The thermostat in a Dodge Grand Caravan is an important piece of the heating and cooling system, as it regulates the amount of coolant going to the system. If the Caravan’s engine takes a long time to heat up, the thermostat is likely stuck open. If the engine is hot but the upper radiator hose […]

The Mercury Grand Marquis is a dependable car with exceptional performance and looks to match. Rarely is major repair required for this car; however, routine maintenance can go a long way toward keeping your Marquis on the road for a very long time. One part of routine maintenance that your Grand Marquis may at some […]

Maintaining proper radiator coolant levels in your 1994 Buick prevents engine overheating. All General Motors vehicles use a specific brand of antifreeze called Dex-Cool. According to General Motors, the use of any other fluid could cause catastrophic radiator and coolant system failure. Dex-Cool is required because its chemical makeup does not damage the metals in […]

Continental makes eight types of four-cylinder L-Head engines and 10 types of six-cylinder L-Head engines, one of which is the F227. These engines are called “L-Head” engines because when you look at the cross section of one, it looks like the letter “L” written upside down. In L-Head engines, all of the valves, valve lifters, […]

The radiator in a 2004 Audi A4 is an aluminum core radiator, which means that it is prone to blockages and internal rust. The plastic exterior is subject to blockages as well, in addition to punctures from road debris. Some repairs, such as small holes in the radiator or rips and tears in radiator hoses […]

Mazda introduced its Multi-Purpose Vehicle (MPV) in 1989 to compete in the mini-van market. It comes with a plastic radiator that has an aluminum core. While the aluminum core can rust, the plastic exterior is vulnerable to breakage, punctures and blockages from road debris. Whether the damage is interior or exterior, it must be repaired […]

A radiator header tank is an integral part of a modern automobile’s cooling system. It has an important role in dealing with the heat generated from a vehicle’s internal combustion engine through the successful continual circulation of coolant. Promoted by Purpose The purpose of a radiator header tank is to provide a place for coolant […]

The cooling system of your Ford Taurus is designed to operate as a sealed system, devoid of excess air. When air becomes trapped in the cooling system it can cause overheating issues. Instead of a typical coolant reservoir, the Taurus uses a pressurized expansion tank that is designed to remove excess air from the system […]

The heater core in your Dodge Dakota, as is the case with any vehicle, is perhaps the most important component in the heating/air conditioning system. The coolant must pass through it in order to generate heat, and a bad core won’t let the coolant pass through. You can usually tell this through coolant leaking into […]

The cost for a mechanic to replace a heater core varies depending upon the type of automobile and the complexity of the repair. There is also considerable variation in the hourly rate charged by mechanics. Promoted by Labor The mechanic should give an estimate of how many hours it will take to replace the heater […]

Overheated vehicle engines need shutting down immediately, often stranding the car in an inconvenient location. Severely overheating an engine creates internal failures, requiring expensive internal repairs or engine replacement. As a result, you should ideally repair the cooling system before major damage occurs. You can often do this by replacing the leaking part. However, the […]

A spark plug is an electrical component of a cylinder head in an internal combustion engine. It generates a spark in the ignition foil in the combustion chamber, creating a gap for the spark to jump across. It also collects the heat that builds up in the combustion chamber and transfers it to the cooling […]

The thermostat on the 1999 Chevrolet Malibu regulates the engine’s temperature. The thermostat has a temperature-sensitive spring that causes the thermostat to open and close as the temperature of the coolant changes. This process keeps the engine block at a safe temperature by allowing the coolant to circulate through the engine when needed. When the […]

The thermostat is part of the heat management system in a vehicle. No coolant goes to the cold engine when it begins operating. The thermostat’s main function is to block the coolant flow to the engine. This allows heat to rise quickly and help bring the engine sooner to its operating temperature. The thermostat does […]
