How Do Radiators Fail and When Should They Be Changed?

How Do Radiators Fail and When Should They Be Changed?

Your radiator is responsible for removing heat from your engines coolant to help keep your engine cool. A leak free cooling system and a properly functioning radiator is key to the reliability and longevity of your vehicle. When engines get hot or “over heat” internal engine damage can occur. In years past radiators were constructed from brass or aluminum fins and soldered on to brass or aluminum tanks. Today most modern vehicles have aluminum fins which are crimped on to plastic tanks. The most common areas for failure on modern radiators is either where the plastic tank seals to the aluminum fins, or the plastic tank itself. Cooling systems are also subject to pressure, most cooling systems operate between 13 and 16 psi. Plastic tanks heat and cool at a different rate than the aluminum core. Over time the heating and pressure created from the heat, and the pressure relief from cooling wear the plastic on the tanks of the radiator. We find that over time the black plastic ... read more

Slow coolant leaks. A small leak can turn into a big problem

Slow coolant leaks. A small leak can turn into a big problem

Today while inspecting a Rav4 we found a slow coolant leak on the upper radiator hose at a Tee. Coolant can leakfromyour enginecoolingsystemat a rapid rate and you will see liquid dripping from under your vehicle, or see a puddle under the vehicle. Many coolant leaks start as slow leaks. You can see a crusty residue around water pump seals, radiator tank seams, hose connections and anywhere else where coolant is contained. It is far better to catch a coolant leak before it starts dripping or becomes a major leak. Depending on your vehicle your cooling system can be under anywhere from 13 to 18or morepsi of pressure while at operating temperature. A small leak can turn into a large leak in an instant sometimes causing the vehicle to lose a significant amount of coolant in a very short period of time. When a vehicle isranwhile low on coolant it can overheat causing engine damage.Routine checks of your cooling system can help prevent problems before they occur. At Tim’s Quality Car ... read more
