Engine Hydration for Suwanee Drivers: Role of Your Water Pump

Posted November 19, 2017 3:32 AM

The cooling system in an engine has five components: the radiator, the radiator cap, the hoses, the thermostat and the water pump. The water is literally the heart of the system. Just as your own heart keeps your blood circulating through your body, the water pump keeps coolant circulating through your engine.

The water pump is driven by a belt, chain or gear and only operates while the engine is running. It has a limited life span and sooner or later will have to be replaced. You can check your owner's manual to find out how long your water pump should last. Some can fail at only 40,000 miles (64,000 kilometers), but almost all of them fail by 100,000 miles (160,000 kilometers).

Water pumps don't gradually wear out; they fail. In other words, they're either working or they're not. A failed water pump has to be replaced.

Water pumps can fail in two ways: they can spring a leak or their bearings fail. Leaks can come from a cracked pump but usually develop at the gasket where the pump attaches to the engine.

If you hear a low-pitched grinding sound coming from the water pump, it's time for a new one. If you see coolant leaking in the area near the pump, it needs to be replaced. Also, coolant on the driveway could indicate water pump failure. Many water pumps aren't visible because they're under a plastic cover, so you may have to take your vehicle to D.C. Auto to know if the water pump has failed. If your water pump is run by the timing belt, then it should be replaced when you replace the belt. Most timing belts need to be replaced at around 60,000 to 90,000 miles (100,000 to 150,000 kilometers). The labor for replacing a timing belt is about 90% the same for replacing a water pump, so it's cost-effective to take care of them both at the same time. Also, if your water pump develops a leak (if it's powered by the timing belt), you have to replace the timing belt as well since contamination by coolant fluid damages the belt. It just makes sense for Suwanee residents to replace both of these parts whenever either one needs it.

Replacing a water pump at D.C. Auto is a vehicle care issue that almost all of us Suwanee residents face eventually. They don't last forever. On the other hand, we can extend the life of most of the components of our vehicle through preventive maintenance. Just as exercise and diet keep our heart healthy, regular check-ups and fluid changes will keep our vehicles healthy. Talk to your friendly and knowledgeable D.C. Auto service advisor.

Testimonials

  • Tom and the folks at D.C. Auto are simply the best. I've had a good bit of work done on my vehicles over the years and have always been treated well. They're honest, thoroughly explain the problem and charge reasonable prices; everything that you could ask for in a mechanic.
    -Tony D.

  • Been a DC Auto customer for almost 6 years now. Tom and his crew are top people - never disappointed. Always upfront and honest. Never "pushed" an addon or any sorts like that. One can only smile at a couple of pointed and personal reviews here. Never had "that" problem at DC Auto. Would recommend.
    -Raju S.

  • Always helpful, always cheerful. Honest estimates, and won't recommend work that isn't needed. If the problem falls outside of their ability, they will tell you right up front. I've taken multiple cars there for years and have never had a problem.
    -Charles P.

  • I have been going to DC Auto since it first opened. The staff is highly knowledgeable and courteous. Tom is one of the most honest men I know. He is highly ethical and never tries to "up-sell." The work is always superior. After all these years I can't see myself going to any other auto service company.
    -Louis C.

  • Awesome service at a great price. Always stands behind his work. Tom runs a great shop with great employees and always a smile and a story. Honest no gimmicks what all businesses should be.
    -Ron T.

  • I have been a customer with DC Auto for close to four years. I have NEVER had an unpleasurable experience. They know who I am when I pull in and do their very best to keep me and my family safe on the road! The crew at DC Auto is outstanding and the customer service is phenomenal.
    -Jessica R.

  • 5 stars...the guys at DC Auto have taken care of our family's cars since they opened. I just brought in my 2005 Honda Pilot with an oil leak. They found the leaky oil pan and replaced it. Not surprising on a 205,000 vehicle - drain plug was getting stripped out. She STill runs like new because I keep it maintained (at DC Auto). Fact is they do great work, they're honest and prices are good. No stupid high pressure. I trust them. Highly recommend.
    -Jerry M.

  • Fantastic service shop my husband and I (as well as several friends we recommended them to) have used for years. I know "honesty" isn't often a word associated with car mechanics but Tom and Rob have always shot us straight about our vehicles, and I know it to be true because several times, their advice to us has actually cost them a repair job (and saved us money). They typically get us scheduled same day or maybe the next, and the turnaround time is speedy. For hometown feel, honest opinions about your car, great service techs and reasonable prices, use DC Auto.
    -Megan H.

  • DC Auto is the what every car repair shop should be. These guys are great! They easily find what is wrong and fix it in a timely manner. The other reason I will refer anyone here is because their pricing is very reasonable. This place is better than others and WILL NOT overcharge you for every little and last thing. Go to this place for any car maintenance big or small. Tom and Robert in particular are who I would suggest, although everyone on staff is very good.
    -Dan C.

  • 10/10. Would recommend. Personable and knowledgeable mechanics that don't try to rip you off. Great quality work for reasonable pricing.
