Turbocharger Repair – Shaft Play

Turbocharger Tips

Turbocharger shaft play is a term that applies to the actual shaft which runs between the intake and exhaust housings of a turbo. There are many types of turbochargers that each will have acceptable shaft play. Most turbo units are floating bearing turbos which means that the oil pressure is required to stabilize the…

Known Issue: Toyota Prius AC Oil Contamination

Proper Knowledge of Air-Conditioning Systems is Vital! Hybrid A/C systems may be classified as service-critical from more than just one perspective. Service-critical in the sense of higher demands to the required know-how and skills than for any other auto air-conditioning system. Working on vehicles with high voltage drive systems also requires know-how on how these…

HOW TO REPAIR COOLING FAN

A/C Tips

The internal combustion engine used in modern day vehicles is based around the idea of a gas being ignited and then the force from that explosion being harnessed to create movement. This process creates a large amount of heat which needs to be dispersed to prevent engine components from being affected by it. The cooling…

Car AC system diagram: compressor, evaporator, drier, expansion valve, condenser.

AC System Oil Levels

Oil is as important as the refrigerant in an AC system. The refrigerant is subjected to extreme pressure changes which generates a lot of heat, in addition to the heat produced by the AC parts themselves. The oil absorbs this heat and keeps the AC components lubricated. The amount of oil should neither be lesser…
