Quick question about the thermostat. My old one locked up and my car heated up abit. Should I buy a new one and replace it or should I leave it without one. I've heard from some people that going thermostat-less is good cause the car doesnt heat up much, but then again this is a rotary not a piston engine, I've heard of it in PE but not in RE, what do you guys think?

And also, should I switch from a clutch fan to an e-fan? I know it supposely gives me a couple of more HP, but I dun care about that, what are the pros and cons about having an e-fan? Will it be reliable?


Please get back to me

OHHHH the search button is broken???? because your questions sure have been covered quite a few times...

If you had used the search button in the upper right hand corner of the page you would have found:

Do not ever run without a thermostat or restrictor plate in a rotary engine.

Only use Mazda OEM thermostats

E-fans do not provide you with any additional HP, as any gains you might get back when the car is warm, are lost again, with the high increased load on the alternator and electrical system. In addition few E fans pull as much air as the stock viscous fluid clutch fan and any real replacement fan needs to pull at least 2600 CFM to even be suitable for the FC.

gas milage will suffer without a thermostat, possibly running richer. I wouldnt advise it. There are different temperature ranges for thermostats if you'd like one slightly cooler, go up to your local parts house. oem temp is 195* F


regarding E-Fans, I think I read somewhere that the fans for a Fiero are sufficient for an FC?

Alright thank you both, and I wont be a dick and answer rudely back to Icemark. Again thank you both for answering my question. I didnt do a search because I wanted a fast reply because Im about to go down to the parts store. Goodbye

DO NOT USE AFTERMARKET THERMOSTATS IN A ROTARY ENGINE. ONLY USE MAZDA OEM THERMOSTATS.

You will have problems if you use an aftermarket thermostat (like a Stant- which was not designed for a rotary engine operation, but simply fits).

Icemark, how much does a Mazda OEM Thermostat cost?
And I can get it at the Mazda dealer I presume?

Icemark

$10 to $15 USD at Mazdaformance online, or any Mazda dealer

xvampyrex

Alright, Thanks alot you were a big help, I guess I'll wait till tommorow and just head over to the Mazda dealer.

I really dont see how an oem thermostat will differ... what is different about an oem one?

Icemark

No one can search today???

Okay...

#1 Aftermarket Thermostats generally don't have the bypass hole

#2 the cheap aftermarket stant crappy thermostat that people buy at the auto parts stores, tends to jam and fail around 6 months (although I did hear of one lasting 2 years once), because of the crappy cheap metal they use and the way the cooling system works on a rotary.

#3 It has been proven over and over and over that using a non OEM thermostat, the water temps are typically higher than when using the OEM thermostat (even though many aftermarket thermostats claim a lower open temp.

#4 because most aftermarket thermostats are not designed specific for the rotary cooling system and tend to be one that fits, the flow tends to be restricted.

And the OEM thermostat is 180F not 195F

Well I apologize for asking a simple question while we were on the subject... Since I found out a couple things you're clearly unaware of, judging by your responses to both myself and xvampyrex, I doubt it'd make a difference... I guess your post count reflects on the size of your ego.

#1 watch the flaming. Regardless of that I am an moderator; Acting disrepectful or insulting to your fellow members (any memebers) is considered flaming in this section.

#2 this whole subject is covered quite in depth in countless threads. Being new I can only assume that you have not read the sticky threads at the top of this section including before posting.

To keep from repeating over and over the same questions you must use the search function found in the upper right hand corner of this page. Often the same question has been asked countless times before and there will be several threads on it both here and in the 2nd gen archive. This way is much much quicker for a response (looking it up yourself) than posting and hoping that someone has enough intrest to answer the same question again.

#3 I guess it is a good thing that my post count shown is actually considerably lower than it really is. For my ego I guess.

Maybe you should lead by example and not be disrespectful of members, even if you are a moderator. Maybe he didn't know what terms to search with.

HAILERS

So??? My ego is going to get even bigger if I post more???? My, my, new hat time is here.

Hey, give him a break, this is his job, to stare at the same questions day after day. Obviously it's affecting his testosterone levels and making an aggressive-compulsive personality even worse...

please read this sticky before posting:

ATTN new members, read here before posting, Check the archive, FAQ & use COMMON SENSE

It can be found here: https://www.rx7club.com/showthread.p...threadid=59758

And I am sorry you feel that sarcasm is disrespectful... I personally think people that can't bothered to help themselves as pretty disrespectful and shows a sense of being selfish.

But since this subject has been answered and is now way way off subject I am closing this thread.
