An Ounce Of Prevention – Antifreeze and Coolant Service

The Importance Of Antifreeze/Coolant Service Take a look at these photos, notice the brown areas of clogging and material at the bottom of the radiator? Nowhere is this more frequent than on engines using an aluminum cylinder head, and cast iron block…like most modern cars. And we also find this clogging not just in radiators, but also in heater cores. A heater core is a radiator-like device used in heating the cabin of a vehicle. Hot coolant from the vehicle's engine is passed through a winding tube of the core. Fins attached to the core tubes serve to increase surface for heat transfer [...]

Car Batteries – Facts About Lead Acid Or AGM Types

Why AGM Batteries? Absorbent Glass Mat batteries (AGM) have been a market favorite for the past decade for reasons of capacity and durability. These batteries are becoming much more common in European and imported autos like Audi, BMW, Mercedes, Mini Cooper, Volvo. How They Work In principle, the AGM batteries work like any other lead battery. However, the AGM batteries, compared to flooded batteries, have several significant improvements that make them more efficient. Additionally, just like other types of batteries in the market, they have their advantages and disadvantages. Choose The Right Type The right battery for your car will give good service from 3 to 5 years, maybe longer if well [...]

BMW and Mercedes Benz – Ceramic and Aluminum Fuse Problems – How and Why

About The Problem One of the more common electrical issues we see with the vintage Mercedes vehicles are problems related to the fuses and fuse box. Like many of the older European models, these cars were designed and engineered with identical or similar parts, in this case, the ceramic and aluminum exposed fuses. At the time, this was an excellent solution, but now, some 20 years later, we frequently see a series of pattern failures on vintage Mercedes, and almost always the same issue over time: fuse failure. While the ceramic and aluminum fuse failure is particular to older European vehicles; however, it’s a simple problem to fix in [...]

Evaporative Emission (EVAP) Faults – Check Engine Leaks

Evap System The evolution of evaporative emissions systems has been driven by changes in emissions standards. While some vehicle manufacturers have introduced very different designs along the way, most use primarily used a vacuum-based design as a foundation. The exceptions are its hybrid electric vehicles, which use an evaporative leak check monitor (ELCM) similar to the Toyota key-off vacuum pump system, and 2011-03 Ford Fiestas, which use a natural vacuum leak detection (NVLD) system similar to the one used by Kia and BMW. What is It The oil and fuel in your vehicle give off vapors that are very [...]

Why An Oil Filter Housing Leak On A BMW Engine Shouldn’t Be Ignored

What Happens Oil leaks on any engine are both a nuisance and fact of life but few can cause damage like the BMW oil filter housing gasket. I haven't seen too many higher mileage BMWs that don't have some kind of oil leak that goes without repair. The N 54 and series of engines have been excellent, and very durable, once the oil leaks are handled. However, they are not engines that do well when the oil leaks are not promptly and professionally addressed. If there's one oil leak on these engines that is critical to address, it's the oil filter housing gasket. This [...]

How to Fix Squeaky Brakes

What Causes Breaks to Squeak? Don't expect brakes to be totally quiet—sometimes, they're going to make some noises. Don't panic, because a squeaky brake can stop a car just like a silent one can. What causes the squeal? Modern brakes use a cast-iron disc squeezed between two brake pads lined with friction material. Under the right conditions, the disc, the pads and the caliper they're mounted in can start to vibrate—in exactly the same way a violin's string vibrates when stroked by the horsehairs on the bow. Most brake squeals occur at a single discrete frequency. The speed of the vehicle [...]

Mercedes Brake Line Repair – Rust Damage

Mercedes Brake Line Repair - Rust Damage If you look at this late model Mercedes, you'd think that it hardly would have a problem with rusted brake lines, a safety issue that has afflicted domestic cars for decades, but until recently, was quite rarely seen on European autos. Why This Happened We've seen the transition from the older bonded phosphate brake lines used on the European cars that never rusted, to painted lines. We've found that the painted lines are much more susceptible to cracking the coating and then rusting the exposed metal. But knowing where to look is the [...]

AMC Tech Q & A – Oil Change Intervals

Question A question we sometimes get is - "Curious about oil changes. Synthetic has been around 15000 miles. Looks like you recommend 5,000?" Answer To which we are glad to reply, "Great question!" Yes, we do recommend a shorter interval for older cars. We have an expression, "Oil is cheaper than metal," I'll explain. We all know that oil is used to lubricate the engine components to maximize wear and tear, it also serves transfers heat and helps filter out contaminants from engine operation. Here's Why First, let's address why we change the oil. It's for two reasons, one is [...]

BMW – Computer Diagnostics and Programing

Get On The Can Bus I’m old enough to remember the days when cars only had one computer, the engine control unit, aka the “ECU”. Now a days most cars have not not one, but dozens of computers or modules all talking to each other over what is called a Controller Area Network or “CAN Bus”, somewhat like the “USB” (Universal Serial Bus) of your home computer. Cool idea as it simplifies running hundreds of individual wires, but it really ups the technology service game. Here we are programming a replacement part, known as RDC module, that is part of [...]
