Decided to pull the trigger and pick up a Mishimoto alum. rad off ebay. Install coming soon but looks like a quality piece.

http://www.ebay.ca/itm/370849850487?...84.m1497.l2649

Came with a 19lb rad cap and is just over 2 1/4" wide (see pic).

I can't personally speak for their third Gen radiators but my little brother put one his 91 Eclipse turbo about 3 years ago and its never given any problems.

Mishimoto

Great to see you were impressed with the quality of our radiator! Have you had a chance to install it yet? I am very interested in your results!

Thanks

Install should be in 6-8 weeks. Need to make a plate to mount the 4th gen fans and run the custom rad hoses.

I don't think I would use a radiator cap with that much pressure. 19psi is really high and will more than likely cause a leak somewhere in the cooling system. I usually use 10-15psi caps. It's less efficient but a lot safer.

Hey, I was wondering if you have had the chance to try out the Radiator, I was thinking of ordering one and I was wonder how you like it. How does it fit and what not thanks.

The Project

iTrader: (6)

Still working on the car so the rad has not been put in permanently.

I did a mock set up for clearance and positioning and it fitted fine.

No issues.

BLACK Z

Where did you get yours from? Are they set up with a Auto Tranny cooler? I would rather not have it in the Rad if I have a choice. IS it set up with all of the Right ports and everything?

The Project

iTrader: (6)

Got mine on ebay.

You can order the auto trans cooler for additional charge. Personally I think the trans cooler they offer is a little steep price wise.

BLACK Z

So it does not come with a Trans Cooler?

Johnny Blaze

iTrader: (15)

The one in his photos appear to have the ports for the trans cooler there.

Mishimoto

This radiator does come with a built in trans cooler.

Thanks,
Tyler

BLACK Z

The Project can you check and see if A stock Rad cap will fit the Mishimoto Rad. I don't like the idea of a 19 Lbs Cap.

Johnny Blaze

iTrader: (15)

Then what are the ports on the passenger side tank for?

I see the lower hose barb, the fitting for a heater hose, a drain petcock, and 3 additional ports, which appear to be NPT ports.

Mishimoto

Two of those ports are for the built-in automatic transmission cooler. Then there is a 1/8" NPT port which is used for the factory coolant temperature sensor, and a 1/4" NPT port which is used for a coolant level indicator gauge. Please let me know if you have any other questions.

Thanks,
Tyler

Johnny Blaze

So it Does have a cooler?!

Mishimoto

Yes.

Thanks,
Tyler

Having the tranny cooler in the radiator is not a bad thing; on the cold days it helps get the fluid up to normal operating temperature; simply add an auxilary trans cooler in-line with it if needed; I generally setup the aux cooler to be the initial cooler. Easy enough to swap the lines around if needed during the summer months.

As for the radiator cap; I agree with it being a little on the large side. It will not help cool the engine, just be a little bit of an insurance policy once you cross 260* as hot water cools better than steam. But if the rest of the cooling system is up to the task is another story. I would probably go with a standard 16psi replacement cap

interested how this works!

KITT1983

iTrader: (3)

Are they made in the USA? How are the 3 cores?

Mishimoto

KITT1983,

Thanks for the reply!

The radiator you are referring to is assembled overseas. Please understand that all R&D is done in our facility in New Castle, Delaware. We have an extremely strict quality control program to the point that we have a created a separate Mishimoto workforce to check each and every unit before boxing and shipping. Additionally, we carry a second-to-none lifetime warranty against manufacturer's defect including accident protection!

Thanks,

iTrader: (1)

what exactly are your quality control procedures and said warranty? ive had alot of bad luck with radiators not only oversears but some instates and both quality and warranty are a big thing for me to purchase something as this.

Mishimoto

All radiators are pressure tested and our drawings feature critical dimensions in order to prevent anyone from making a mistake. Of course, all dimensions are checked and confirmed in addition to the pressure test for leaks prior to being boxed and shipped out.

We pride ourselves on offering an amazing lifetime warranty against any manufacturer's defects for the life of the product. In order to qualify for the warranty, you must purchase the radiator new from an authorized dealer and retain a copy of your receipt. For complete details regarding our warranty, please click the below link:

What is the horsepower cooling capacity rating with and without electric fans?

