own products

*slider2828* · 06-11-2009, 05:57 PM

Koyo... never heard of any leakage with Koyo at all and I know 6 or 7 people personally who run them.... I rather not have the problem in the first place.... Replacing radiators is not a fun deal with fan and shroud

Too awesome!

Just emailed Chris @ mishimoto (per the sales reps demands!!).

mishimoto · 06-12-2009, 11:56 AM

Nice! Good to hear that is getting taken care of

*DreamN* · 06-12-2009, 05:32 PM

^ Does that warranty cover products that weren't purchased from mishimoto directly (i.e. tuner shops) and from a couple years ago?

If you want to speak in terms of power the engine makes, the more heat you take out with a radiator, the less power your engine is potentially making.

A stock radiator with proper shroud does fine for what most people do on here. I would get a Mish over a Koyo simply over price and knowing it wont be even close to either's full potential.

funes · 06-13-2009, 06:06 PM

I got my mishimoto rad + fan shroud the last monday and in 2 days we are going to install those good stuffs...

Wouldn't that be the job of the thermostat? Why you loose MPG with a colder thermostat.

Yes, as long as they are authorized retailers.

aa87 · 06-16-2009, 10:26 AM

Ive read mixed things about the mishimoto and the stock clutch fan. Yay or Nay on fitting the shroud?

The stock shroud fits on our rad.

DrIvEsldEwAyS · 06-16-2009, 05:24 PM

sorry, what i ment by that was, say i got in a wreck and your rad. busted would i get a new one? something of that nature, in a previous post it sounded like thats what yall would do.

Yes. If you had our rad on your car, and you got into an accident causing our rad to break, you would get a new one.

Am i reading this correctly? So if im running a mishimoto rad in my car, I get in a front end collision and the radiator gets f'cked up. You will replace it for free?

mishimoto · 06-17-2009, 11:45 AM

Yes. Mishimoto Warranty

d3m14n · 06-17-2009, 10:36 PM

that warranty is unreal. getting mine asap!

*Altered_Image* · 06-18-2009, 06:58 AM

I am finishing my swap today and have a koyo and a mishimoto... Such a hard decision! The good news is that whatever I don't put in this one, will go in my wide-body when I have enough to buy another S13 blacktop swap!

mishimoto · 06-18-2009, 09:26 AM

Good luck with your decision!

Enna · 06-18-2009, 12:49 PM

Hm seriously considering mishimoto now. I've always been with koyo... but lets see what happens.

any pics, i read in the agency motorsport special thread that they claim it wont fit an a customer said it won't fit. I am on the border of buying it however desire clutch fanaction, otherwise id go koyo.

Is it thicker than other alum rads which would make it more difficult to put stock clutch fan, aka trim a lot more??

Fits on my S14. Installation was similar to the OEM radiator with no trimming involved.

I don't have any pictures, but the rad is 3.6in thick if that gives you an idea of what you would be working with. I'm not sure what sizes are competitors rads are for comparison.

*Altered_Image* · 06-18-2009, 08:12 PM

So, I am not running a shroud on the rad I just put in my S13, I am running dual electric fans. I put the shroud on the Mishimoto that is going in my drift car (figured that if I wreck it, free new radiator). As for my daily that I just finished the swap on, I went with the Koyo. After reading all of this though, I most likely would have ran a Mishimoto on both cars, but I had already received the Koyo from a sponsor and bought the Mishimoto the same week not knowing I was going to be getting the Koyo as well.

Off topic,

I'm not sure what your asking me, but a thermostat just controls the temp of the engine by opening the thermostat valve when the water temp is at a certain temp. I couldn't tell you specifically why MPG is reduced with a colder thermostat, but it could be because more heat is taken out of the engine, or because the computer changes the AFR, or a combination of both.

Neglecting a thermostat, the more heat an engine produces, the more power it is making. About 1/3 of the total energy of the mass of the fuel in the combustion chamber becomes usable work (power to the flywheel). The other 2/3 of the energy is either taken out from the cooling system, or loss through the exhaust and other misc losses.

I was told the exact opposite by Agency(stock shroud fitting on a Mishimoto rad. i mean).
