Should I Change the Thermostat?

Unless an engine overheats or fails to reach normal operating temperature after being driven for several miles, the thermostat that regulates the flow of coolant is probably working properly. Thermostats generally last for years — even for the lifetime of a vehicle — so why bother changing it?

Indeed, if it appears to be working, there probably isn’t need for a new thermostat. However, if you’re having other cooling system maintenance performed, such as replacing the coolant and/or the radiator hoses on a vehicle that’s been in service for several years, it could be a good idea to replace the thermostat at the same time for peace of mind. That’s particularly true if the upper radiator hose is being removed, as that’s where many thermostats are located.

Aside from this type of preventive maintenance, a thermostat doesn’t need to be replaced unless it stops opening and closing when it’s supposed to. If it sticks in the closed position, that traps coolant in the engine so that it overheats. If it sticks in the open position, the coolant will constantly circulate through the engine and radiator, which can prevent the engine from reaching full operating temperature (and full efficiency) and reduce heat output from the climate system.

Among the signs that a thermostat isn’t working are an engine that overheats or runs hotter than usual, or a cabin heater that fails to produce sufficient warm air. A faulty thermostat may also trigger the check engine light. Because these symptoms can be caused by other problems, the entire cooling system should be inspected by a pro before deciding to replace the thermostat.

Not getting enough heat in the interior is mainly a comfort issue, but overheating can cause serious engine damage and shouldn’t be ignored. Most vehicles have a temperature gauge that gives a constant reading of the cooling system temperature, ranging from “C” to “H” or blue to red. In modern cars, the needle or bar graph will come to rest dead center, or just a notch or so toward the cold side, when the engine has reached optimum temperature. Cars with this gauge might also have a warning light for when the engine is running hotter than normal.

An increasing number of cars do away with the gauge and have a high-temperature warning light, either alone or supplemented by a separate indicator — typically a blue icon of a thermometer sitting in water — that comes on when you start a cold engine and stays lit until it reaches the proper operating temperature. If this indicator stays illuminated, there’s a good chance the thermostat has stuck open.

A gauge can give a driver an early heads-up that something is wrong, but a warning light might not come on until the engine is so hot it needs to be turned off immediately to prevent damage.

Does the Brand of Gas You Use Matter?

Many car owners have wondered to themselves on occasion “Does the Brand of Gas I Use Matter?”

Maintenance_139We’re here to tell you that the answer is yes. The reason being that some brands contain more detergent additives that can prevent carbon deposits from forming inside your engine.

These are the so-called Top Tier brands that use considerably more detergent additives than is required by the EPA. Several vehicle manufacturers recommend using Top Tier gas so they and their dealers don’t receive complaints from owners about poor performance or fuel economy caused by carbon deposits, fouled fuel injectors or other issues.

Most major oil companies have adopted the voluntary Top Tier standards for detergent additives, including Shell, ExxonMobil, BP, Chevron, Phillips 66, Texaco and Valero, among others.

The vehicle manufacturers claim that using other brands of gas over time can allow carbon deposits to form in combustion chambers, which can cause engine knock or pinging (premature fuel ignition), and on intake valves, which can impede valve operation.

This doesn’t mean you should never use anything except Top Tier gas, although using Top Tier gas as often as is practical and economically feasible is a helpful. If you choose to use other types of gas in your vehicle, periodically adding a fuel system cleaner should do the trick.

Which Body Style is Right For You?

Forget the number of models available, the number of body styles alone can be overwhelming: coupes, sedans, station wagons, crossovers, SUVs. How do you decide what you need?


Coupe/Convertible: If you want a car that makes a statement about you, coupes and convertibles are typically the most expressive designs, but restricted access to the back seat (if the car you are considering even has one) seriously limits their practicality.

Sedan: If there are kids in the picture or in the near-future plan, four doors are a likely requirement. Even if children are small enough to ride comfortably in the back seat of a coupe with any regularity, consider the difficulty of constantly climbing into and out of the back seat to tend to a child before committing to just two doors.

Hatchback: If you add another door—bringing the total to five—you’re looking at hatchbacks and station wagons, which offer SUV-like space without the dynamic and fuel-economy compromises of heavier vehicles. As manufacturers get increasingly creative and design ever more stylish hatchbacks—their roofs are sleeker than wagons’—the market is warming to the segment.


SUV/Crossover: Jack up the ground clearance of a hatchback or station wagon, and you have a crossover or an SUV. Do you need that ground clearance? Probably not. When was the last time your road didn’t get regularly plowed or cleared? Sure, it happens—most often to those in the northern part of the country, and that’s a few times a winter—but the fuel-economy penalty of opting for a taller and heavier vehicle is something that affects you every time you start the car.

Those who tow regularly already know they need something with that capability. But if you need a truck only to tow a few times a year, perhaps renting in those instances is a better alternative to living year round with the fuel-economy penalties of a truck.

Minivan: Those with large families—or dreams of such—often resist the practicality of the van, but if you routinely haul five or more people, there is no vehicle short of a school bus that will better accommodate six, seven, or eight passengers. A jumbo SUV like a Chevrolet Suburban or Ford Expedition EL has more cargo space, but passengers will find greater comfort in a minivan.
