QUESTION: cooling system
Hi there.
My 11 years old car recently started to experience cooling system problems. It does not overheat. The problem is, once it gets at nominal temperature, there 'seems' to be too much pressure building up in the system. As a result, the hoses are leaking. I have tightened the metal clamps (holding the hoses on the other parts) as much as possible but it is not good enough. One amateur mechanic told me there may be too much obstruction in the system due to limestone accumulation in the radiator and other locations. Is this possible? Furthermore, he told be that a quick fix for that is to put 2 spoonful of sodium bicarbonate (aka baking soda) in the coolant tank, run the engine for a while and then flush the system. Does that make sense? Is it safe? To get rid of limestone, wouldn't a product such as CLR (rust/limestone remover) do better? Or is there a product available specifically for this kind of cooling system maintenance? Thanks |

Could be they've hardened and thus not sealing well. Replace the radiator cap. That is the device that controls the amount of pressure in the system. Replace the coolant and add distilled water at normal maintenance intervals. If the car is not overheating, then mineral accumulation, if any, is not yet a problem. |
