block heater question?

[payne5757]

Ive started trying out my block heater for the first time since I bought my truck. My question is, when yall use yours after a few hrs of being plugged in does your temp gauge immediately register anything or does it take a couple mins of running before the gauge moves up. It did seem to start easier and the idle was alot quiter than what it sounds like on a cold start but I was under the impression it would be a lil warmer. Btw, I use an outlet timer that turns the heater on for 3hrs before I get in it in the morning.

I plugged mine in the other day and the temp gauge had already moved a little when I started it up.

i normally plug mine in around 9 at night and unplug at 6am and i am normally sitting at the first line on the temp gauge. and my heater is nice and toasty. but whne it gets below lets say-5 or below that its still registers but not as much. and the heater is still warm. know when its gets below like -20 like it does sometimes it doesn't register but its still warm. yours seems to be working just fine. lot of people put them on a timer but i just plug and let go.

The vague instructions say it mounts in a pipe hole near the front of the block, passenger side. I looked all Sat. the only possible place was above the exhaust manifold,can anyone help who has a 94-97 PSD?
