Tech Tip: Subaru Fuel Gauge Inconsistency On Forester
The Subaru Techline has received calls about a customer concern that the vehicle’s fuel gauge shows only 3/4-full immediately after filling the vehicle. There are some easy checks that can be performed that will save diagnostic time.
Tech Tip: TPMS Troubleshooting on 2007 Subaru Models
The 2007 Subaru models use a direct detecting-type tire pressure monitoring system (TPMS) that consists of four transmitters and a receiver. If you rotate the tires or install a new sensor, you need the right scan tool or TPMS tool that plugs into the OBD II connection. If the indicator comes on due to low tire pressure, the indicator will turn off when the under-inflated tire is inflated to normal pressure.
Tech Tip: Brake Vibration Diagnostics on Subaru Models
Studies confirm that rarely is it necessary to resurface brake rotors and/or drums on all four wheels when a confirmed brake vibration exists. With proper diagnostics, front or rear brake vibrations can be isolated, eliminating the need to resurface all four rotors and/or rear brake drums.
Z Sport, Part 2: Powering Subaru WRX Engine & Chassis Upgrades
A few months back, I highlighted a project car being built by Z Sport. The car is now back together and running. Charles Damewood, the car’s owner and a principle at Z Sport, has been driving the car to break in the engine, and get an idea of what needs to be sorted out as far as engine management before doing a full on dynamometer test. As soon as fuel mapping and software issues are resolved, we will get full performance testing data and publish a follow up.
Subaru Legacy Outback 2.5L Tech Tip: ABS Motor On, Pedal Descends, But Doesn’t Run
Customer Concern: When you come to a stop, just before completely stopped, the ABS motor kicks on and the pedal goes down, then comes back up. Doesn’t matter what kind of stop. Always does it right before the vehicle is completely stopped. No codes are present.
Tech Tip: Subaru Ignition Coil and High-Tension Cables
When diagnosing a misfire code(s) P0301, P0302 P0303 and/or P0304, there is the possibility that the ignition coil and/or high-tension cables could be the cause.
Z Sport, Part 1: Subaru WRX Performance Brake, Suspension & Engine Mods that Pack a Punch
A project car in the form of a WRX/STI shows that Z Sport in Everett, WA, is all about
Subaru: Coolant Comes Out of Reservoir
If you encounter a vehicle that experiences coolant coming out of the coolant reservoir tank, it may be caused by the radiator cap pressure valve being stuck open by debris sucked up through the reservoir tank hose.
Tech Feature: The Subaru Boxer Engine: A Balance of Power
According to their engineers, these high-powered engines are ideal for all-wheel-drive applications used in Subaru vehicles because they are inherently compact – short and low.
Tech Tip: Subaru Turbocharger Oil Supply Mesh Screen
Turbocharged engines require proper maintenance especially when the vehicle is used under severe driving conditions such as moderate-to-hard acceleration and engine braking on a somewhat regular basis. In any case, it’s recommended that the engine oil and filter be changed every 3,750 miles (6,000 km) or 3-3/4 months.
