lambertpig Posted January 8, 2006 Share Posted January 8, 2006 hi has anybody had cooling probs after fitting fmic mines a uk auto and have been told things could get pretty hot with the rad being covered by the front mount? would it be easy to fit extra fan? where can i get something suitible or will everything be fine? thanks Link to comment Share on other sites More sharing options...
JohnA Posted January 8, 2006 Share Posted January 8, 2006 It's not a fan that you need, but a clean, cool stream of air --- which you've compromised by the heat rejected from the FMIC core. The stock SMIC dumps the heated air outside the engine bay, Toyota designers knew what they were doing You could try cleaning your coolant rad inside out and see if this helps. At least it would be operating at full capacity. In the summer you could use a weaker coolant mixture, further increasing it's efficiency. Link to comment Share on other sites More sharing options...
SEDGE Posted January 8, 2006 Share Posted January 8, 2006 Good duckting sorted this out for me and a smaller 8" spal fan to replace the larger one i took off. Link to comment Share on other sites More sharing options...
JohnA Posted January 8, 2006 Share Posted January 8, 2006 Indeed, good ducting helps a lot, and you can't get much better ducting than the stock setup. Unfortunately, FMIC installations tend to compromise both the intercooler and the water rad ducting. Link to comment Share on other sites More sharing options...
Alex Posted January 8, 2006 Share Posted January 8, 2006 People with radiators in an already good condition don't suffer from having a front mount...people that have compromised radiators find out about them when they fit an FMIC. DO NOT bin the stock rad fan or shroud...a radiator plate which fits from the top of the front bumper back to the front of the radiator can help the airflow go through the radiator instead of bypassing it.

Bob Posted January 8, 2006 Share Posted January 8, 2006 John, are you saying that something like the Spal fans that I've heard recommended wouldn't be beneficial? Link to comment Share on other sites More sharing options...
JohnA Posted January 8, 2006 Share Posted January 8, 2006 I'm saying that the stock viscous fan and the shroud are very good and it's hard to find aftermarket parts that will out-perform them. Even those that somehow claim higher cfm figures, depend on 'static' measurements which are useless in this sort of application. I'm also saying that there is a price to pay for ditching (or even compromising) the excellent rad ducting in front. Most supra FMIC installations I've seen are totally oblivious to the ways air flows. They are OK for show-car purposes, but that's it. Link to comment Share on other sites More sharing options...
Soonto_HAS_soop Posted January 8, 2006 Share Posted January 8, 2006 When I fitted my FMIC I had an increase in engine coolant temps of 4-5 degrees C. Still sits well below 90 degrees total. Link to comment Share on other sites More sharing options...
Paul Whiffin Posted January 8, 2006 Share Posted January 8, 2006 A really good idea is to fit an oil cooler when you've got a front mount. A good 4 or 5 years ago I was getting a lot of problems on track with water temps going through the roof. Basically when the FMIC went on I could only complete 1 lap of Donington before the temps went sky high. I then fitted one of my front bumpers which has a much larger opening into the FMIC and cooling plate which allowed around 3 laps. After fitting the oil cooler I've never had a problem since, 20 laps at a time with no problems at all. Link to comment Share on other sites More sharing options...
JohnA Posted January 8, 2006 Share Posted January 8, 2006 Good idea, the (thermostatically-activated) oil cooler would be on the passenger-side intake, right? My UKSpec has an autobox cooler there, not sure if the JSpec has anything. If not, it's a crime not to use the airflow there! Link to comment Share on other sites More sharing options...

Bob Posted January 8, 2006 Share Posted January 8, 2006 Hmmm, reading this I'm starting to think twice about the HKS S-type core I've got in the garage May have to start thinking about CW's uprated side-mount, as I'd like reliability to be at a maximum.

Paul Whiffin Posted January 8, 2006 Share Posted January 8, 2006 I was talking about track work, I've never ever had a problem with my car over heating on the road and I cant see how anyone could unless your going absolutely mental! Stick the S-type on, you wont have any problems, s-types are quite thin as well remember. Link to comment Share on other sites More sharing options...

My UKSpec has an autobox cooler there, not sure if the JSpec has anything. If not, it's a crime not to use the airflow there! Passenger side or drivers side as you'll have a big space left behind when the standard IC is junked. J-specs dont have anything in that intake correct. Another good idea for a J-spec car is an auto box cooler to keep temps down a little more. Link to comment Share on other sites More sharing options...
Pig Posted January 8, 2006 Share Posted January 8, 2006 I hvae heard of problems with R-types in the sumer in traffic. The radiator relies on the fans to suck air in but they are not powerful enough to suck air through something as think as a an R type therfore the car overheats Link to comment Share on other sites More sharing options...
Paul Whiffin Posted January 8, 2006 Share Posted January 8, 2006 I've got a couple of customers running Greddy 4 rows (the thickest around)and they have no problems with overheating what so ever and thats with std radiator and no oil coolers.

SimonB Posted January 8, 2006 Share Posted January 8, 2006 I've driven in Europe in 38C temps for hours with a Blitz FMIC before I got my oil cooler with no overheating problems. Even on track I never had a problem with water temps, although I did get high oil temps. With the oil cooler I have no problems. Of course I have a proper gearbox so don't have to worry about auto coolers... Link to comment Share on other sites More sharing options...

Nic Posted January 9, 2006 Share Posted January 9, 2006 I have HKS R-type FMIC, Fluidyne radiator and radiator plate fitted, in summer we get temps upto around 40C and I never have any overheating problems, temp gauge sits in middle, either in heavy traffic or after some spirited driving. Temps here at the moment are around 11C and I'm finding that my temp gauge is lower than usual, at around 1/3 of the way up the gauge. Link to comment Share on other sites More sharing options...
Alex Posted January 9, 2006 Share Posted January 9, 2006 Are you using a TRD thermostate too?? As the thermostate should allow it to hit the correct operating temp what ever... Link to comment Share on other sites More sharing options...
Nic Posted January 9, 2006 Share Posted January 9, 2006 Are you using a TRD thermostate too?? As the thermostate should allow it to hit the correct operating temp what ever... No stock thermostat AFAIK, it eventually reaches 1/2 way up the gauge, but takes quite a few miles to get there. Link to comment Share on other sites More sharing options...
lambertpig Posted January 9, 2006 Author Share Posted January 9, 2006 ok whats the verdict fmic or not . i must have reliability .a lot of my miles are in town. no track work.a few short high speed blasts.my temp gauge is in dead centre at present and never moves .rad loks good. dont want to spend more money on fluidline rad or additional coolers.nothing more than the fmic.should i or should i not opinions differ i am confused Link to comment Share on other sites More sharing options...
veilsideTT Posted January 9, 2006 Share Posted January 9, 2006 I have UK Auto with a Greddy 3row. Have never ever ever ever had any issues with the cooling on my car! (apart from when my rad cap failed and blew my h/gaskt:complain: ) Get that FMIC fitted and worry about it later! Link to comment Share on other sites More sharing options...
