Modern engine technology combined with the poor quality of most gasolines are wreaking havoc on the induction systems and intake components of our engines. Most engines in vehicles built after 2005 are equipped with Gasoline Direct Injection (GDI) fuel systems. GDI injects the fuel directly into the combustion chambers. Unlike intake port injected engines (1980's to 2005ish) which can clean the intake port and valves when good fuel and additives are used, the GDI systems leave these components untouched and contaminated with carbon deposits. They literally strangle the throat of your engine by restricting air flow into the combustion chamber. These deposits cause a myriad of problems from poor idle quality, sluggish performance, lower gas mileage, and all the way to engine damage if left unchecked.
> In January, we will be offering a state of the art cleaning process using the ATS 3C Intelligent Induction Cleaner. Unlike "spray cans" or even "pressurized bottle" cleaning methods, this machine accurately dispenses cleaning fluids based on the engine we are cleaning. Using a three chemical process, The computer controlled system safely cleans by alternating between two chemical treatments and finishes with a rinse agent. This procedure, combined with the patented chemicals, will clean the induction system, intake valves, and ports along with the carbon deposits in the combustion chamber without causing damage to the engine or the catalytic converters. While this method is more expensive than spraying a can of cleaner down the engine intake. Using this cleaning method we can guarantee a safe and reliable induction system cleaning every time. Even though this system was specifically designed for GDI engines, it works superbly on most gasoline vehicle engines from carbureted, to every type of fuel injection system. Note: there are a few European engines that cannot be cleaned due to their intake manifold configurations. Give us a call, we can give your car's engine a breathe of fresh air.

Our vehicles contain miles of wiring. When built, this wiring is armored against chafing by a plastic conduit, and anchored in position with plastic clips. I use the terms,
" armored" and "anchored" loosely, as these plastic pieces become brittle and ineffective when exposed to the high temperatures under the hood. When servicing a vehicle, care must be taken when working around wiring harnesses as it it very easy to break brittle anchors. When an anchor breaks, the harness must be remounted in it's proper position, we use aircraft grade cable ties.
These photos depict a repair of a very nasty electrical gremlin. This vehicle came into our shop after many expensive parts were replaced in an attempt to fix a transmission shifting problem. A broken anchor allowed this wiring harness to lay down on top of the engine. The plastic conduit was no protection against the insistent rubbing caused by the engine vibration and the valve cover wore through the wiring. This caused a large voltage drop in the wiring circuit as only one strand of the multi-strand wire was left to flow electricity.

The Braking system on your vehicle is a Hydro-Mechanical system, this means it uses mechanical components activated hydraulically. In a Disc Brake system, fluid under pressure from the foot operated master cylinder forces pistons in the brake Caliper to extend, this squeezes brake pads against the spinning rotors. This slows your vehicle in the same way as dragging your feet to stop a bicycle. Most brake Calipers are of the sliding design. This type of caliper has one or two pistons on one side and applies pressure to the opposing pad by sliding on it's mounts, pinching the rotor between the pads. This movement of the caliper requires clean and lubricated slides and mounting surfaces. When these areas become corroded or rusted they cause the caliper to bind. Bound calipers wear the pads unevenly shortening brake life. More importantly as in the case of the caliper mounts shown here, a bound caliper causes pulling, or unintended turning of the vehicle when the brakes are applied.
As part of all brake jobs we inspect, clean and lubricate all caliper sliding components.

Serpentine Belt Squeal!!
Belt noise can be caused by a variety factors, from a simple worn out belt, worn pulleys and bearings, or to the most problematic, misalignment.
There are 2 types of belt misalignment, angular and parallel. Angular misalignment can be caused by a worn out tensioner, broken accessory (a/c, alternator ) mount or severely worn out pulley bearings. These defects allow a pulley to sit crooked or angled in relation to all the other pulleys. Parallel misalignment can be caused by a improperly installed accessory pulley or a defective harmonic balancer. In this alignment issue the pulleys are not angled, but their groves don't line up, forcing the very wide serpentine belt to snake back in forth.
A harmonic balancer is attached over the outboard end of the crank shaft. The balancer contains a rubber mounted inertia ring which absorbs torsional ( twisting ) vibrations produced as each cylinder fires and accelerates the crank shaft. The inertia ring can double as the belt pulley and has grooves to drive the serpentine belt. Over time ( in this case 13 years ) the dry Arizona climate has caused the rubber to dry up and shrink, this allows the ring to move, as depicted in these photos. The shiny band around the inside of the balancer ring shows the amount the ring has moved.This 3/8" movement is 4 times the maximum allowable parallel misalignment!

Replacing a worn serpentine belt is usually a straight forward procedure, but if the belt is tattered or severely worn on the edges,squeals or chirps, these are signs of misalignment that need to be addressed.
For these conditions we use a laser alignment tool to diagnose the pulley alignment issue..

AUTOMOTIVE and TRUCK ODOR ELIMINATION
Does your vehicle have a peculiar or nasty odor?
Did a rodent die, or a pet have an accident inside?
Did you buy a used vehicle that smells like an ash tray?
Does your A/C smell like a dirty locker room?
WE CAN HELP!
More often than not, after the offensive items are removed and cleaned up the smell remains. Bacteria and fungus continue to grow and cause disturbing odors. We can help to prevent this with our ODOR Elimination procedure!
We started using this on foul smelling a/c systems and have found it works for many other pungent vehicle odors.
Stop by or give us a call, we can make your vehicle smell fresh.
