When I plugged in my warmer last night it made a strange sound..

Almsot like a fan came on!!

Did it again a few minutes ago as well... Its only about 45* here, but I have to get up early and its such a pain with the EGR blocker to drive around town to class with the Engine Temp. @ 58* bright and early and in a rush!!!

Should it make a strange sound??? I will check again in about 30 minutes to see if ti continues!!!

Just the water heating up. Noise is normal.

I have not read manual on the block heater, but how long can it be plugged in at night. Can I plug in at 10-11 at night and unplug at 7am?

There is no harm done by leaving it plugged in as long as you like. However; there is no additional benefit gained by leaving it plugged in longer than 4 hours. The block will reach it's max temp by then and additional time just adds to your electric bill.

thanks, i dont want to wake at 3-4 am to plug in and i dont want to do any harm. the dealer mentioned only a couple hours. but on my suburban i left in all night and never had a problem.

only problem of all night is the power draw, 1500 watts IIRC (6-10cents/hr) , so could get expensive if done every day.

Just go to wal-mart and get a timer...

cost $10.00, set it to turn on about 3:00, and off at 8:00
