Was wandering what can I do to this 12 v to get max heat in winter months and faster warmups , my temp gage climbed to 75 c or 165 f max after 25 miles yesterday , outside temp was -18 c

Try a winter front, heard of some people using cardboard with a small hole cut in center.

Every year when the average daily high temp drops to the 60s, I pull the fan. Then if we get really cold weather, I can block off the radiator. Use cardboard, for a temp block or winter front.

The good thing about cardboard is if you start out with a piece large enough to totally cover the radaitor, it's easy to trim a bit if more air flow is needed should things start getting too warm.

Just be sure to slip the blocking material between the intercooler and rad.

Also, I run a 195deg. thermostat, in reality, it's the thermostat that determines how warm things stay.

Good luck, RR

One big reason I don't like '98s is because the heater **** doesn't have a recirculate position like the earlier years. The only position on the new trucks that doesn't bring in cold outside air is max A/C - who the heck wants to run the A/C when it's 10 below zero?

Be careful with cardboard. You need to cover 100% of the coolers or have any airflow go right though the center of the fan.
Putting in a strip of cardboard that leaves openings on the top or sides causes the fan blades to flex every time they go though the uneven air flow. A blade will eventual break off over time from this possibly causing major damage. This only happens with metal fan blades, plastic ones can handle the repeated flexing.

Plugging in and using the recirc position is all I really need to be toasty right away.

Bill is right, if using cardboard (with the fan) it's best to cut a hole thats centered on the fan to avoid fan blade flex. My comments were predicated on pulling the fan.
