BLOCK HEATER

[99BEIGEPOWERSTROKE]

I was wondering is there a way to test to make sure the block heater is working correctly before it gets any colder here in Ohio?
Thanks

get a digital meter and take aresistance reading I believe it will be around 10 ohms, or could take an amperage reading, it should draw approximately 9amps

Not to sound dumb but where would you take the measurement from?

[jamstoyz]

ohms at the cord end or amp reading at the power source. you should be able to tell if its working just by the temp gauge. your heat should be somewhat warm too in the morning. sometimes you can hear it click on and make like a hissing sound when first plugged in.

plug it in tonight and listen to it.....you should hear it start to work after a few seconds.

When it gets down to around 25ish here,I plug mine in and the temp needle moves a little when I hit the switch.Might could do a test run and see if it is warming the coolant(cold engine of course)

Do you take the reading when its plugged on or what? Not sure what you mean?

Yes take the readings with it plugged in. I would just plug it in for about an hour and see if your coolant is warm!

Just take cap off and see if its warm or just turn key on and see if temp gauge moves?

Plug it in for two hours and see if the temp gauge goes up a little when you turn the key on.
