Water Temp

[R-SPEC]

with aftermarket gauges, what should it normally read?

need to work out wether my sensor's farked...

thanks

[joeleo87]

well i thought half way was good?

if u need to know buy a new sensor and cut it into ya top radiator hose.

[Dan_J]

or just tap da sensor wire off the ecu temp sensor to after market guage

I assume your asking for temp? If you have a Power FC + commander you can compare to the stock one.

Usually around 70-80degrees which is under halfway on the factory gauge @70degrees celcius...

A lot of other people run 80-90 degrees which is probably half way or past half way on the standard gauge, which I hardly ever look at so I'm just guessing here

Hi there

160~180 deg F is about ballpark for lite use. (160~180)-32*(5/9) for deg C................. (degC*9/5)+32= Deg F or yoostabe, back in the bad old days.

You need a known good sensor to isolate source of error.

Find/steal/borrow known good replacement sensor & place (whilst still connected to your wiring harness, ignition on~ might need extension lead knockup) in cup of ice cubes floating in water, 60/40 mix, for 0~4 degC check of gauge, place in cup of boiling water for 95~100deg C. or there abouts. If ya want to get serious place a thermometer in reference liquid.

Alternatively you could plug your display into a mate's motor/temp sensor arrangement & verify your gauges.

Cheers GW

stock thermostat should be 89C

convert that to degree's F if you have an american guage.

My defi reads, 85 or so on regular driving and just above 90 on hard driving. Lcimate will play a big factor as well and also what coolant you're running, I run Texaco extended life and I am thinking about switching to Red Line Water Wetter.

Stock thermostat is 76.5C.

Normal Operating temperature in the region of 82C.

Boiling point of most systems, 110-115C.

Stock dash temp. gauge is useless, half way (few mm either side) ranges from ~60C - ~95C, you won't notice it moving until you've already hit 100C.

Just below the top of the gauge for me is 104C (only seen that high once after a few big burnouts).

PowerFC

Normal Crusing about no more than 90 degrees, last Sunday on that f-off heatwave in Sydney with the A/C going I got 98 degrees with some light spirited driving.

[Haines]

85 - 95 for me up here in sunny north qld

where its hot all the time

[bubba]

Never see over 95 on the street and that's usually on a really hot day stuck in traffic.

[Dose Pipe Sutututu]

My old 180 was the best, she'll be sitting on 95 most days, that's with a twin core GT-R radiator and 3 thermos... good ol' RB in a S13 chasis.. LOL.... overheat Queen!

Yeah mines about the same Pedro, microtech hand controller displays about 85-90. I've seen it over 90 a couple of times when giving it a bit during the day.

Gotta love our heat lol.

Man i've got it good, runs about 75-80 depending on weather and up to 85 with hard driving in brisbane in summer.

I don't have air con though so that helps get some more air into the radiator.

Interesting I am removing my aircon condenser and receiver/dryer soon and putting a pair of thermos where they used to be along with some splitters/guides

the standard ecu and powerfc keep the timing a little retarded and richen it up a little until water temp is 80deg or higher

half way on the stock guage should be 80deg

i Dont think the water wetter is such a good idea in an rb. It does not stop rusting of the block and eats away the water jackets over time...... Cost me a whole Fuc&in engine!!!

[r33cruiser]

normal driving pfc reads 78-81C. thats with stock thermostat, and your basic coolant.

Use it as an additive on the street, running it pure with just water would only be recommended for track use.

interesting. myne usually sits at 75-77 and only ever goes higher if thrashing it on a hot day (highest its ever hit is 81). got a pfc and i doubt it would have been over 80 when it was tuned, might explain a few things
