If the inside compartment heater in your Sports Utility S.U.V., truck or car is running cold and not outputting suitable quantities of heat you may have been told to “replace the Volvo vocom thermostat “.Typically this really is the next thing in the diagnostics of an auto interior heater running “cold “.
What are the overall steps in the diagnosis and diagnostics of none, low or inadequate heat from a standard engine coolant fired interior compartment auto heater? First the amount of antifreeze coolant ( or this case heating) liquid is checked to make sure that is adequate to operate through the core of the heater within your passenger compartments to “throw” out enough heated air to defrost your front windshield for good safe driving and keep you and your passengers comfy warm. The question is if your radiator (or specifically your engine block) thermostat is no longer working properly or needs and upgrade to a winter temp model how will you start selecting a replacement.?
When replacement of the engine thermostat is essential it is vital to select a thermostat of the proper and adequate pressure range. Otherwise it’s false economy and you will soon be left with warmer but nevertheless lukewarm heat output from your heater. If its cool or cold now, it only going to get worse as winter moves towards colder and more predictably frigid temperatures of January. Baby its cold on the market in northern Alberta and BC Canada come cold winter nights and evening highway driving. Generally experienced mechanics and factory trained technicians and dealership service techs recommend that you utilize “pellet” type thermostats in pressurized auto radiator cooling systems. Virtually all vehicles we encounter now squeeze into that category. The less common “bellows “type thermostatic units will simply work in non-pressurized automotive cooling systems.

In the great majority of cases in the cars and trucks we drive the radiators employ ethylene glycol or an ethylene glycol/ water mixture. That’s perfectly fine. Yet in some more non-conventional or even exotic engine and driving setups an alcohol based coolant might be filling the rad and coolant hoses of your motoring system. In these specific cases the thermostat will need to have a lowered raring for safety of approx 160 degrees Fahrenheit ( 71 degrees C) which can be much less than the conventional glycol based thermostat. This is completed for reasons of safety.
One last point not so much for simple auto owners and drivers who’ve been told it may be recommended to restore this module to “get heat out of their heater” and simply want the task done at their local garage or car or truck dealership, is for many who link to tinker and mess around with auto mechanics and diagnostics. At the least the thermostat in vehicles today still utilizes old technology. They’re not some Vocom 88890300 sophisticated piece of electronics that need factory specific tools and procedures.
Yet while the back yard mechanic may yet tinker with rads and thermostats ensure it is a basic tenet of automobile and in this radiator cooling system diagnosis and diagnostics never leave the thermostat out of a motor as an old mechanics “trick” to cool engine overheating. The thermostat in your cars engine is vital use more than one as required. If the thermostat is taken out — at best come wintertime again the indegent auto owner will be freezing to death within their vehicle along side unsafe frosted windows come next winter season. Be warm and comfy in your car or truck, driving safely down the road with frost free clear windows because of a checked or new replacement thermostat in your cooling and heating systems.