Mishimoto

Unfortunately, we do not have a horsepower rating as that depends on many different variables such as ambient air temperatures, air/fuel ratios, timing, driving styles and much more. I am sorry for any inconvenience.

Let me know if you have any additional questions!

Thanks!

Well it don't look all that much different than my Silla all aluminum radiator but if i gotta change that radiator one more time then i may give these a try.

You gotta luv that a vendor is active and comes on a board to answer questions.

Wish more vendors did this...

I just ordered my Mishimoto Radiator today (plus a lot of other stuff), will get it next week. Can't wait for it.

On a side note, do OEM electric fans and shrouds fit this radiator?

KITT1983

iTrader: (3)

will your radiator work with my mechanical fan ?

JGM785

iTrader: (1)

Yup I just bought a mishimoto radiator too it looks the company backs up there products.

Mishimoto

Thanks for all the replies everyone!





If the shroud came on the OEM radiator, you should have no problems swapping the shroud to the Mishimoto radiator. While I personally do not have 100% knowledge on F-bodies in general, I would imagine the stock mechanical fan will be compatible as that mounts to water pump/engine rather than the radiator. There should be enough clearance for the OEM mechanical fan to fit.



If anyone else has questions, feel free to ask!

Thanks,

I have just purchased one of these units, and I'm really looking forward to when it arrives. I looked at other rads available, and I just couldn't swing the cash required for some units, and others just looked cheap. When I saw these being sold through summit racing, the quality and price just seemed right. I'll report back once it's installed.

I received my Mishimoto radiator over the holidays and installed it today (dry fit). Overall I love the quality of the radiator, the welds are superb.

Unfortunately I did run into some issues. Mainly that its not a direct fit. Ran into the same problem the guys did with the Champion radiator. The rubber mounts need to be shaved drastically to make it fit. To get the radiator to sit correctly under the shroud cover I had to completely remove the bottom rubber mounts. No ammount of shaving them would let the radiator sit properly. The uppers I was able to keep (I still need to modify them for a better fit though).

I didn't have enough time to see if the oem electric fan assembly bolts in though (fingers crossed that it will work).

And lastly as far as the ports on the radiator. My camaro has the coolant temp sensor in the intake manifold, not on the radiator. So, I had to go to the local parts store and buy a plug for that port.

MFaust89

Lots of posts about installing such radiator, and no pictures! what a shame






Reason why Mishimoto? quality, warranty and proven worldwide. I ran into the same issues of the Champion radiator install. Regarding the fans, my car is a 1992 z28 which has dual fans; I had to space the fans 3/8in to have the same gap between the radiator and fan as the factory gap (not needed, but recomended).

Note: the fans were spaced at the bottom and top mounting supports





I also had to close one of the holes on the passenger side.



Regarding the radiator cap, yes you can use an original replacement cap.




and I upgraded that too

Good info. Thanks for posting.
Im sure when The Project gets to his install he will post pics too.

Ah MFaust89, I forgot how much I love your car. Awesome write up btw.

that looks like a nice radiator.

MFaust89

or finish his car

Thanks Steve!

MFaust89, nice write up and pics.

I recently purchased and installed a Mishimoto radiator myself. I did have the same MINOR fitment issues listed above. Nothing a little bushing shaving and a couple of NPT plugs won't fix. So far the radiator has been awesome.

Debased

Does it have a spot to hook a ls steam line?

Brianbajnuth

Does anyone know the tube size in the radiator? And how much of a difference did it make towards cooling?

IROCmenace

iTrader: (1)

Not sure on tube size but it kept my car around the 195-202 mark on a low 90's high humidity day this past July. This is after the motor was heat soaked. My car was running 10-15 degrees warmer before the swap. This is on stock dual fans. I have no complaints thus far. Been in the car a year.

b4ccamaro

Guaranteed much better than the factory radiator!

Ron U.S.M.C.

Air flow, air flow, air flow.....


The more rows on the radiator the stronger the fan needs to be. Especially if there's a condenser in front of it.

That's why a stock radiator in good condition (fins not all bent over with good flow) can handle a decent amount of heat. It requires a large fan with a shroud incasing it.


That is a nice looking radiator.
