Funny thing happened today ... last night temps were in the mid to upper 40's Went out to start the truck .. started fine .. let the truck idle for a min went to shift into drive ... it dies ... Started it back up and let it idle for 5-10 min and it went into drive fine . My question ... what gauge do I need to watch in order to get it up to temp , oil , water , trans ect ? And what is the proper temp to get it to before putting it in drive . I have 2 battery blankets and trans heater on the way . And I also have the heater block . Didnt know I needed the this soon ? I can already tell this truck will be cold blooded .
