not actually running a little hot (faulty temp sender) - zx_volcane - 25-06-2012
The temp on the zx has always sat just a tad above 90.
After fitting the t25 it was getting a bit hotter.
So changed out the radiator which was fubared, and the thermostat, coolant and fan temp sender for good luck.
Still sits just above 90 but doesn't get much hotter now on a run.
The black zx sits just below 90 and might rise a bit when pushed on a run (k14 @25psi + fuel)
Can it be a gauge /temp sender issue? Or is it just running hot.
Don't think its the headgasket as I've done silly miles on it and its stayed pretty consistently hot over 30k.
Pointers please

90 is quite hot running for a derv. Mine runs just over 70
Sure its not just because of the hotter weather

Since I've had it, it has always run a bit hot, all year round - stays pretty consistent though.

Mine runs at 80. But when I push it get to 90. It's gets there faster now after tuning you the turbo and other tuning last weekend.
I have a nissen rad.

Maybe get a seperate water temp gauge? I'd be worried if mine sat just over 90 all the time.

I swear mine's generally running cooler with a big blower on boost.

Maybe the thermostat a little sticky?
Might be worth a new one for piece of mind

90 does seem a little hot the fan should be kicking in round that temp.
RE: running a little hot - zx_volcane - 26-06-2012
The fans dont kick in - and I've replaced the thermostat and fan temp sender in the rad - and if you short it the fans do come in.
Separate gauge might eb the answer, but I can swap the temp senders from each car for now.

Ok, having read this and knowing that mind pretty much constantly sits at 80* and that every XUD I know of sits around 80* and given what you have done already.............are you sure the needle on the gauge is in the right place? as the stats are 83* so it shouldn't get much hotter than that really ever so 90* would be strange!
Also with the fans not cutting in even though they work and the fan sensor is new I would also say points to the gauge being wrong as the coolant isn't getting hot enough to trip the sensor IMO
Maybe get a digital thermostat and see what temp the header tank is at compared to the gauge? it won't be totally accurate but it will give you a better idea
RE: running a little hot - zx_volcane - 26-06-2012
Good news
Swapped the sensor and temp reading normal
So overreading temp sender - or given that its just a thermistor maybe someone put the wrong one in at some point.
Hoo-bloody-ray

Which sensor is it that you've swapped as mine also has the same symptoms? Tried solving it with a nissens rad new thermostat and a good coolant mix but still no luck it shoots up to 90-95 when booting it but under normal driving it hovers between 80-90 with the heaters on but if I leave them off it just keeps climbing ? Any ideas
RE: not actually running a little hot (faulty temp sender) - zx_volcane - 29-08-2012
Think it was the blue temp sender in the top of the thermostat
Can work it out which it is by unplugging it and seeing if your temp gauge cuts out
