Mishimoto 1999-2014 GMT800/900 Performance Radiator R&D

[Mishimoto]

size specifications? I am interested in core thickness, also it is considered 2 core? or single

The core is 52mm thick and is a single-pass, 3-row (3-core) design. It's pretty big

man I wish these were available sooner! I JUST put a brand new OEM radiator in my 2013 Avalanche 2 weeks ago (my original wasn't even leaking I just decided to throw a brand new one in since I was installing a brand new LS3 crate engine)....BUT I would have bought this just for the added feature of a DRAIN PLUG, draining the OE radiator makes the biggest mess ever, you are lucky if you can catch half the coolant in a bucket (c'mon GM )...looks like a great design!

Any pics of the drain feature?

I'm sorry we didn't post sooner ! I'll try to get closer images, but the drain plug itself is our magnetic drain plug. It's similar to this one, but it has a slot cut in it that allows you to direct the draining coolant.

Hope that answers all of your questions!

Thanks,

I'll be ready for one... 157k miles on my original radiator and with this new 402" LSA engine and circle d convertor I'll need to keep things cool.

Any oil temp numbers. Will you also be selling the required hosing to plumb the oil to the cooler if our trucks don't currently have an oil cooler radiator? I tow a boat and would like to be able to cool oil as well.

 

[Doubeleive]

oil cooling lines are a factory option, it takes a adapter above the oil filter and lines that run under the engine up to the radiator.

Sorry for the delayed response! I'll check with the engineer and see if we monitored oil temps. We won't be providing oil cooler lines, but as stated above, I would imagine you could find the factory parts to connect the oil cooler.

Thanks!

My OEM radiator has 220k miles on it, and the tranny was rebuilt about 40k miles ago, so I'm definitely in the market for this product. Looks like a amazing quality upgrade. I will keep an eye for updates!

Thanks for the feedback! Definitely want to keep that rebuilt trans cool We should have a pre-sale starting in the next few weeks!

Very interested here... Do you have a set of low profile fans to go with it? I ran into some clearance issues trying to run a 5" intake with the factory fan shroud.

 

[Rocket Man]

Wow raise it front $500 to $565 then discount the higher price.

Good point lol, post #14 says price will be "around $500"... Kinda funny how that works

Thanks! Unfortunately, we don't have a direct-fit fan shroud for these trucks; however this radiator also doesn't push the fans back any, so if you have a solution that's working with your intake now, you should be good to use this radiator with it. We do offer universal fans, mounting kits and a fan controller that could work for your application as well: https://www.mishimoto.com/automotive/fans-accessories.html

Hey guys,

Sorry if it seems like we're playing slight of hand with the pricing. We can't determine final pricing until R&D is finished, and sometimes that pricing does change at the last minute if a design has to be tweaked or a manufacturing process has to be changed. The last time I posted here, we were not finished R&D, which is why I could only give an estimate of "around $500 MSRP".

I hope that clears things up a bit. Feel free to let me know if you have any other questions!

Thanks,

-Steve

A few questions here:

1) Why using an old Tahoe with high mileage as a testing vehicle, not a new Tahoe with 0 mile against Mishimoto ?

2) Could use an old Tahoe with a NEW OEM radiator against Mishimoto?

3) Why not directly selling to Detriot Big 3 if Mishimoto is better than OEM?

4) Is the testing result or data verified by an independent 3rd party ?

lol, it's just like NASA over at GM, the lowest bid wins, there not going to put a better radiator in these vehicles that would put people out of jobs

Good questions! We do use a new OEM radiator for testing to ensure that there are no issues like clogged tubes or bent fins to skew the data. The Tahoe is higher mileage, but it's very well cared for and had no other modifications or issues that would have affected testing. We also installed this rad on both the Tahoe that we used for tow testing and a newer Silverado, with similar feedback from the Silverado owner.

The reason that we don't sell directly to Ford / GM is the same reason that the entire aftermarket industry exists, and what Doubeleive touched on. Ford and GM/Chevy mostly cater to the majority of consumers who simply want a vehicle with a warranty, that reaches highway speeds comfortably and doesn't cost an arm and a leg. That last requirement is the most important one. An auto manufacturer's survival as a business hangs primarily on being able to sell vehicles en masse, volume = profits. Fitting every vehicle with an engine, transmission, or, in this case, a radiator that costs more to build and only 5% of their customer base cares about doesn't pay them back enough to justify the extra expense. Even HD cooling packages usually use similar components to the standard package, with added on components that are shared among multiple platforms. Again, volume = profits.

Hope that clears things up a bit! Feel free to let me know if you have any other questions!

The most efficiency way to increase an radiator cooling capacity is increasing its size. The bigger size, the more heat exchange surface and the more liquid (anti-freeze) holding capacity for heat dispensing. To reach that, the extra physical weight adds on the truck, then fuel mileage is dropped.

Compare Mishimoto radiator price with OEM Delco one ($180 for 2008 Silverado 2500HD, 6.0L) in rockauto.com, Mishimoto price is 2.5 time higher than Delco.

Mishimoto sales targets are those truck drivers with 6 digits on their odometers, and those drivers want an replacement radiator, not a Placebo.

You are correct, for the most part. Some vehicles see greater reduction in coolant temps with changes to fin pitch / density and tube dimensions than overall core dimensions; but in this case, the core was made larger.

Our radiator weighs about 19 lbs, which is about 6 lbs heavier than the stock radiator. Adding in the extra fluid weight, the total increase in weight would be about 10 lbs heavier than stock. Sprung weight on most vehicles has the effect of lowering fuel economy by 1-2% per 100 lbs; so with an extra 10 lbs of weight, you'd see an average reduction of .1-.2% in fuel economy. At 15/19 mpg city/highway, that extra 10 lbs of weight would reduce economy by about 0.15 to 0.19 mpg. In comparison, larger wheels and tires have the effect of increasing rotational mass and can reduce fuel economy by 15-20% depending on size and weight.

Our target audience for these radiators is anybody who tows often, has significant power-adders, or just wants to keep their truck for a long time and never have to worry about replacing their radiator again

Thanks!

In my personal opinion the price point is a little high. I think at $375 you would sell 10X what you will now (at $500+) and would have problems keeping them in stock. After all, $150 to produce (maybe if that) would still be a great profit margin at volume.

Thank you for the feedback! I should also point out that our distributors will likely offer this rad at a lower price than MSRP, for those who need one after the pre-sale has ended.

Thanks again,
