That is not true. I just claimed a warranty on my mishimoto based on pictures I sent to them. Their customer service is second to none.
Be careful when slashing some other companies reputation.

Yep did see Joes comparison video, was looking at the Stant 180 normal. I dont think there is anything wrong with the super stat just that it takes longer to open and does not open as much.

Will this thermostat come with a hole in it already for those that have used it?

He very clearly said that he wished it was not true. Implying that it was true. That he'd seen it happen.

Hello Everyone

Hope you are all having a great day. I saw our warranty mentioned in this thread and thought I would clarify a bit of information.

Mishimoto does offer a Lifetime Warranty for every product we manufacture. One completely optional step in our warranty is to offer a bottle of Mishimoto Liquid Chill Stop Leak by K-Seal. As I mentioned this step is completely optional and can be skipped if the customer desires. We have found that some customers actually prefer this method as there is no need for removing the old unit. In some instances customers have extremely small leaks, maybe a few drops a minute. Labor can be quite expensive making this the more cost effective option.

If the customer chooses not to use this step we move forward with a replacement radiator. I hope this was able to clear up any questions or concerns.
Thanks

For realz? They really do send out stop-leak? I'm not sure he was advertising.

Just wanted to follow up with this. So it turns out the real reason for my over heating was i still had air in the cooling system. One good bleed and its much better. For comparison; before i would be 95C while moving and when i stopped within a minute i would be at 102C and fan on non stop, now i am still 95C while moving and when i stop within a minute at 97C and fan cycles on for like 20-30 seconds then shuts off and temps come down and it really takes a while to get to 102C prob over 15min of idling but still rad fan cycles on and off and temps come down. So no more over heating.

I'm still wondering if i should install a 180 thermostat. Currently my operating temps are 95-102C or 203-212F. Would i be better in the 188-193F range which is probably where it would be with the 180 thermostat?

Oh my....
You shouldn't be creeping to 102c. I can sit an entire day and not go past whatever I set the fans to. Get another fan.

Your problems make more sense now.

A 180 thermostat wouldn't hurt, I run one on my car. It allows the radiator, and the fans, to get ahead of the cooling needs earlier in hot situations. A single fan should be able to cool your car, given that the fan is beefy enough, *and that your radiator is beefy enough. I am using a single spal fan on my TSE radiator, and last track day (100F ambient) my temps never went over 186. The fan was not (and should not be) needed for track cooling. I'm not sure atm what fan(s) you are using, but there is a vast difference between random fans and real fans. I will list some spal fan part numbers here for you. These are the fans that FM settled on after doing their fan shroud radiator draw through testing. What that means to you, is that these fans are tested, in a miata cooling situation, with radiators etc in front of them. These fans pull some air.

As previously mentioned, the thermostat sets the minimum operating temperature of the system. It will not change the peak coolant temp. It may help you some, in that the ramp up time to peak temp may be longer, and average temps may be lower, due to starting lower. But, if you are heat soaking due to not having enough thermal capacity in the system, you probably will not see that benefit. In any case, it won't hurt anything, so try it if you like.

What is the recommended fan on temp with a 180 thermostat.

Mobius

iTrader: (2)

Good question. I'd say set it for 190, cut off at 186. This would allow the thermostat to open fully, and full flow be happening. At highway speeds, airflow should be sufficient for the radiator to keep things cool below fan on speed. Or, you could set it higher, say fan on 200, fan off 194.

Joseph Conley

I second the fan on at 200 and fan off at 194. Been using those settings all summer. Fan only comes on setting in traffic or moving at < 10 mph for extended periods. If I'm moving my temp sits right at 185.
