normal operating water temperature

Post by jcrcleeman »

I've fitted an engine water temperature gauge and need to adjust the scale to suit the normal operating temperature of the water, but what is it for a 1098 engine? 82°C?

I can test the sender in a mug of hot water so it's relatively easy to adjust, I just need a figure to aim for.

Thanks in anticipation!

85 to 90 C rings a bell, but can’t remember where that came from. What temperature thermostat do you have? Mine is an 85 and the engine runs at about 88 (assuming my gauge is accurate of course).

Surely you want a thermometer in your pan of water and set it to read the temperature as accurately as possible in the range 75 to 110.

Under pressure you can get water above 100 without it becoming steam.

"Normal" temperature depends on quite a few things.

Ignition timing and mixture can alter it as can badges on the grille and the fan you have.

And of course the Great British weather. Sunburned my head the other week and hit with hail stones yesterday :D

When I see mine going up to 80 I switch the electric fan on, but on the open road I can often switch it back off again as it drops until I am in traffic.

The main use of the thermostat is to make sure the engine gets warm fairly quickly so its useful to know what it should be then you know if its working.

As you can see individual degrees are not showm, merely a "range" from cold to hot which you can set/adjust.

My thermostat is 88°C.

Sean, I'll have a go at setting the gauge between the limits of 75 to 110°C and try and get 88 somewhere near the centre of the scale.

My setting/testing kit does include a thermometer (it followed me into the garage from the kitchen! :-)

Ah I understand now. :oops:

Yes go for the 88 ish straight up.

Hopefully if it has 40 degree ish range then if 90 is straight up, 70 would be 20 below and 110 20 above.

Once you start using it you will soon see where it normally runs.

Another handy kitchen tip is you can wash cylinder heads etc. in the dishwasher. As long as you don’t have a partner of course.
