Coolant System Repair
Although gasoline engines have improved a lot, they are still not very efficient at turning chemical energy into mechanical power. Most of the energy in the gasoline is converted into heat, and it is the job of the cooling system to take care of that heat. Ironically, the engine in your car runs best at a fairly high temperature. When the engine is cold, components wear out faster, and the engine is less efficient and emits more pollution. So one important job of the cooling system is to allow the engine to heat up as quickly as possible, and then to keep the engine at a constant temperature.

Coolant is the fluid that absorbs heat from the engine and then dissipates it through the radiator. It is also dissipated through the heat exchanger in the passenger compartment when you crank your heat in the winter. Coolant, which is commonly called antifreeze, is a mixture of ethylene or propylene glycol and water, usually in a 50/50 ratio.
Because it is operating in a hot, hostile environment, coolant will break down over time. Most importantly, the coolant’s rust inhibitors get used up, leaving the small cooling passages in your engine and radiator vulnerable to corrosion. Even with these rust inhibitors, some corrosion will inevitably take place, contaminating the coolant with debris. This can cause damage to the coolant system which will require repair, or just a flush of the old coolant if caught in time.
Servicing the coolant involves draining and/or flushing your car’s cooling system and then replacing the old coolant with fresh coolant. This removes dirt and rust particles that can clog up the cooling system and cause problems in winter and summer.
Pet Owners Beware!
Antifreeze has a sweet aroma and taste, which pets find particularly appealing. As little as a half teaspoon of the stuff can kill an average-size cat, and eight ounces will do in a 75-pound dog. There’s no substance that you can add to antifreeze to make it less appealing to animals, but antifreeze made with propylene glycol instead of the usual ethylene glycol is about a third as toxic. Propylene glycol is sold under the brand names Sierra, Prestone Low Tox and Texaco PG.
In time, these bits of rust will also clog the tiny passages within the radiator and heater, causing your engine to overheat. When an engine overheats, the result is a bonus yacht payment to your mechanic that someone else should be making.
If you check your coolant level when the engine is cold, the coolant should be at or above the “minimum” or “fill” line on the transparent refill container. If you check your coolant level when the engine is hot, the coolant should be at or just below the “max” line.
Check your owner’s manual to see if your car uses “long-life” coolant. For the first 100,000 miles, it is necessary to check the coolant level simply to be sure you’re not leaking or burning coolant.
Disappearance of coolant could be caused by either an external or internal leak, the latter being more expensive. Either one should be addressed quickly, since running low or out of coolant can lead to catastrophic engine failure and many boat payments to your mechanic.
