I’ve just bought the same kit, but i was waiting to your’s video to instal it, i will write you a comment when i instal it
Have you tried installing it ?
Driven by madness not yet, i think next week-end, if it can help you it will run with an oem radiator and thermostat
Hey mate could you just get a lower temp fan switch?
I recently bought an RX8. Replaced the radiator with an all aluminum one and still running above 200f. Ordered one of these kits and will be putting it on tomorrow. Hopefully it’ll help out.
Any luck with the kit?
Driven by madness Well I installed it and noticed that the fans would kick on around 190-195 and not the claimed 180-185. Yesterday I spent the day replacing my radiator with a Koyo after thinking maybe buying a cheap eBay radiator wasn’t the best thing. I tried relocating the relay kit the fan kit to where RB recommends but the hose is too short and you have to buy some adapters to make it work on the bigger hose. So I followed that hose to the other side where it would work better. In doing so I broke off both of the electrical connections on the sensor as I was fitting it into place and tightening down the clamps. Going to try and solder the wires back on to what little connections I have left and hopefully that works. If not then I’m out $100 and I’ll have to order another or figure something else out.
Ohhh boy, i feel ya. Keep me updated on it man, hopefully i'll manage to make it actually work.
This mod worked for me, sometimes you need a drive cycle for it to start at the right time.... On the other hand, it caused my fans to run most of the times which resulted in a fan connection to melt, stooped the fan, engine overheated and coolant seals failure.
.. currently in the middle of a rebuild due to it.... Don't blame the kit, I didn't have the right monitoring. But definitely passes a bill on fan life span...
The hose you've installed the adaptor in is the return pipe to the water bottle. Do a Google search for "RX8 Racing Beat water sensor guide", and on their page there is a link to an installation guide. Use this guide to locate the hose you should be using for an accurate coolant temperature reading. Enjoy!
THBandit6 why would they tell you to install it there then? Do you have one installed on the heater hose?
This hose doesn't have a constant flow of coolant through it. The tank is the highest point water can collect in the engine bay. If it wasn't then having the coolant level markings on the side would be pointless. Some companies utilise the heater hose (like Racing Beat), others provide a coupler that you'd fit in the radiator hose itself (Essex Rotary). These are preferable positions as you constantly have water flowing through the cabin heater core, and will have fluid flowing through the main radiator hoses once the thermostat opens, so once warm you'd then get an accurate reading from the latter. 200F isn't overly hot unless that's when you're cruising at a stead fast pace on a highway, in which case I'd expect it to be lower depending on ambient temps. 200F around town or when press on on backroads isn't unheard of. For reference i have a RB one installed in their recommended location which works flawlessly.
THBandit6 I just tried to install my fan kit on the heater hose but the included adapter is too small. The heater hose is a larger diameter and won’t work. You might be able to buy the RB adapter and screw the relay sensor into it.
Like Christopher said, why would they recoomend that position if it's know not to have a constant coolant flow... I'll try and relocate it on another hose, preferrebly the racing beat one.
Make sure you don’t have any coolant leaks anywhere and fill up the resivoir with more coolant if low... if you think it’s the thermostat take it out put the kettle on grab a bowl and a thermometer and pour the hot water into the bowl with the thermometer and drop the thermostat in. Should be around 82 degrees Celsius when that opens...
Not the thermostat. On his first drive it should have overheated already. See THBandit6 response below to know the real reason why it was like that
Just do a ECU remap to activate fan at lower RPM. In my JDM spec, low speed kinds in 95c and high speed starts at 100c. That’s way too hot. I’ve remapped it to 85c for low speed and 92c for high speed. No wires cutting or what so ever. Clean like stock.
Thanks for the feedback! After so many people telling me to remap it, i'm seriously considering getting the Mazda edit or similar, and start learning how to utilize it.
Dude, seriously get Mazda Edit and you can choose when to trigger the fans without doing all this, those kits introduce more chances for leaks and failure....
hi there. where do I get mazdaedit? thanks
Mine works like a charm, keeps my car at 85 cruising like you do in the clip with original fans and radiator. Does throw a "cooling fan 2 control circuit" code though. I think you need to drive the car to get coolant through that hose.
Just drove the car for the whole day today, and nothing happened. I saw the reservuori filling up, but nothing happened... i'll re check all the connections on the sensor to make sure nothing is broken or having a bad connection
I just ordered the obd2 scanner, thanks for the link 👌
No problem buddy 😄
You have to bleed the air out. Might take a couple of heat cycles do do naturally. Have the same fan mod on my car. It works excellent!
There is no air trapped in my system... I bleeded it out 3 times, and nothing came out anymore.
