jjdugen Posted September 21, 2015 Posted September 21, 2015 Hi all. Don't know whether tech or general but... How long does it take to the Z get warm enough to drop engine revs to normal idling? Mine seems to take up to 10 mins before the temp gauge starts to climb and the revs drop back from circa 2K to just below 1K. On a recent run at steady motorway speeds, early morning so a bit chilly, the temp gauge hardly moved, had me leaping out to check coolant level! Is this OK? I know its a big lump with a big rad but on most of my local drives I hardly need to touch the accelerator! Cheers Quote
Ekona Posted September 21, 2015 Posted September 21, 2015 10 mins seems excessive to get any coolant temp in, but then that depends on how cold it is I guess. I'd expect a short drive of a few miles to at least see the needle moving. Quote
catman Posted September 21, 2015 Posted September 21, 2015 Could be a faulty thermostat. That sounds far too long to warm up at this time of year. Tim Quote
Rock_Steady Posted September 21, 2015 Posted September 21, 2015 Mine's warmed up after a couple minutes down the road, 10 minutes sounds a bit excessive to me.. Quote
ZMANALEX Posted September 21, 2015 Posted September 21, 2015 Possibly thermostat stuck open. Is your heater working okay ? Quote
jjdugen Posted September 21, 2015 Author Posted September 21, 2015 Hi all Once the gauge moves, the heater is nice and toasty. I did suspect the thermostat myself, just needed a bit of confirmation. It may just be that I drive it like a pussy until warmed... Anyway, where is the thermo, how easy to get too? Cheers Quote

thedon Posted September 21, 2015 Posted September 21, 2015 Have you changed anything recently, or cleaned the throttle body? If the idle has always been high try the idle air volume reset. Do it once the car is warmed up and all switches (fan especially) are off. Mine idles at around 1500 cold and within 30 seconds drops to maybe 1200, then 800 when warm. If you have Air Con switched on it raises the idle a bit... Quote
jjdugen Posted September 21, 2015 Author Posted September 21, 2015 I take it you mean the throttle pedal dance? Sounds like fun, I'll give that a go tomorrow. Cheers Quote
thedon Posted September 21, 2015 Posted September 21, 2015 It's one of several pedal dances - it's a hoot, especially when you don't time it j-u-s-t right... Best use a watch with a second hand. Good luck Quote
jjdugen Posted September 22, 2015 Author Posted September 22, 2015 Did the dance, even used my 'ring stopwatch, no flashing light. But... It now starts up at 1.3K RPM and drops within a minute or two down to 800 RPM. Temp comes up much quicker...... Mystified! Cheers Quote
thedon Posted September 22, 2015 Posted September 22, 2015 (edited) Result The joys of the inner workings of the ECU eh? I did it about 7 times, all with the CEL light flashing as it should, before it actually seemed to 'take'. Edited September 22, 2015 by thedon Quote
Quinster Posted September 23, 2015 Posted September 23, 2015 Read the original post and am I correct in thinking you're flicking the accelerator to turn the choke off? Quote
jjdugen Posted September 23, 2015 Author Posted September 23, 2015 Tel me about flicking the accelerator........... Cheers Quote
a2orry Posted September 23, 2015 Posted September 23, 2015 Think you need to go back to the start of the thread 10 mins is way to long for warm up and it will get longer the colder the weather gets faulty thermostat gets my vote pedal dances will reset ecu this has no effect on the thermostat Quote
catman Posted September 24, 2015 Posted September 24, 2015 I agree. The warm up time is really only dependant on the thermostat. Tim Quote
