Tech Tip: Clogged Oil Line Leads To Chrysler/Dodge Turbocharger Failure
Extreme temperatures cause the oil circulating through the turbocharger oil feed line to burn. The coked oil buildup restricts oil flow, which leads to turbocharger failure. The oil line may appear fine externally.
Tech Tip: Hydro-Boost Tips And Hints
Hydro-boost brake systems are self-bleeding if there is no other problem in the system. Use this initial bleeding procedure whenever replacing or servicing any component in a hydro-boost system. Normal driving conditions will remove air that remains trapped within the system when components are properly installed and there are no flow restrictions in the system. Always refer to the vehicle service manual for specific installation and testing procedures on import and domestic vehicles.
GM Belt Tensioner May Cause Supercharger Failure
When the belt tensioner starts to fail, belt tension increases dramatically. This tension shows up as side-loading in the supercharger rear bearing.
Tech Tip: 4WD Transfer Case Motor Typical Failures And Prevention
This Tech Tip applies to Chevy/GMC, Ford, Mazda and Isuzu 4-wheel-drive vehicles equipped with transfer case motors. Most units fail because of water or mud intrusion. Carefully inspect the motor boot or protective coverings. Be sure the connector seals can keep water and debris out. Check the wiring harness and connector. Replace or repair wiring as necessary. After installation, periodically select 4-wheel-drive mode to ensure operation when needed.

Ford Tech Tip: Cackling Powerstroke Injector
Some Ford diesel vehicles with the 7.3L engine may experience a misfire or “cackle.” The injectors in the 7.3L diesel run off of the high-pressure engine oil pump.The #8 injector is the farthest away from the oil pump, causing a filling problem, which may result in a misfire. Ford replaced the #8 injector in some vehicles as needed with a different injector to solve the problem.
Tech Tip: Bent or Binding Mounting Pins May Cause Slider-Style Caliper Problems on Brakes
Carefully inspect all brake mounting surfaces and hardware for corrosion, wear or misalignment.
Tech Tip: Every MAF Sensor Needs a Breath of Fresh Air
Sensor replacement is critical to engine efficiency because a dirty MAF sensor will not respond as fast to air flow changes as a clean sensor.
Tech Tip: Intermittent ABS Operation Caused by Cracked Sensor Ring
Rust can develop between the axle and the ABS speed sensor ring. The rust acts like a wedge and causes the ring to crack, creating a false or erratic signal that results in intermittent ABS operation.
Tech Tip: Nissan Quest is Experiencing Brake Lock-Up
Contaminated brake fluid may have blocked the ABS modulator valves or the “dampener valve.” The dampener valve is a component that is screwed into one of the outlet ports of the master cylinder. The brake line for the left-front and right-rear brakes come out of this part. Another possibility is that the ABS system component failure is causing brake pressure not to be released.
