The thermostat is responsible for keeping your engine at normal operating temperature, and the hot engine coolant is what warms the air from your heater. If your car requires cardboard to block the airflow through the radiator in an effort to force it to overheat, then you have a thermostat issue.
Why do trucks cover their grill in the winter?
In the winter months, drivers would cover a portion of the grill to limit the amount of frigid air flowing through the radiator to help keep the engine temperature high enough to provide sufficient heat to the cab.
Why do diesels have grill covers?
Its to keep the heat in when idling. Stop your truck on a cold day and just idle and watch your temperature go down. Its the reason big trucks have high idle also. Another the big trucks also is because they have a line that bypasses the thermostat and goes straight to the radiator.
What does a winter grill cover do?
The cold environment lends to a reduced risk of overheating. Preventing air flow through the radiator grill helps reduce drag coefficient on some vehicles, which helps improve fuel economy.
What is a Winterfront on a truck?
Like a scarf protecting your neck from the cold, a Winterfront Grille Cover protects your truck. This cold weather essential reduces and redirects frigid cold air from flowing into your truck’s grille while still allowing adequate air to flow to all areas of the cooling system.
Do grill covers prevent rust?
A grill cover will help keep your grill looking good for years to come. You should cover your grill after every use once it has cooled down. While some worry that a grill cover will encourage rusting, this is a myth.

Why do cars have grills?

At the front of the vehicle is an opening that allows the air to move into the engine compartment. The air helps to cool the radiator and the engine, so nothing overheats. To cover that hole, manufacturers will install an accessory known as the car grille.
Do winter fronts work?
A: In extreme cold weather, winter fronts do help the vehicle warm up faster. … A better method to reduce airflow in the engine compartment is to cover the grille and the opening below the bumper with a winter front. This still allows some air through the radiator but blocks most of the cold air.
What is a radiator shutter?
Open shutters allow air to flow through the radiator and into the engine compartment to promote cooling. When cooling air is not needed, the shutters close, rerouting air around the vehicle to reduce aerodynamic drag and fuel consumption.
