Engine Maintenance: Timing Belt Replacement on Lexus GS 300s
Recommended replacement intervals for timing belts are all over the map these days. Mileage and time suggestions can vary widely, so examine accessory belts and factor in the use of the car and its maintenance history. In this article, we’ll discuss timing belt replacement on a 2001 Lexus GS 300 model with the 2JZ-GE engine.
Proper Piston Replacement
While the “Fast and the Furious” crowd may have lost interest in the sport compact market, interest in the cars hasn’t dropped off completely.
Tech Feature: Servicing Ford’s 3.0L Engine
The 3.0L Duratec V6 was introduced in 1996 to replace the aging 3.8L V6 in the Ford Taurus and Mercury Sable. Unlike its conventional pushrod predecessor, the 3.0L V6 has dual overhead cams, four valves per cylinder and an aluminum block with cast-iron cylinder liners.
Carley’s Corner: Changing Automotive Technology Makes ‘Right To Repair’ Act a Must for Independent Repair Shops To Survive
The past few years have seen rapid change in automotive technology. More and more hybrid models are being introduced, with nearly 1.5 million already being sold to date. Direct gasoline fuel injection is replacing port fuel injection on more and more engines. Many late-model engines are also equipped with variable valve timing (VVT) to improve
Gearing Up for Timing Belt and Chain Work
Timing belts are a maintenance item on engines that have them, but what about timing chains? On most overhead cam engines that use a timing chain to turn the cams, there’s usually some type of chain tensioner or adjuster to keep the chain tight and to compensate for stretch as the chain ages. But on pushrod V6 and V8 engines, there is no chain tensioner to compensate for chain stretch. Consequently, after tens of thousand of miles, the chain loosens up, starts to make noise as it rattles against the front cover, and causes cam timing to retard. At this point the timing chain needs to be replaced.
Down the Road: Advances in Engine Technology
Two engine technologies that have been around for years are generating plenty of interest these days as the automakers look to create better fuel efficiency, without sacrificing power — direct injection for gasoline engines and turbocharging. Direct injection for gasoline engines is where fuel is injected right into the combustion chamber of each cylinder, as
GM Timing Belt & Chain Service
Some overhead cam engines in General Motors vehicles use timing belts to drive the cam (the 2.0L for example), some use chains (2.3L Quad Four, Cadillac’s Northstar dual overhead cam 4.6L V8, the Aurora Northstar 4.0L V8 and Chevy’s Vortec 4200 inline six), and some use a combination of both (Chevrolet’s 3.4L V6).
