Hi all, Today whilst driving on the free way in Melbourne, it was quite warm at about midday, 22-24 degrees approx. Later around 3pm, we had a storm come in and although it was still quite warm, it started to bucket rain and got very very humid. On the freeway my ECUtalk displayed my cars temputer go up to 87. But about 10 minutes later it went back down to 83 and stayed there. On normal driving, it usually fluctuates between 80-84 degrees. Is this normal? Thanks.:zlove:
dudee thats normal as. if ur temps start to get above the 95degree mark then start pannicking lol...but still even then u should usually help the car get cooler not just stop on side of road (obviously depending what has happened) if ur temps get that high try keep the car moving, turn the heater on full blast and hopefulli watch the temps come back down. if they dont then stop and run away from the car
I wouldn't be panicking at 95 degrees. As you can see from the following specs (taken from the "coolong system" tech article) the auxilliary fan doesn't even come on until the temps reach 105 degrees (with A/C off). If the coolant hoses and the rest of the system is in good order then the engine should be able to handle some heat. The Nissan engineers obviously planned for it. Having said that, I certainly would monitor the temps when they get above 95 to make sure they don't go way up, but on a really hot day in traffic I'd expect more than 95, more with the A/C on. FROM THE TECH ARTICLE: The following specs are for the NA fan, and come from the Nissan service manual.Temps are in Celsius: A/C off, coolant temp below 104c = fan off A/C off, coolant temp above 105c = fan on A/C on, vehicle speed < 39kph, coolant below 94c = fan off A/C on, vehicle speed < 39kph, coolant above 95c = fan on A/C on, vehicle speed > 40kph, coolant below 104c = fan off A/C on, vehicle speed > 40kph, coolant above 105c = fan on The TT Z32 has a two speed fan. The following specs are for the TT fan, and also come from the Nissan service manual with temps in Celsius: A/C off, coolant temp below 104c = fan off A/C off, coolant temp above 105c = fan on A/C on, vehicle speed < 39kph, coolant below 89c fan = fan off A/C on, vehicle speed < 39kph, coolant between 90-99c fan = low speed A/C on, vehicle speed < 39kph, coolant above 100c fan = high speed A/C on, vehicle speed > 40 kph, coolant below 104c= fan off A/C on, vehicle speed > 40 kph, coolant above 105c = high speed As you can see, the fan is ECU controlled (A/C, temp & speed sensor input feeds to ECU, output from ECU for fan operation). It is also obvious the fan should not run very often if the cooling system is operating efficiently.
sorry for reviving an old thread, but after doing the conversion and fitting a temp gauge, i'm finding it interesting watching my temp gauge as i'm driving along. took her for a spin yesterday, was a fairly normal, sunny day nothing too hot though. i drove her at 100km/hr for about 40mins in total, occasionally giving it a quick boot for fun. stayed around the 78 deg celsius mark - from what i have read on here i should be pretty stoked with that. just wanted to double check though.
Hey mate. I think that is normal. My digital gauge reading 81-83 degree if boost is 13/14 psi. Freeway run after 30 mins 79 or 80 degree. I am using stock TT radiator with fresh coolant. Hope this helps.
My opinion, if you regularly see over 90 degrees in normal driving (unless it's a stinking hot day), then you may have an area of your cooling system not running properly. The thermostat starts to open at 76.5 degrees Celsius, and is fully open by 84 degrees. So that would be the target temperature range. Obviously with additional heat load like ambient temps, air-conditioner , hill climb, start stop traffic, all these add to the coolant temps. It wouldn't necessarily be abnormal to see 95 degree coolant temps on a hot day, but with ambient temps 22-24 degrees, definitely not. Up to the 84 degrees, no problem.
I remember burning through Northen NSW in the middle of nowhere and it was about 43 degrees according to petrol station temp read out. Road temp would of been even higher, and the engine temp was just fine. The Zed has a wicked cooling system if it's well maintained...
Hmm, this has got me thinking.. Should I get a temp guage installed? Are they hard to install? I have a TWD which I've never seen light up...when does it light up again? Was it over 100 degrees
TWD is calibrated to come on at 95 deg i think, if you've never seen it come on ,,,, all is good with the world Renee .!! Cheers Patrick
temp gauge is easy to install Renee. What amazes me is how quick the stock one gets to the 'normal' level, but how cold the motor still is according to the aftermarket gauge is.
Calibrated for a 95 degree temperature. It should do a test flash every time you key the ignition to ON. If it doesn't, its wired in wrong
Cool, just wanted to confirm when it lights up, so 95 degrees, will have to remember that...yeah it does the test flash everytime I turn the car on.. So what gauges would people recommend?
Water temp, Oil Pressure and Volts if you wanted to, i got one here but never installed it just stuck to water n oil
The stepper motor gauges at www.ozegauge.com.au are quite good I have 2 of these. Smoked, and the temp gauges also have a bright red LED warning of 98 degs C so , like a backup TWD
Hmm, thanks Greg.. I'm contemplating getting a water temperature and vacuum gauge..think they would come in handy.. I'm interested in the A-pillar type housing pods, was just wondering if anyone knows if these are legal? I see UAS sell them..
I'd say laws vary from state to state In QLD, they can't be in the field of view, or be above the steering wheel hight (in the head strike zone)
