Thermostats open and close with changes in engine temperature, and sometimes become stuck. If stuck open, the engine never warms up properly and there is little or no heat from the heater. A stuck-open thermostat can also be a cause of poor fuel economy.
Stuck closed, a failed thermostat can cause engine overheating because the coolant
Extreme heat is still gripping much of the United States and summer long-distance travel is still on many people’s agenda. In order to make it through the rest of this record breaking hot summer make sure to have your service professional check your engine cooling system belts and hoses.
The cooling system hoses and belts can deteriorate over a period of time. The
Many vehicles now have electric cooling fans that do not operate until necessary, when the engine coolant temperature climbs above a certain point.
The heater core is located inside the passenger compartment of the vehicle, quite often very deeply buried inside or under the instrument panel, or behind some other type of interior trim panel. Some SUVs and vans have two heater cores, a front and a rear.
A radiator has 2 tanks, one containing the inlet and one containing the outlet. These tanks, which can be at the top and bottom or sides, are usually made of aluminum, brass, copper, or plastic (most newer vehicles use the plastic type).
This particular cabin air filter came from a Volvo class 8 truck and it hadn’t been changed for three years! It was retired in favor of a replacement. We wanted to share this photo with you to show you how cabin air filters do their job
The water pump is the heart of the cooling system. It circulates the coolant through the engine, radiator and heater core. These days, certain vehicles (like some SUVs, vans and most hybrids) often have more than one water pump, and the auxiliary pumps are usually run by electric motors and controlled by a computer.
The purpose of desiccant in a mobile air conditioning system is to absorb and hold
moisture. Moisture in a system (above an acceptable level) can lead to corrosion and
degradation of the lubricant.
Some odor treatments are merely feeble attempts to cover up odor. They are doomed to fail. Almost all odor treatment products fail to provide a long-term residual effect that can reduce the reoccurrence of odor. Here is a brief description of the performance capabilities of various odor treatments by product type.
/C system odors typically result from uncontrolled growth of bacteria and other microorganisms in the evaporator part. Nasty little beasts like aspergillus, cladesporium and penicillium grow on cooling coils and other areas. How do these beasts get there?
They are naturally present in outdoor air and are drawn into the system through the evaporator during system operation.
