temperature range

Yes the half way point is the one to watch > I find just under half on the gauge the engine is up to temp , hard driving will go just over especially if oil is not full. In my winter here at 20degC and below the gauge drops to two thirds of half half because I have a FMIC and when the AC is on temp will drop slightly. Some info here >

when i am with A/C i cannot drop it to low ....meanwhile , i have a second gauge for temperature (defi gauge) ,temp goes to 108C, meanwhile the stock gauge stills at the center ...I have dataloged water temp too , an yes it is exactly what indicates the defi gauge...
i think my car has a headgasket prolem

I hope not but driving with high temp is no good either way.
> Would check the thermostat opens should be at 82degC for stock type.
> Also check Water pump , if top and bottom radiator hoses get hot it is circulating.
> And are both Radiator fans functioning.
> You could check for water loss etc . but I have been advised by posts here that the water sniff test is best way to check for headgasket trouble.

just a summary of the seo:
-block verified
-head skimed
-beck harnley head gasket
-arp head bolt (new)
-new water pump
-without thermostat ( i have fitted a new , no change)
-water sensor fitted on the top of the radiator (defi system)
-timing verified
-flat piston all forged (come back to low compression to verify )
-5e block
-all hose changed
-radiator cleaned
---->stills hot ...on cruise i have 97-101 degre monitored on the ultimate & on the defi (only 2 degre less but very high)
--->i have done a test without thermostat and the problem stills
when i accelerate and turbo begins to create boost, i saw temp rising ...
the problem is that the toyota gauge is lying a lot , if i have not fitted the defi sensors i will never see the problem...it is only when after fitting my 5e with the silly mechanic that i saw the problem , temp was rising and if i stop the engine and go down the engine is cooling ...

for the sake of comparison, here are my stats, if they are of any help..
:: engine is mostly stock (at least on the cooling bit of things)
:: ambient day-time temps are about 29 deg C
:: running green-stuff coolant and i often get about 96 deg C when in slow traffic
:: running 15w-40 oil and that gets to about 88 deg C
:: when on open road doing 50mph averages, i get 88 coolant temp and about 80 oil temp
ps: my defi coolant temp sensor taps adjacent from the thermo housing so i believe i'm getting close-to-accurate readings..
i know it's obvious at this point but i'm presuming you have checked that your thermostat is operating normally..?

could the difference be due to where your sensor is located?
is your sensor fitted a similar place to dark-knight?
which temp sensor is your emanage using to record temps?---stock or defi?
is the car overheating or losing any coolant?

1/my sensor for the defi is fitted to the top of the radiator hose
2/i datalog it on the ultimate on the stock sensor (only 2degre C of difference ) both sensors show me that it is hot ...
3/i do not lose water but if i insist to go on moutain road , water comes out the botle coolant
is my paseo radiator undersised ???

I've seen 115c on my defi water temp gauge - fitted in the upper rad hose, and the stock gauge didn't even twitch from the middle position.

that is right but if you datalog it you will see on teh stock sensor a value close to 115c due to the fact that the TOYOTA gauge lies

does your radiator look/sized like any of those? - go to bottom of page

no, my radiator is finner than the tercel radiator...
