R32 GTR

mods to cooling

aftermarket radiator 42mm or 52mm not sure

16inch thermo fan comes on at 75deg

the stock overheat fan in front of the condenser also comes on at 75deg

normally i don't have a problem

but she has been getting up to about 95deg on freeway cruising at 3000rpm

but has no problem keeping cool at the lights temp even starts to drop.

Built motor

stock water pump

have Nismo low temp thermostat on its way.

i have heard of people having trouble keeping there cars cool with thremo fans but this seems strange to me!

thinking of getting a radiator air guide.

any thoughts???

I had a similar issue, the thermostat was stuck halfway.

Took forever to warm up, idled hot at the lights, coolish on the highway.

Put a 87 degree thermostat in and it sits on 84 degrees all the time.

Fan should be set to come on at around 95. Thermo fans only need to run when the engine overheats. If you want one that works most of the time, put the factory fan back on.

Did you refit the "stone guard" under the radiator?

I was going to say fan clutch but you dont have it..lol

bleed the system and have the heater on full heat mode at the same time, the airlock can be in the heater core.

electric fans aren't the same effectiveness as the factory one. make sure you fit a shroud ??? front of it and behind the radiator to force the air over the fan not around it

system has been bled a few times

thermos are wired fine

thermos are on radiator so don't need a shroud as it would do nothing

don't have a stone guard

might have to try bleed really well when i fit the nismo thermostat

sorry figures from Apexi PFC

The powerFC get's it's reading from the Coolant Temp Sensor. If the sensor is faulty, then so are your readings. You can buy them from Repco or Autobarn for about $30 and I have replaced dozens due to them being faulty. If you haven't replaced yours yet, chances are it's faulty also. I would start there before running around trying to find an issue that might not be there

    • Oh bugger ! Your right ! Good old hydrogen sulfide. Takes me back to the good old school days ! 
    • I've owned a few scooters over the years, a Vespa PX oil burner was my first scooter, followed by a few others, including a little 50cc BeeWee that I used as a barracks bike, and I've had a blast on all of them, they really are the cheapest for of city/suburb transport around The only issue with scooters in Australia is lots of people look down on them due to their size,  maybe they need a big bike to make up for something else where they are lacking, unlike Europe and Asia where every man an their dog owns one, and now that filtering is legal in NSW, local traffic is never a issue Not to say I haven't owned my share of big cc bikes over the years, but they were for more blasting through the hills or Hwy riding where it needed to sit on Hwy speeds Safety wise, I ride like everyone is always trying to kill me, everyone is running a red, or running stop/give way signs, or generally asleep at the wheel, which most people are duringtheir commute, I also ride really safe, and give myself, and everyone else enough room in case I need to pull some hasty evasive actions, I've done a few rider training days over the years, which has come in handy on more than a few occasions  As for mods, there's nothing really, and yes your right about aftermarket exhaust, all you get is loud and obnoxious noises from them, like every 250-300 cc you hear with a aftermarket muffler, in saying this I did put a rear muffler from a 125 Aprilla on one of my old 125 scooters, it was horrendous and no amount of full face helmet and ear plugs would dampen that noise As for coming from the Harley, and what a overpriced POS that was, I no longer do big rides as my poor old busted joints ache after about 1/2 an hour of riding, long cruises are so much more enjoyable now in a car, so a big bike would be pointless   
    • Oh wow, it's easy to forget how cheap these can be. Probably the cheapest way to travel. Though people in cars here tend to be morons and I would not feel very safe. Were scooters ever big in Australia? It used to be the thing growing up in Europe ~20 years ago. 50/70/125ccm Peugeot or Yamaha and some others. Utterly obnoxious Polini race exhausts. Kick stands that slant as much as possible. So loud. So much noise for really not moving very fast at all. But it felt cool at the time. Not sure where I'm going with this, but there is an aftermarket for mopeds! Though I'd have pictured you more for a Goldwing kind of guy after growing out of the Harley.
    • You need to know I am sorry for this.  
    • As the MX5 isn't apparently "manly" enough, and I need something for runs to the local shops, and also take to my part time job at the salon, basically I can keep the MX5 away from car parks and stuff......like "flying lockers", I was wondering what I could buy to fix this issue LOL, I pick up a new Yamaha 125 Delight this arvo from Trooper Lu, basically a R1 that you can fit a slab of beer on between your feet, also, it was $29400 cheaper than a R1, so actually it's 2 x better than a R1
