Thanks for answering our questions! Just keep in mind, we are doing our best to help troubleshoot potential issues. As noted, we have not had any customers experience similar performance concerns, so we are curious as to why this is the case with your particular vehicle/situation. Our team is in no way trying to push your concerns to the side, we just want to understand why this could be happening and we appreciate the assistance in troubleshooting concerns.Hi @Mishimoto
I will be answering your questions in order:
I have a Treadstone IC kit. Those who have it will agree with me that it is roughly the same size as the Mishimoto one (same mounting style). The crash bar is still in place and the core itself is sitting right below it.
This intercooler is not big enough to have any sort of blockage of the radiator whatsoever. I've installed the radiator and the intercooler kit at the same time. I am happy with my IAT temperatures after the install because before I was in fact getting heat soaked, so the intercooler upgrade was not worthless; the highest I ever see now is probably 20-25*F more than the ambient (driving in the city), I mean my screen shorts speak for themselves. The IATs increase with the coolant temps; once the coolant raises to 200* F and above, the same goes for IATs (~130* F)...
Ok so, the bottom of the radiator is roughly on the same level with the top of the crash bar (if looking at it from the side). The intercooler sits below the crash bar; therefore, there is no blockage there.
As I've mentioned in my earlier posts, fitting the radiator took me the most. All together from start to finish, installing both products took me 36 hours. The part that had to be trimmed off on the radiator has zero effect on its performance - it's just a mount that was on the way of IC pipes.
Also, watching the official YouTube install video where that blond, pro drifter guy does the install (not that I really had to watch the install video, just did it out of curiosity), I do not recall him putting the OEM intercooler back in place after installing Mishimoto radiator/intercooler. Now, some people can do that if they want to (or if they keep the stock intercooler), although I think this step should be completely optional. For me it's not even applicable because of treadstone's intercooler pipes - there's not enough space - that's one; two, I prefer getting rid of the OEM equipment if it's not being used. Yes, it will result in open space right under the radiator and the fan shroud not covering anything, but it is fixed and sealed (posted earlier). The shroud performs as it should.
Another thing were the airdams which I threw away accidentally, but I ended up making my own (as posted earlier) which are larger. Even though I believe these pieces hardly do anything at all, I still decided to go ahead and make some - so that will be out of the way as well. So, I made and installed them and noticed no change in coolant temperature at higher speeds...
@jesse82nc said that I should start worrying if my coolant gets over 220* F, well guess what, in some cases I am only 5 degrees away from that - I don't want to risk because I've NEVER EVER had 200+ degrees with my stock radiator and I sure will go back to it if I have to. The good thing is that our ambient temperature isn't even that high yet; I wonder what will happen once our temperature will get to 100+...
I look forward to have things worked out as soon as possible. No, I am not going to have an e-war here; we're all adults and this situation should be taken care of accordingly. I know it's hard to keep everyone happy, but hey, it doesn't take much to make me happy in this situation - I just want to get my money worth. If I still had the original box and didn't have to trim the radiator - I sure would return it... Although in this case I don't know - I could be still eligible, so.
I apologize for the inconvenience you are experiencing. Our CSR team recommended reverting to the stock cooler in order to help troubleshoot the issue. Like I noted before, we have not had a similar report of performance concerns which is why we are attempting to diagnose your vehicle.Received a response from Mishimoto this morning:
Well, of course they are curious about my intercooler, probably mainly due to it not being Mishimoto... Do you know why I had to cut it? Because you guys decided to put that half inch gap between the rad and the AC condenser? If it was sitting flush mounted to one another just as OEM - I bet you I could even reuse my stock coolant reservoir but because it is what it is - I am forced to look for another one. How about the grill area? Is the opening there not enough to cool the rad? I highly doubt there's not enough air flow just because I now have a FMIC; the air still passes through. Look at @PeanutButter - same setup as myself with the exception of OEM rad that he still has AND still has better coolant temperature than me with your radiator.
I've already killed my Friday, Saturday and Sunday installing this, and sure ain't going through this again. I mean seriously?? You telling me to put the stock parts back on? The only stock part I consider reinstating is the radiator because the one from you obviously isn't doing any good.
@PeanutButter is your man in this case - again, same intercooler as me and stock radiator. Can you explain why he has "enough air flow" to cool the stock radiator?
+1 what blyatt is saying...
I also sent a message to Mishimoto customer service. I asked what shall we do now? As I said, if no other radiator will be provided, this one needs to go back and my money's got to be refunded. I do not see another way to solve this problem.
I spoke with our customer service team today in regards to your situation. If you would like a refund, we will certainly honor that request. Please contact the representative you have been working with to initiate this process.Nope. No updates. I had to get on mishimoto.com and have a chat with one of the reps. They promised to get with me today... We'll see...
Interesting. This radiator does not typically require trimming of the factory hose setup. I assume this was the stock hose on the lower side?Another thing to note is that I had to shorten the radiator hoses because of radiator thickness... The upper hose I had to cut anyway, so I could insert the 38mm gauge adapter but the lower one kept bending without cutting. I had to cut a good amount, so it wouldn't bend otherwise it would affect the coolant flow.
Because I am going back to stock radiator this weekend, I would no longer be able to reuse my lower hose anymore due to it being too short, so I just ordered a new one off rockauto and shelled out $30... Kind of sucks to having to spend more money...
That is correct, I've installed two things at once. On one hand, I understand you have to ask me those questions in regards to Treadstone's size and how much space it takes behind the bumper under the crash beam, but on the other hand - the Mishimoto intercooler takes just as much space (maybe a little less), but is the different really that significant? I don't think so...Our questions in regards to the FMIC install were asked because you did quite a few upgrades at once. This introduces other variables that we wanted further information about. The Treadstone cooler does appear to block the entire portion below the crash beam while the stock cooler sits slightly lower. That being said, the slight difference here is unlikely to cause significant impacts on temperatures. Others seem to be experiencing normal fluid temperatures with this exact cooler as well.
I understand; however, I would have to agree with Blyatt, I just simply will waste my time by going back to stock intercooler just to see if your radiator will start functioning. Second, I mean, why? We have @PeanutButter which has the configuration your CSR team wants to see. I am thankful that he took the time to post his temps. Thanks @PeanutButter.I apologize for the inconvenience you are experiencing. Our CSR team recommended reverting to the stock cooler in order to help troubleshoot the issue.

