Hello and thank you for reading my post.

I wanted to ask a question of some importance now because I live in Alaska and the current temp is 10 F and dropping to about zero at night.

I have a 1996 Ford f-150 straight 6 truck...

Recently in the last few weeks I notice the heating dropping in performance and then no heat. A few times it seemed to come back on with maybe 20 percent of its total normal heat then the next day nothing.

One day a few days ago the heat came up full. Now though nothing comes from the heat.

I also notice in the last few days that the engine temp goes almost all the way up then will drop some then rise, drop then rise etc... This drop and rise does not seem to matter if it truck is moving or not.

Any ideas on what this might be?

PLEASE HELP BECAUSE IT GETS TO BE ABOUT -50 F to -55 F at times in December and January and rests normally about -20 F the rest of the time in Winter.

Thanks again for reading this post

Sincerely,

Kevin <<FREEZING>> in Alaska
