6 Auto Service Locations to Serve You

Summer Car Trouble Overheating

Each changing of the season creates new stressors that can affect the performance of your automobile. Having automotive problems can make you second guess taking that road trip or even a visit to the local swimming hole. What many Portland, Oregon, and Idaho, drivers do is schedule a service appointment at Mac’s Radiator & Automotive Service.

When you schedule any kind of service at Mac’s, they let you know, as a courtesy, if there are any other weak spots in your vehicle that need attention before a failure. Often times, drivers forget to change fluids, fail to top off fluids, or have premature wear in spots that they can’t see. When it comes to summertime problems, it is common for drivers to experience weak batteries, transmission problems, engine stalling, A/C system failures, and overheating.

Carburetors are responsible for mixing air with fuel to obtain the correct ratio for a combustible vehicle’s engine. The carburetor also helps to control the engine’s speed when the gas pedal is pressed. However, you don’t hear much about carburetors in cars too much these days, with the advent of fuel injected engines. But, that doesn’t mean they’ve gone away completely. You’ll still find carburetors on small engine machines, like your lawn mower, rototillers, and other such equipment. That leads us to question, what’s the function of a carburetor and what is the difference from fuel-injection?

How Carburetors Work

The carburetor is a pipe above the engine cylinders with an air pipe and a fuel pipe connected to it.  The air pipe brings in outside air, first through an [...]

Hooray! You’ve decided to get a new car. You may even have your heart set on a certain make and model, but you just can’t decide whether to buy or lease your new car. When it comes to deciding whether to buy or lease, it’s best to consider the pros and cons of each option. Simply put, buying a car means it’s yours to do so as you please whereas leasing a car is similar to an extended rental. Leasing is like renting an apartment versus paying a mortgage for a home. Neither one is right or wrong, you’ll just need to decide which option works best for you, your finances, and your lifestyle.

Why You Should Consider a Lease

On-Board Diagnostic System Check

Beyond your steering wheel lies the dashboard, called the On-Board Diagnostic system or OBD, that shows detailed information on your vehicle’s operation and performance. In short, it’s a uniformed system that allows the vehicle to monitor and communicate via the car’s internal computer system or ECM/PCM. OBD is essential in monitoring major engine functions, electrical condition, and measuring vehicle emissions. A qualified technician utilizes the vital information that is stored by OBD to help determine what mechanical or electrical processes have failed in order to repair a vehicle.

As such, with the new year ringing in, you may want to consider some of these resolutions to make sure your car’s health is as fit and revitalized as your own.

1. Oil Changes

You probably don’t think much about your car’s oil until you suddenly find yourself low on oil or your car makes that inevitable ding and informs you that it needs a change.

However, oil is the lifeblood of your vehicle. Just like the human body, without blood, it cannot function. A car cannot function–at least not function well–without [...]

There are only a few things that can bring more frustration than your car failing you in the morning. Cold weather can cause your car’s battery to malfunction, and some drivers may not understand why. However, by educating yourself on the facts, you will be able to avoid dealing with dead batteries during these frosty months.

In winter months especially, the sub-zero temperatures slow down the rate of chemical reactions required to fire up the battery and start the vehicle. Moreover, cold temperatures also make it hard for the engine to start thus making it require more power from the battery.

Additionally, below zero weather can freeze the battery. While a fully-charged battery is unlikely to freeze, one that is not fully-charged is susceptible to freezing. People also tend to use their cars much less during the cold months [...]

What to Know About Your Car’s Gas Tank

Today, we would like to provide some detailed information for customers to understand the depth of problems that our mechanics face when working on fuel systems.

Gas is highly volatile.

Those Hollywood explosions that you see on TV are typically produced when large volumes of gasoline are detonated. You can easily set your car on fire if you work on fuel system problems without proper training and tools. All it takes is a little spark or contact with hot surfaces for gasoline to ignite on your vehicle and spread like wildfire.

OUCH!!!

We, therefore, recommend that you do not attempt to carry out these repairs yourself and instead seek professional help.

If the air conditioner in your vehicle doesn’t keep you cool anymore, you might be in for an uncomfortable ride even on a relatively mild day. Unfortunately, the problem might not stop there. Some air conditioners can malfunction in such a way that they blow out hot air. There are a few possible solutions to this issue, and it might be a good idea to schedule an appointment with a qualified professional to get your car in working order once again.

Solidified Sealant Trapped In Cylinder

A/C sealants, also known as stop leak, are designed to be a ‘quick fix’ to seal leaks in the A/C system. The sealant is activated when it reacts with oxygen and/or moisture.

However, sealants can crystallize in the system, which can cause more harm to the A/C system. While the leak is covered by the sealant, this seal could possibly only last a few months. Furthermore, the sealant will remain in the system, and it could react with moisture already in the system, which comes from low refrigerant, causing major issues to the whole A/C system.

Listed below are ways in which a sealant can negatively impact the A/C system:

  1. Crystallization can happen in the orifice tube or expansion valve (where moisture is present) clogging or restricting the A/C system.
  2. The crystallization restricts the oil flow back to the compressor causing compressor failure.
  3. If a technician begins the process of recovering the system (without [...]
