how long should i leave my block heater plugged in for?

[jesilvas]

All night if you want. But the general consensus is three hours before you plan to start it up.

Also,

thanks, i was just wondering.

how warm should the block or coolant be after being plugged in all night. Would you be able to see the temp guage off min. position?

[jesilvas]

Depends on the temp. If it's around 40 and mine's in all night I can just BARELY see it up a notch. If it's around 30 it'll start rising pretty quick after the water pumps starts running.

You will notice it more in the sound of the injectors and how easy/hard it starts when cold.

When it is 0-12* out even when pluged in it sounds a bit groggy for a few seconds. If it is 12-32* when plugged in it sounds good!

My ECT is between 110*F and 95*F depending on ambiant night temps...EOT 95*F to 85*F...much easier on start-up and I can kick the heater on right away.

I leave mine plugged in all night, warms up real quick...
