how cold does it get? Winter front might help or even some cardboard in front of radiator.

Hey man I have a 99 doing the same thing! I gained some by covering it up. Then pinched off rad hoses. Its my late mothers truck andits neg 10 here ha. It was wrecked about 2 years ago. Dunno if it was ever fixed right

If you have never replaced the thermostat...that is probably the issue. Mine "stuck open" and the temp stopped rising. When I replaced it, it turns out that it wasn't really stuck but all the rubber gaskets were toast and the t-stat was free flowing...I would suggest replacing the t-stat. It is a cheap fix and heat is a good thing.
