Answers: If this is a latest problem, it could be low coolant, core/hose damage, or gunk build up from impossible anti-freeze.
First, check your coolant to see if it has outmoded oil contained by it, a VERY serious problem! If it has whitish, gunky build-up, you may enjoy a bad gasket it the engine. If the coolant looks OK, it may be an outmoded water pump. Both can be checked duly cheaply at a regular automotive shop. Most oil progress places can do it too. Old hoses can cause this too, check them by squeezing the larger hose down hoses. If they don't rebound after anyone squeezed, or if they are brittle and break, you found a problem. A disentigrating hose can clog your hot water flow. Crappy anti-freeze can gunk up, and the system may stipulation to be flushed. If you've never had the coolant system flushed surrounded by ten years of ownership, it needs it.
If this happen every winter, it may just be your winter driving conduct. Trucks tend to have larger grills than cars, and they go and get more air flow underneath the hood. This keeps your engine from heat up quickly. Some northern truck drivers hold zippered grill covers on their trucks. They adjust the air flow until the engine temp stays where on earth they want it. (Assuming you drive in a cold climate) Semi trucks own air brakes, and sea freezing in those lines can be chancy.
One tip, turn the heat horizontal all the instrument up, but put the fan at minimum. People that rust their vehicle to melt snow/ice/frost save the engine cool by running the fan too glorious, then consent to out the tiny amount of heat when they start the doors to get surrounded by and out. Keeping the fan low help the engine build heat faster, instead of using the oven to cool the engine by blasting the coil with cold nouns!
In Germany, people would put a plastic water/oil decanter in front of the radiator merely behind the grill, it blocked the cold nouns from cooling the radiator too much, and they had spare coolant/oil.
Plastic/cardboard deflectors be common too, but it get down to -40 below farenhite at times, it could cause a day-time problem of over heat if your daytime temps get up to 60.
sounds approaching your thermostat is sticking open, i'd swing it first, they are cheap...
