Engine fan issues

[Pidge]

Duel spal fans are a little pricey now and iirc rogue and a guy in the US are the only ones left selling them. Some have a switch but using a configuration of relays you can run them automatically with the normal fans.



Mine was a pain to fit because it went on a Phoenix power carbon lid so can't comment on fitting to a standard lid.

Your engine bay is amazing! I will certainly be on the look out for a set of dual fans. I am looking to have it on a manual switch just in case a similar scenario to this happens in the future.

Plus I think it would be handy to have manual control of it on long drives, and to show it off, lol.

Better get saving I guess

Cheers Bud. I'll dig out the one I have, it's basically a blue version of the ones I have. I think I have a link to where I got it.

It's the panel that is hard to get. They are laser cut and hard to find 2nd hand.

Youll have to come over when you get sorted and have a natter

Another quick question ... Ive been looking at cars that have dual fans on the inside of the engine lids. Do these tend to be wired to a switch or wired into the original? Also are they a standard fit and where can I buy them from?

The KO Racing Dual Fan Kit that we stock is normally wired into the exisiting fan circuit with relays, but a manual override switch can be added. They are a standard fit.

Of course! My bad Peter I forgot you did them too

Do you mean youve got a spare set of fans kicking around?
I presume your still running an mr2, and not just breaking it?
It would be great to meet up and have a proper chat/gander at cars. Time dependant im hoping to have the car fixed next weekend. Its running atm but obviously Ive got the issues with warning lights and engine fan.

Your always welcome over mine. Could go for a quick drive ... Or replace my alternator and then go for a drive lol

Damn good spot, thanks

Almost managed to buy it. The finalisation in the thread is a typo, unfortunately the person who posted in the ad first got it

Hence I'm still on the look out for one...

Did you sell your spool fan set-up?

Do you have a photo please mate?

Do you think that I would be able to keep the rain tray and mount this fan on its own between the tray and lid?

So you will still have an MR2 then? When is it going to be road bound again?? - just wondering if when we meet up I should be bringing the merc or the mr2

[Pidge]

I'll have to dig it out of the garage when I get a sec. It's coming off the road on Saturday and will be back on the following Saturday.

Yeah will still have one, Bring the merc and you can do some prep if you want Also get the bucket seat if you still want it?

Right bit of an update today...


Took the fuses out and tested them; all ok

Tested the ecu using the below as a guide and all tested ok. I didn't test the sensor either as I presume this is working as the fan light only comes on after the car reaches temperature:



Couldn't get the cable off of the fan in order to test it however the fan itself is flowing freely

Also tested the battery today;
With the car off it is showing 12.4V
With the car on before accelerating its showing 11.8V
With the car on after accelerating (and the car returning to a normal state) its showing 14.7V

I think the alternator is some of the issue. Another one has been delivered for me today

Still not convinced that the alternator is causing the issues with the fan though...

From the video you definitely have an alternator/belt issue. Note the instant your in dash volt gauge jumps up to the normal level after revving, the classic 'alt failure' lights go out.

I replaced the belt less than 80 miles ago, so its definately not that. I'm inclined to agree with you that the alternator is the issue, and this will be replaced this weekend hopefully. Fingers crossed that solves some of the issues.

Would a dodgy alternator stop the engine fan from working though??

Just wondering if you managed to grab a photo of this mate?

Are you going to Japfest on May 12th? Twould be good to see you there