@@Drivenbymadness there is because ,not is the BEST place, so...why not put the new water sensor on the trothle body tube of water,also you can remove the tube from the trothle body and conect directly in the new water sensor fan, in this line we have coolant from the first start and make sure you can leave the trothle body tube out if the weather in your city is not as cold as -4 degrees, then you will have gained extra cooling with 2 simple mods.Cheers
@@TheLaccarazy is there a place to have this installed - my son has an RX8 and I think this will help him
@@karen30092 I'm sure a shop could do it but it'd be better for you and him to do it yourselves since it's not a terribly difficult mod to do. A shop might just overcharge you for it
Mine is the same make & it works fine.leave the hose where the fan kit goes off start car & see if water comes out it might just be a air lock
Hey mate, I'm running from 94 to 100 degrees C in town (traffic jam). Is that temp fine? Or should I get a new radiator + fan control? Thanks in advance. From your "twin" country, Slovakia :D
I have this mod’s and si great in the carebean where the climate is over 85f all time. The problem is the location od the temp sensor, this hose is For transfer bubbles to the reserve tank. I have analóg temp clock whit the RB adapter in heater hose an the fan activated St 204 f an turn off St 180-185f
I Need your help. My Check Engine light is in and i got the code p2270... what Should i look out for?
p2270 suggests that you likely bought the wrong O2 sensor from ebay, if it is a new one in there. If not, try googling the code :)
I have this kit installed mate and have had 0 dramas with it. Worked first time and has done since. I would recommend check for air in the system. Wouldn't hurt to ask Scott from Rx8 Performance for any ideas also. Hope you get it sorted mate!
Thanks mante :) Already asked him. Currently troubleshooting every small detail. Glad to hear you had success!
I’ve installed this kit of two RX-8s and it worked perfectly in both cars right away.
You need to make sure you have enough coolant to flow thru that upper hose and cycle in the reservoir.
When my engine is running, there is constant flow in the tank from that upper hose.
man i said to you thats not a good hose for measuring the temperature 😂 i think racing beat have better location to measure the temperature
I know bro, but i wanted to do it like the instructions say, so if someone runs on the same problem, he knows how to solve it :) Yes, i know about the racing beat position, and it's a good one allight :)
Why bother all this trouble, kit, hoses, relays, really why do it if you just can get someone tune it? Just get a different setting in the ECU tune, did mine with 10 degrees lower temps to start the fans.
Im currently downloading mazdaedit and ill start doing improvements from there on :) from an experienced owners perspective, this seemes the best way to go. Thanks for the extra kick, it was time to take it up a step 💪😊
I don't see a link for the control fan kit. I want one for myself
I DiY'd a button in the cabin and grounded the 2 relays. When its hot outside it will keep 82 C° with the fan always on.
Attila Nagy info please???thanks in advance
@@athanasioskristianpapanico1959 basically you need to ground the 2 relays of the fan. Email me K3ntclar@gmail.com and i'l send you some pics
+Attila Nagy can you please send me info? sakisw@hotmail.com
Have you considered an electronic water pump?
I had yes. Maybe it'll be a mod that i'll do next year. I am planning to replace it anyway.
I would bleed the coolant some more,as coolant definitely came out of that line when I cut it for the kit.
I wish I knew what you know what it comes to this car. I probably am killing mine.
Naah, don't worry man, regular maintenance is key. If you have some more questions about working on it, feel free to contact me on my social media or website :)
Hmm "plot twist" for the video.. let us know wth is going on xD
Good video man, I had to sell mine a few days ago 😭
Thanks man! Sad to hear that, but hey, we all need to move on to new adventures! Otherwise life gets boring :D
Does this give you a check engine light? I read online that it did for someone
No
Why didn't kit work need to know if I should buy
It worked after I modified it. Here the video ua-cam.com/video/EwPmPqC5seA/v-deo.html
Air inside mate 100%
Triple checked and tried evacuating air again. No air is in my system.
@@Drivenbymadness did you find the problem?
@@SnipingWithSkillz tomorrow I will take the sensor out, put it in a separate tube and pour in some boiling water to simulate coolant flow, and if it does not trigger anything, there's just nothing else to do
Looking at the place the hose is connected to (top of the overflow tank) I suspect that there is and should not be any coolant their unless the engine is way to hot or there is to much coolant in the system.
i would put it somewhere close to the engine. Maybe the feed line to the heater core?
That's what i'll try to do in the next video :) I'll go for a ride, to see if that's the issue, and if not, i'll relocate the sensor. Thanks for the feedback bro!
I think this mod is shit, if the fans does correctly the job there is no reason ; install it on hose between the top radiator and the coolant tank will be better.
Did this kit few weeks ago ,fans are on sooner and go off sooner. And it doesn't run for 10 minutes after you get out of the car.
I recommend getting Versatune
After some similar comments, i'm seriously thinking of getting a tuning software ike the one you mentioned or Mazdaedit. Thanks for the tip :)
Awwwwwwee, tease.
Hehehe :P
I think that hose is just for return of coolant when it goes past a certain level within the system. It will be bone dry unless you drive aggressively imo. That's the point of the coolant "OVERFLOW" bottle, no? So that coolant that's overflowing from the system could return to the bottle and back into the system via that hose and via the hose at the bottom of the bottle.
Whoooo there cowboy :D I know the role of that hose, but the instructions of the kit say to install it there, and the people that installed it on that hose actually made the kit work... So the question is, why isn't it working on mine. That's what i'll troubleshot in the next video :) Otherwise, i would've installed it on the racing beat hose position, which would've made more sense.
Comment number 8!
Damn right it is bro! :D
