cob1980 Posted April 2, 2017 Share Posted April 2, 2017 Does anyone know for sure which is better I've been reading conflicting information? My Z overheated yesterday so I need to know whether to refurbish the OEM motors or replace with Mishimoto. Thanks. Quote Link to comment Share on other sites More sharing options...
choptop Posted April 2, 2017 Share Posted April 2, 2017 Try refurbishing first. Once you split the motor it is quite easy. There should be a post covering how to do it. Use search and it should come up. Quote Link to comment Share on other sites More sharing options...

Is there a way to test them, should they both spin up with the air con on? Cheers. Quote Link to comment Share on other sites More sharing options...

cob1980 Posted April 2, 2017 Author Share Posted April 2, 2017 Just found this for info: Start the car with a/c off = No fans Start the car with a/c on = Passenger side fan on Car running at idle and up to operating temps (190 something) = Passenger fan will cycle on and off to cool Car running at idle and exceeding operating temps (Around 208) = Drivers side will turn on to assist the other fan Anytime the a/c is turned on the passenger side fan will come on for the a/c condenser.

cob1980 Posted April 2, 2017 Author Share Posted April 2, 2017 Just tested them. Passenger fan doesn't come on with aircon. Driver side comes on when up to temp but only with a nudge. Quote Link to comment Share on other sites More sharing options...
cob1980 Posted April 2, 2017 Author Share Posted April 2, 2017 (edited) Took the fans out, dismantled the motors, none of the brushes were touching the commutator. Sorted out, reassembled, I think they are working but they are smoking a lot because I used WD40 and grease. Got a service booked next week at the Cougar Store so I will get them to test properly but ordered a Mishimoto fan shroud just in case.

tonman83 Posted April 4, 2017 Share Posted April 4, 2017 Hi Cob1980, I've just been through this saga myself, very helpful videos on youtube. Both of my fans are now working well with ac on; just need to get the car up to temp to test the cooling element. Quote Link to comment Share on other sites More sharing options...
Randy_Baton Posted April 4, 2017 Share Posted April 4, 2017 OEM fans are better than the Mishimotos - better air flow and a lot quieter. But a new set of Mishimotos is a lot cheaper than a new set of OEMs. The air flow from the mishimotos is still fine for most use though. I have Mishimotos but wish I hadn't as IMO it ruins the sound of the car. Quote Link to comment Share on other sites More sharing options...

Hello... ha saga...yes... sadly looks like the A/C one is not working too well still perhaps I didn't do a good enough job although I did notice the brushes were a lot more worn than the other. OEM fans are better than the Mishimotos - better air flow and a lot quieter. But a new set of Mishimotos is a lot cheaper than a new set of OEMs. The air flow from the mishimotos is still fine for most use though. I have Mishimotos but wish I hadn't as IMO it ruins the sound of the car. Hmm... well looks like I have to have the Mishimotos fitted now as mentioned above the A/C doesn't seem reliable and I don't want it to overheat again. I guess at least one plus point is that if you can hear them you know they are working. I notice you can buy different fans to fit the Mishimoto shroud, might be worth swapping out the A/C one for a quieter one perhaps? Quote Link to comment Share on other sites More sharing options...
