Hi All . Whats the temprature a 1275 should run at in degrees, im running a temp guage other than the factory one so id like to know whats normal an whats hot as the factory guage always sits on 3/4 wether its hot or cold

The correct thermostat is an 82 degree type, though apparently the later one, like your in your 1275 LS, were fitted with 88 degree type. I've never actually found one of these factory fitted and I do actually prefer the 82 degee unit. I see that you've a capillary gauge, but with the standard electric one, it will sit about half way with the 82 degree t'stat.

On a capillary gauge, with the 82 degree t'stat, they generally sit around the 78 to 84 degree mark.

I would guess that if the factory gauge is sitting around the 3/4 mark, you've got an 88 degree t'stat.

Hope that is some help.

Thanx Mr Mowog

Yep, I'd agree with that one. I put an 88º thermostat in my car to get my oil hotter quicker, and the standard Smiths gauge reads between half (steady cruising) and three-quarters (stop-start).

So thats ok then I just have a thing about my engines running any thing past half, just doesnt sit well with me

This is just my view on actual engine temperatures for street stuff.

If you live in a colder area, 88 degrees is good, because i) it helps get the oil temp up and ii) it get the heater going to warm your toes.

Otherwise for the rest of Oz, 82 degrees is OK. This usually put the factory temp gauge about half way.

Others might fill you in better tan me on this, but max power happens at about 72 to 78 degrees.

At the end of the day (and again this is just my view) the actual temperature is not too importatnt, but is is important that the temperature is stable, that is is doesn't keep going up and down as you drive. When parts heat and cool, they move (cylinder heat on block for example).

Just my view.

I know what you mean, I still have a oh-sh1t reaction whenever I glance at the temperature gauge, but I'll learn eventually

Like GT Mowog says, the 88º thermo is good in colder climates, especially when if, like me your daily drive is only 10km or so. Over such a short distance the oil doesn't get hot and so never burns off the combustion gases which dissolve in it.

Since using the 88º item my oil is actually cleaner for longer

Maximum power would be at about 120° but it is not good for a long and healthy engine life.

Thanx Guys

i have also fitted an aftermarket temp guage and it read way higher than the actual temp 110 when it was actually at 76 when im running a 71*c thermostat.i bought an thermometer adaptor for a automotive multimeter which is just a wire type from jayca and fitted it to the top rad hose nearest to the thermostat and left it there permanantly .if you ever get worried all you have to do is plug it to your multimeter nd that should give you the most acurate reading.adaptor cost me $9.

Thanx Encho, Great idea mate

Try and buy one of these. Just point it and press the button and it tels you the tempareture of the object you point it at.
