Tech Tip: Installing Reman Engines and Transmissions
With new car sales down, people are keeping their vehicles longer and racking up more miles on their engines. That means there’s a growing opportunity to install a remanufactured engine in a customer’s vehicle if their original engine or transmission has reached the end of the road. Most engines will go quite a few miles with proper maintenance. But if the owner scrimps on regular fluid, oil and filter changes, neglects the coolant, never changes the spark plugs, or ignores little problems, it may lead to premature engine failure.

Tech Tip: Diagnosing a Faulty Water Pump
The water pump is one of those parts that no engine can run long without. If the water pump shaft seal leaks, the cooling system will lose coolant and the engine will overheat. That means a breakdown – and a sale of a replacement water pump. The water pump circulates coolant between the engine and radiator to keep the engine from running too hot. Almost a third of the heat produced by combustion ends up as waste heat absorbed by the ….
Tech Tip: Inspecting the Spring-Loaded Automatic Belt Tensioner
The automatic tensioner has a coil spring inside that applies just the right amount of force against the belt to keep it tight. The tensioner also provides a little "give" so it can absorb and cushion shock loads on the belt that occur when the A/C compressor clutch cycles on and off. What’s more, the tensioner automatically compensates for wear and keeps the belt under constant tension.
The Circle of (Engine) Life: The Important Role Water Pumps Play in Engine Preservation…Restoring the Engine to Precise OE Tolerances
Amazingly, up to one-third of the heat energy produced inside an engine’s combustion chambers ends up as waste heat that goes into the block. This heat must be eliminated, otherwise the engine will overheat and self-destruct. The water pump keeps coolant circulating between the engine and radiator to get rid of the heat. The pump
Tech Tip: Maintaining Belt Tension is Critical
Most late-model engines have serpentine belt drives for the engine-driven accessories. And most people know that belts are a maintenance item and eventually have to be replaced. But many don’t know the spring-loaded automatic tensioner that keeps a serpentine belt tight is also a wear item. Consequently, the automatic tensioner may also have to be replaced when the time comes to change the belt.
Chevy AVEO Timing Belt Service
As a rule, General Motors uses timing chains rather than timing belts on most of its engines. Timing chains are long-lived and reliable, and do not have a recommended replacement interval. Not so with timing belts. One GM engine that does use a rubber timing belt is the 1.6L E-TECH II engine in the 2004
Autodata Publications Inc. Introduces 2007 Edition Spanish Timing Belt Manual

and below the intake manifold. When this unit fails, it tends to look like the head gaskets are blown. The oil mixes with the coolant and so on, leading to catastrophic engine bearing failure. Saab recommends flushing the cooling system with Shout, a cleaning agent found in many stores. Saab also recommends changing the timing