That's great. I will send an email and see how we can go regarding the return process. As I said earlier, I am waiting for the coolant hose I ordered yesterday and until I get it, I will not be able to do anything.I spoke with our customer service team today in regards to your situation.

Yup. If I did not have that 38mm hose adapter, I would most likely had to trim the upper hose as well. The lower hose definitely had to be trimmed because the Mishimoto radiator is spaced out closer to the engine, therefore, the hose was too long and had to be shortened; otherwise, it would bend and cause the coolant flow to be decreased. New hose with shipping is $30 from RockAuto as it is not sold locally anywhere.Interesting. This radiator does not typically require trimming of the factory hose setup. I assume this was the stock hose on the lower side?
I thought it has been proven that Water Wetter only works properly with 100% water. It's made for those that need to run 100% water at the track due to track rules. On 50/50 mix, it doesn't do much at all.Since I ordered some Water Wetter with my Redline tans fluid When I did my Clutch install this weekend I flushed my Coolant /Radiator and added Fresh Peak 50/50 with 4 caps of Water Wetter and on my way to work this morning from my dash temp gauge it looked like it was running slightly cooler so Im going to log the temps on my phone on the way home....its very humid here but only 61 and doesnt appear to get over 75 for the next week.
That's actually not true. Otherwise there wouldn't be videos on the internet of people taking hammers to their Mishimoto radiators after months of fighting with your customer service on the poor performance of the cores.Thanks for answering our questions!

Is that with your stock rad and those massive CFM fans @jesse82ncSince we have been having some very warm temperatures here in NC the last couple days, I thought I would update.
All water temps are from my Prosport Evo gauge with the Sender in the upper coolant tube from the radiator.
It was 95F on my way home yesterday, so I had the A/C on
Drove at about 60-80 mph for about 20 minutes, developing some boost up to about 8-9 psi a couple times (3.8T)
Then encountered traffic
While sitting in stop and go traffic for about 10 minutes, and never getting above 20 mph, the temperature crept up to about 215F, at one point it hit 220-222F
I turned the A/C off and it got down to about 215F and stayed there.
As soon as traffic broke and I got back up to 70 mph, the temperatures dropped back down to around 200F.
After about 15 minutes at 70-80 mph, It was down to 185-190F or so.
The 222F was pretty high and worries me a little, but it was very hot out and we were not moving, and I had the A/C on. Both fans were going at the time, but I guess it's barely enough air since my FMIC and Mishi Oil Cooler are mounted up front as well.
Oil temps were around 220F as well for reference.
The OEM/Dash engine temp gauge never got above 1 notch below the middle, so the ECU was still saying everything was alright.
Using my OE ECU, I was able to measure a difference between straight 50/50 and 50/50 properly blended with WaterWetter, only 6* iirc, but it was enough to make me want to add it to both my intercooler and my radiator.Yup, that's cause the coolant/antifreeze will make the track slippery if it gets on the ground. I also thought it only works with water; some forums say distilled water only.
Let's not even go there LOL... I am yet to see any improvements from a brand new 50/50 mix; I guess I'll find out once I put the stock rad back on.Didn't know that. Now I do thanks lol looks like I wasted some money. Maybe it was just getting rid of all the old coolant and putting fresh in then that made a slight difference.
Ya... Next time we will get 61 is in October or November :| Your idle temperature is lower than mine on the highway :frown: Did you ever seal the hole?So ya after putting fresh coolant in today on my way home from work it was cool 61 outside but none the less 30 minute drive with AC on for 5 minutes or more and stopping and going at stop lights and even getting up to 100mph on the highway I never saw my temp reach over 193. the 193 was sitting at a stoplight with the AC on. On the highway cruising my temps were around 173.
6* difference would make my eyes happy for sure... Especially in my case.Using my OE ECU, I was able to measure a difference between straight 50/50 and 50/50 properly blended with WaterWetter, only 6* iirc, but it was enough to make me want to add it to both my intercooler and my radiator.
Ah, well in this case welcome :grin:Mishimoto Radiator.
Well as snoopy said the water wetter added to 50/50 does help slightly more which my temps did read around 6* lower in general. And LOL did not even think about your situation when I typed that, I suppose the $10 I spent does not even come close to the $300 you wasted.Let's not even go there LOL...
