Timing Chain or Belt: How Can an Engineering Change Affect Your Shop?

Like it or not, modern technology dictates how the modern independent import repair shop does business. Case in point, the first “rubber” timing belt I saw was in 1968 on a domestic-manufactured single overhead camshaft, six-cylinder engine. Given our experience, we had quite a laugh over the prospect of these gear-toothed “rubber” timing belts lasting

Idler Pulley Failure

The majority of the Subarus towed into his shop with timing belt failure can often be traced to an idler pulley failure that resulted in the belt coming off, says Bob Dowie, who advises to replace the pulleys if you have any doubt about their condition, notice grease coming out of them, or if there is roughness or noise when they are spun.

Subaru 2.5L Stretch Belt Replacement

Subaru stretch belts can last 100,000 miles or more. On a worn belt, the cracks or damage to the backing of the belt will not be evident to the naked eye. This is why an inspection method that measures groove depth is recommended – you simply cannot go by mileage recommendations alone.

Mazda Tech Tip: P1443, Engine Idles Rough, Replaced Idle Air Control Valve

The car might be more than 20 years old, but that doesn’t mean you don’t want it to run smoothly. In this case, the component related to the code was not the culprit. Follow along with this Real Fix to learn about the cause.

Mazda Pressure Breather Hose Frozen, DTC P0451

Some vehicles may experience a MIL on with only OTC P0451 stored in the memory. This is caused by water entering and freezing in the atmosphere breather hose of the fuel tank pressure (FTP) sensor. For Mazda3s, this happens when the vehicle is washed in a high-pressure car wash. For the CX-7, this happens when the vehicle is driven on a wet road. To correct the problem, a modified breather hose has been adopted.

Engine Design: A Changing Diagnostic Approach

Modern propulsion technology requires high-speed data processing systems. For that reason, our relearning process actually began when CAN bus electronic systems were introduced by Mercedes-Benz circa 1990.

Lexus: Flex Lock-Up Shudder

Some 2011 model year GS 350 and 2011-’12 model year IS 350/350C vehicles may exhibit an intermittent flex lock-up shudder when lightly accelerating between 25-50 mph (40-80 km/h). Follow the procedure in this bulletin to address this condition.

Honda K-Series Engine Bearing Identification, Installation

Honda uses a specific bearing selection process for both rod and main bearings. It includes using a chart along with the identified parts included in the engine being rebuilt. Connecting rod bearing selection uses four possible rod journal codes to match with four big end bore codes that are color coded based upon size.

Tech Tip: Mercedes-Benz Cylinder Head Cover Leak

Field inspections of suspected cylinder head cover oil leaks have revealed that unnecessary resealing is being performed when the cylinder head cover is not the root cause of the leak. In cases of customer complaints of oil leakage, it is essential to determine the actual source. A proper remedy should be applied to avoid repeat repairs and unnecessary shop visits.

The Engine Thermostat: Understanding Electronically Assisted Thermostats

The engine thermostat plays an important role in increasing engine combustion efficiency and reducing emissions. But today’s electrically assisted (also called “map-controlled”) thermostats provide broader and faster operation than the traditional engine thermostat.
