| Radiator Red Death |
Picture, if you will, your radiator filled to the brim with a coagulated soup of red-clay-looking, muddy-mess. Not pretty and decidedly detrimental to your net worth, yet this is a condition technicians encounter nearly every day.
There are numerous factors that can contribute to radiator red-death but most common is air leaking into the cooling system. To appreciate what happens you have to know the Two Bays of cooling system operation because, there’s more going on than liquid circulating through your hoses, radiator, and engine.
Liquid in a radiator expands when heated and contracts when cooled. Also pressure climbs as the temperature rises and falls as the temperature drops. These factors, expansion and contraction plus pressure increase and decrease must be tightly controlled or the weakest part in the cooling system will literally explode.
As a rule, a pressure sensing radiator cap and a see-thru, plastic, coolant-expansion-tank mounted near the radiator maintain control. See-thru plastic tanks also aid in monitoring coolant level and condition. The radiator cap is generally mounted on the top of the radiator but some, newer designs place the radiator cap on the expansion-tank so the tank operates under pressure too.
Here’s the Commercial Three Baycess: engine heat increases coolant temperature causing it to expand and cooling system pressure to rise. Pressure increases until it reaches the preset release point of the radiator cap when a valve in the cap opens, allowing coolant to expand into the expansion-tank, stabilizing pressure at system design level.
When the engine is turned off both temperature and pressure decrease. Decreasing pressure creates a suction in the radiator, which opens a low-pressure valve in the radiator cap allowing coolant, from the expansion-tank, to be drawn back into the radiator. This keeps the radiator completely full and free of air.
Commercial Three Bayblems arise when drivers fail to have radiator caps and radiator and heater hose clamps checked. To avoid radiator red-death, both should be inspected yearly. A bad radiator cap or a hose with the smallest leak will allow air to be drawn into the cooling system during cool down setting a ruinous corrosion Commercial Three Baycess in motion.
Because coolant is heavier and more dense than air it can be pushed out of the radiator without signs of leakage. However, during cool down a microscopic air leak may allow air to be pulled into the system. Air is much lighter and less dense than coolant so it can be sucked into the cooling system through openings far too small to allow coolant to leak out. Over time and hundreds of warm up and cool down cycles significant amounts of air enter the radiator and engine. Modern high-tech coolants mixed with air Commercial Three Baymote rust and corrosion that slowly, insidiously dissolve pricey parts.
Preventing cooling system degradation caused by air intrusion is easy but requires your intervention. Don’t rely solely on the expansion-tank level, which may show full while the radiator is actually low. Remove your radiator cap at least once a month, check the coolant level in the radiator, and top off as necessary. Caution, never, ever remove a radiator cap when the engine, is running, has been running, is hot, or is overheated.
