optimum engine operating temp

[ae86 slide]

my enginge rarely reaches 80c, usually sits just above 60c, i read that generally optimum operating temp is between 80c to 100c?
am i doin my engine harm driving hard below 80c?

[SPEEDCORE]

Can I ask what kind of temp gauge you are running..... and if it is mechanical or electric...

Doesn't sound right!

[crazy86]

Oil or Water temp?

[Monster]

I'm guessing you mean water temp... well yes the opt temp is about 80deg 60 sounds awfully low. Are you running an oil cooler? Have you checked your thermostat?

[Hyuga]

yea my 20v always sits at around a quater on the ae86 dash temp guage, I was wonder why the water temp is so cold, it doesn't even have got an electric fan installed yet, but then last week I drove my car to the city and there was traffic everywhere and my car overheated... I think it is my thermostat but my thermostat is still at the back of the head that seems impossible to remove it. http://www.ae86drivingclub.com.au/forums/emoticons/dry.gif

not exactly sure but i think electrical (drops to 0 wen ignition is off), and it is in farenhieght, and yeah thermostate might be a bit of a mission to get to

Oil or Water temp?[/b]
water

Are you running an oil cooler?[/b]
no

[crazy86]

The thermostat should be in the top outlet of the water pump.

ITs running at 60 Farenhiet? that equals 15 degrees Celcius, which is kinda cold.
It should be running at about 80 deg C, which equals 175 deg F

Edit:

Sorry dude, missed that. http://www.ae86drivingclub.com.au/forums/emoticons/wink.gif

[ae86 slide]

no i said 60 c in the first quote, already converted it. so running at about 140f

mine was running cold for a while, checked the thermostat...it was non-existant! chucked one in and its all good http://www.ae86drivingclub.com.au/forums/emoticons/smile.gif

read the post first ya tool he said 60c, stop trying to display your false intelligence.
and maybe try posting some usefull information [/b][/quote]
And how many usefull posts have you posted, Mr Im a cool Dori slut. You dont know me from shit, so STFU.

Do you use red coolant or green coolant?
What percentage mixture do you run?

Cheers

green coolant, prob bout 40% coolant, prob a bit much hey?

[sic86]

Toyota actually recommend to use a red coolant in all Toyota vehicles. 40% isn't that much You should use between 33% - 60%

Cheers

[Sprinterboy]

Who sells red coolant?

[Monster]

Thread modified by me.
Try to keep calm peeps!

Nulon do red coolant. It is good

***CAUTION***

* You cannot use red coolant with copper core radiators

* If you do change from red to green, make sure you flush every drop of the old stuff out, if they mix, it can solidify and or rust out bits and peices very very quickly.

[SPEEDCORE]

Can I ask why? Sounds like a load of shit to me since it is a dye afterall.

[b1gb3n]

my water temp is all over the place. optimum temp in the city around 80-90+.

70 on freeway during day

55-60 on freeway at night.



i have oil cooler. dont think its thermostat, dont see/hear fan running unless temp is high.


quite a few people seem to have this prob on 20v in 86. i think maybe engine will be warmer with splash guards on. the guards at front below radiator/engine. my old car seemed to run cooler without it.


also im thinking of using hotter spark plugs to see how it goes

What the hell is it with people at the moment???
Can you ask why What? Why you shouldn't use it with copper/brass radiators? Because the chemical make up of it is different to the green stuff.
Why you shouldn't mix them? See above

Nulon Australia (http://www.nulon.com.au/)

Check out the cooling section

You know SPEEDCORE, not everyone talks shit on here, most people do know what they are talking about http://www.ae86drivingclub.com.au/forums/emoticons/angry.gif
------------------------------------------------------------

b1gb3n: try putting masking tape over the oil cooler when driving at night, engine temp levels should be kept up in the 75-95 deg mark

[SPEEDCORE]

Nice to see you edit your post to have a dig at me specifically.

Did I personally say you talked shit? Stop assuming.. its no good for your stress levels.

My post was in reference to that actual colouring dyes posing no such properties that would interact.... and to use your words "rust bits out".

I think you forgot that I actually contributed to this thread in the early stages as opposed to slagging people off like AE86DriftSlUt did.

[ToySprinta]

Check out the latest Street Machine, they got an interesting article on coolant additives.
They reckon that, unless you're car is sitting for a weekend at perisher, that antifreeze is useless in Australia.
The boiling point is acutually controlled by the pressure in the cooling system.
The main constituant of anti-freeze, glycol, actually doesn't absorb and dissapate heat as well as water, as well as being more viscous.

So, i'm going to give just a rust inhibitor additive a go, like water wetter or something.

[mosqiton]

Thats actuall very true ToySprinta, I use probably about 10% coolant just to get some colour for the overflow bottle. Especially when you run Aluminium radiators the coolant actually corrodes alloy. Been doing it for years with no probs. As an answer to the orignal post 80-100 degrees celcius is "optimal" but there is no adverse affect running slightly lower such as 70 degrees. It also depends on where you fit your temp sensor as well. The exit pipe on the top hose is uaually the hottest place as thats where the coolant comes out of the engine. There is a few degrees difference from the back of the head and the top hose.
