Modern Cooling System Design: It’s Not About Temperature; It’s About Powertrain
Reading engineering papers tends to be a boring exercise, but they do give technicians a new perspective on how a common automotive cooling system could actually be improved.
Serpentine Belt Drive Alignment And Wear
Belt misalignment can be caused by any of the accessory pulleys or might be the result of improper belt installation.
HFO-1234yf: What’s Required
Unless you’ve been living under a rock, you might have heard about the new regulations and requirements for R-1234yf usage. Not sure? Well, it’s time you crawled out from under that rock and get ready for some of these new regulations that will affect you and your profession.
Six Tools For Servicing Serpentine Belts
Servicing the serpentine belt on some vehicles is a tough task. Without the right tools it is almost impossible. Here are six tools to make your next belt replacement more productive.
Oxygen Sensor And Catalyst Efficiency
The catalyst efficiency monitor verifies the catalytic converter is operating at a high enough efficiency rating to keep exhaust emissions within the predetermined values. The PCM compares the signals from the upstream and downstream oxygen sensors to determine the state of the converter. These “tests” are called the readiness monitors.
The Turbo Comeback: The Small Engine, Big Performance Trend
Turbochargers are great for adding power to any gas or diesel-powered engine, but especially for small displacement engines. They were all the rage back in the 1980s when BMW, Mitsubishi, Toyota and Volkswagen all offered turbo options on a variety of engines. Over the years, turbos have come and gone, but recently, they are making
Oil Pump Diagnostics: Rebuild Or Replace?
Considering how important oil pressure is for all of these reasons, why would anyone take a chance on reusing a high-mileage oil pump when rebuilding an engine?
Belt Tensioner Inspection & Replacement Tips
Most late-model engines have serpentine belt drives for the engine-driven accessories, and most people know that belts are a maintenance item that eventually has to be replaced. However, many people 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.
Component Connection: Belt Wear Diagnostics
Serpentine belts may last up to 100,000 miles before they need to be replaced. If a belt fails sooner, you need to be a detective and investigate why it failed.
CAN Communications Diagnostics: Honda Case Study
This Honda was towed in with a loss of power, check engine light on and a P1607 code indicating an internal PCM failure.
