Fuel Injection Keeps Getting Better for MADISON HEIGHTS Motorists

MADISON HEIGHTS residents know that engines burn fuel to operate. Fuel is pumped from your fuel tank to your engine where it is squirted—or injected—into your engine's cylinders. This is the function of the fuel injectors.There are two ways to inject fuel into an engine. Fuel needs air to burn, so in the first method, fuel is injected into a port and allowed to mix with airand before it is drawn into the cylinders. In the second method, fuel is injected directly into the cylinders and mixes with air after it enters the engine.Direct injection engines burn fuel more efficiently than conventional engines. Some models can deliver the power of a V8 with the economy of a V6.For example, in one family of engines, the conventional version (a V6) delivers about 250 horsepower. The direct injection version delivers over 300 horsepower and gets about the same . The turbocharged version delivers 350 horsepower.Why the big difference in power? D ... read more

Automotive Tips from Interstate Auto Care: Air Conditioning – Common Problem

Your auto air conditioning system cools and conditions the air in your passenger compartment when you are driving around MADISON HEIGHTS. It also removes moisture from the air to keep your windows from fogging up.A common A/C problem for MADISON HEIGHTS drivers that visit Interstate Auto Care is contaminated refrigerant (the gas that cools the air). The inside of the A/C hoses deteriorates over time and tiny fragments of rubber clog passages. This makes the system less efficient and overworks various components.Leaks can develop at seals and gaskets and may reduce the amount of refrigerant, causing the system to work too hard to compensate. Dirty components can have the same consequences.Ask your Interstate Auto Care service advisor for an air conditioning system inspection to make sure everything is up to spec.Interstate Auto Care526 E 14 MILE RDMADISON HEIGHTS, MI 48071248-307-1200

MADISON HEIGHTS Drivers: Is It Time to Replace Your PCV Valve?

MADISON HEIGHTS Drivers: Is It Time to Replace Your PCV Valve?

The crankcase is the lower part of the engine where the crankshaft is housed and where the engine oil lives. The crankshaft is connected to the pistons that power the engine. When you are diving around MADISON HEIGHTS, fuel is burned in your vehicle engine, it pushes the pistons down and the crankshaft rotates and sends power to the transmission. Some of the explosive gases from combustion squeeze past the pistons and down into the crankcase.Now this gas is about 70% unburned fuel. If it were allowed to remain in the crankcase, it would contaminate the oil and quickly turn it to sludge. Sludge is like Vaseline and clogs passages in the engine, leading to damage. Also, the pressure build up would blow out seals and gaskets. So in the old days, there was just a hose that vented the crankcase out into the air. Obviously, not good for our air quality in MADISON HEIGHTS, MI.Enter the PCV valve. It's a small, one-way valve that lets out the gases from the crankcase and routes them ... read more

Engine Hydration for MADISON HEIGHTS Drivers: Role of Your Water Pump

The cooling system in an engine has five components: the radiator, the radiator cap, the hoses, the thermostat and the water pump. The water is literally the heart of the system. Just as your own heart keeps your blood circulating through your body, the water pump keeps coolant circulating through your engine.The water pump is driven by a belt, chain or gear and only operates while the engine is running. It has a limited life span and sooner or later will have to be replaced. You can check your owner's manual to find out how long your water pump should last. Some can fail at only 40,000 miles (64,000 kilometers), but almost all of them fail by 100,000 miles (160,000 kilometers).Water pumps don't gradually wear out; they fail. In other words, they're either working or they're not. A failed water pump has to be replaced.Water pumps can fail in two ways: they can spring a leak or their bearings fail. Leaks can come from a cracked pump but usually develop at the gasket whe ... read more

Below 45 Degrees in MADISON HEIGHTS: Consider Winter Tires

Remember snow tires? They were basically just regular tires with big, knobby lugs to get them through deep snow. They were loud and rode hard, and MADISON HEIGHTS drivers couldn't wait to get them off the car. Then along came television advertisements for “all-season” radials. MI drivers ran out and bought some and we thought we were done with snow tires forever.Tires have come a long way since then. Modern winter tires sold in the MADISON HEIGHTS area are much better designed for the wide range of conditions that come with MI winter weather. They are made with a rubber compound that helps them stay flexible in cold weather. Regular tires become hard and stiff at MADISON HEIGHTS temperatures below 45°F (7° C) which reduces their traction. That's a concern in winter, especially with snowy or wet conditions. But it also means that MADISON HEIGHTS drivers are better off with winter tires in cold weather even when it's dry.The tread design on winter tires has been impr ... read more
