Is This Sort Of Overheat?

[jbjb]

Hi All,

Just bought a 350GT and found the engine temperature gauge is over middle line when the engine's warmed up, is this common in 350GT?

[sheldon2369]

Seems a little hot.

Mine sits around that but on the opposite side. (cooler)

looks a little high too me

Looks a little high, but that is not how Nissan gauges work. Basically all Nissan temp gauges will warm up to their normal running temperature, and sit there until the fluid actually boils (and you have broken something), and only THEN goes off the richter scale hot. Generally they don't move much inbetween.

But you should put a real temp gauge on every Nissan car imho - espeically one with a 95-100 degree warning light. Boiling cars is the 2nd easiest way to blow an engine (next to not enough oil/low oil pressure).

I put an awesome EL overlay over my cluster, and in the process of fitting it put my temp gauge out of scale - mine now sits between the 3rd and 2nd last lines when at operating temp (and already 1/3 way up when cold at start up). That's why I put in a real temp gauge

bleed the system, might need topping up. at that needle position youre probably looking at around 110-112degrees water temp. not the best, but is still operational.

if it doesnt have air in the system, look for a blockage, or check the status of your thermo fans. does it go back down when youre cruising again? if it doesnt, possibly a water pump issue.

Gosh...I and my mech didnt pickup this overheat issue when we do inspection before buying. Now it becomes annoying....

Do you guys think i should go back to Nissan dealer to have diagnosis checks? Or anyone can recommend any reliable mech in Brissy?

Thanks for you guys help~

Mechanic in Brisbane?

Carmen at Brendale, that's where I take my V35.

[jbjb]

Thanks, mate. Brendale might be too far as i live in southside. By the way, does your mechanic have a computer to check up your V35?

Same here and it stays like that almost all the time, regardless of weather.

[jbjb]

Hi Mikhail, so have you ever checked by Nissan or any V35 SERVICE SPECIALISTS before? Or you just leave it as it is?

[zei20l]

or just check the fluid level so that you dont pay someone $180 to top up the radiator......

Did check fluid level is full & top water hose is not too hard to press, fan is only running when a/c is on but even a/c on, the temp is keeping in above middle line...what eles i should check by myself?

[Nightcrawler]

Your thermo fan should come on even when the a/c is off, once the car gets hot enough.

I would be checking for air in your system (which I bet is the cause). Or get a mechanic to install a water temp probe and actually check your water temp to see if your stock gauge is lying/broken.

Just found your question when i was a bit panic, sorry, mate~

I havent flush the coolant yet, but will do soon.

What do you mean by "doesnt have air in the system, look for a blockage" how to check it? I check my fan only runs when a/c on but it doesnt go back to normal temp even with fan (a/c on) on or when i am cruising again.

Water pump issue? What other procedure that i can check whether it is water pum failure? Pls advise, thanks~

Thanks, Andrew. How can you check air in your system?

Unscrew the little plastic bleed screw in the left hand side at the rear o fthe engine. If you look along the water piping you will see it - it is black plastic and has an X in it to unscrew it with a phillips-head screwdriver.

[zei20l]

if you can, park the car on a down slope so that bleed point is highest in the system. it helps..........

I am leaving mine as is as I am pretty certain its normal. I think I saw a similar thread on here that said the same thing. I had mine serviced and no problems were found. Also my needle is just below the middle, yours is above middle.

If you have access to someone with a datascan tool, get them to check the coolant temperature with it, if it is around 85-90 deg C, then I wouldn't worry about it. Especiallly if it doesn't seem to go up and down when driving hard, or climbing hills

I wrote a proper bleed procedure somewhere on G35, just search my name.

Also get a radiator cap with temp control gauge on it, you can go check yourself.
