Cooling System Repair & Maintenance

 

Your radiator protects your engine and air conditioning condenser from overheating. It also plays an important role with the computer controlled system. Car over heatingAn engine temperature sensor actually tells the computer what the engine temperature is so the computer can adjust the air and fuel mixture and engine timing. The efficiency of the radiator directly effects the efficiency of your engine.

 

That's why flushing the cooling system and pH balancing the coolant is recommended at least once every couple years.

 

Our coolant system power flush continuously forces fluid under pressure through the engine, radiator and heater core in both directions at different times to remove contaminates. We pressure test the cooling system for leaks, clean the recovery bottle and pressure test the radiator cap. The system is then refilled with the proper mix of coolant and water to reach the -35 degrees for winter protection.

Checking coolant fluidWe’re often asked questions about the cooling system – the system that cools your engine and keeps it at the proper operating temperature. Let’s examine the topic in two areas: first the coolant itself and, second, the parts that make up the cooling system.

 

The coolant in your car or light truck is the mix of water and antifreeze that circulates through the engine to draw off heat. First, you need to have the proper amount. If you don’t have enough coolant it can’t keep your engine cool.

You also need the right kind of coolant. Different makes of sedans and other vehicles require different coolant formulation to protect against corrosion.

 

Finally, your coolant needs to be fresh. Over time and miles, the anti-corrosion additives in the coolant are depleted and the coolant can actually start to eat away at the cooling system parts. Your owner’s manual and your Westgate High-Tech Auto Care service adviser in Omaha Nebraska can help you with the recommended coolant replacement schedule and make sure you’re getting the right type of coolant.

 


Westgate High-Tech Auto Care Tech Question On Your Cooling System

Westgate High-Tech Auto Care Tech Question:
I was driving down the freeway in Omaha and smoke started coming out of my car. I pulled over and called my husband. I had to be towed to my Omaha mechanic. He said my car had overheated. What can I do to prevent that in the future?

Westgate High-Tech Auto Care Answer:
Oh, sounds like a rough experience. Unfortunately overheating is the most common engine failure in Omaha . It's also one of the easiest to prevent.

The basic idea is this: you need to keep enough coolant/antifreeze flowing through your vehicle engine to keep it cool. Problems come for Omaha drivers when they develop leaks in their systems – like in the radiator or a hose – and the coolant leaks out. Sometimes the coolant gets so contaminated that it blocks up the radiator so the coolant can't get through. Enough of that and you end up broken down on the side of the road.

Your owner's manual recommends a schedule for coolant replacement. That's because your coolant actually becomes corrosive over time and starts to eat away at the cooling system, causing leaks or blockages. New coolant stops that process.

Ask your friendly and knowledgeable pros at Westgate High-Tech Auto Care about inspecting your vehicle cooling system for leaks, spongy hoses and other damage. If it's time to replace your coolant, hoses or other cooling system parts, have it done right away at Westgate High-Tech Auto Care in Omaha. Prevention at Westgate High-Tech Auto Care is the key.
 


 

Thermostat

The thermostat is part of your cooling system. Omaha residents' vehicle thermostats perform a similar function to the thermostats in their homes. At home, you set your thermostat to maintain a comfortable temperature range. When your home gets too hot, the air conditioning kicks on and when it gets too cool, the heater turns on.

Now your engine also has an optimal temperature range: warm enough to run efficiently and not so hot as to cause engine damage. Your vehicle's thermostat is a valve between the engine and the radiator. When Omaha residents first start a cold engine, the valve (thermostat) is closed, allowing the coolant surrounding the engine to warm up to the proper operating temperature. As the coolant gets hotter, the thermostat opens, allowing coolant to flow through to the radiator to be cooled. The thermostat opens and closes to keep the engine within a certain temperature range.

Now thermostats are rated for a specific temperature depending on the engine – not a one size fits all proposition. Thermostats are subject to normal wear. Proper operation depends on a special wax that expands as it heats up to open a spring-loaded valve. A worn thermostat could stick in the open position causing the engine to run too cool. This is inefficient and could affect performance and fuel economy. If a thermostat sticks in the closed position, the engine can be subject to the results of overheating.

There isn't a specific routine for Omaha residents to maintain their thermostat, but maintaining the cooling system by changing the coolant/antifreeze on schedule will make sure the coolant has enough corrosion inhibitors to protect the thermostat and other system components. Cooling system experts and the team at Westgate High-Tech Auto Care in Omaha recommend replacing your thermostat when you do a coolant flush or exchange. Also, thermostats usually wear out faster than your hoses, so if a worn hose replacement is performed, replace the thermostat at the same time.

If your temperature warning light comes on, have an inspection of your cooling system right away. This could be a thermostat . The thermostat could also be the culprit for Omaha residents who aren't getting hot air when they turn on their heater.

The thermostat is a relatively inexpensive part that stands guard between you and catastrophic engine damage. Follow your owner's manual instructions, or check with your friendly and knowledgeable Westgate High-Tech Auto Care service advisor to see if it's time for a cooling system inspection or service.
 

 


Simple Answers from Westgate High-Tech Auto Care for Omaha: Water Pump
Simple Answers Service Intervals

Question:
My water pump went out and it costs much more to replace than ones I've had replaced in the past. My Omaha technician said it's because of where it's located. Why is that?

Westgate High-Tech Auto Care Answer:
Some water pumps are driven by the serpentine belt and are bolted on out in the open with the alternator and air compressor and such. Other water pumps are driven by the timing belt. These water pumps take a lot of labor to access and replace. I suspect your current vehicle has a water pump that is driven by the timing belt.

Water pumps are fairly simple devices that circulate engine coolant/antifreeze around the engine and out to the radiator. Like any mechanical device, they eventually wear out. Although having a cooling system service done on schedule at Westgate High-Tech Auto Care will extend the life of your water pump and its seals and gaskets, it will eventually fail and need to be replaced.

Those water pumps that are driven by the timing belt (the belt that controls when your engine intake and exhaust valves open) are attached directly to the engine block. The timing belt system has a protective cover. The serpentine belt and all the accessories are located over the timing belt cover. So getting to the water pump requires removing a lot of parts which then need to be replaced.

When the water pump must be replaced at Westgate High-Tech Auto Care in Omaha, it is a good idea to go ahead and also replace the timing belt, timing belt tensioner and idler pulleys. First, because the timing belt may have been contaminated by leaking coolant; second, there is a schedule for replacing your timing belt and you might as well make the modest additional added expenditure while everything is taken apart to avoid the same labor cost down the road.

By the way, the reverse is true as well: When you are replacing your timing belt on schedule, go ahead and replace the water pump at the same time. It would be a shame to spend the money on one of these replacements only to have to do it all again in a few months because the other then needs replacement. Do them at the same time and start the clock over for both.
