Fluids and Filters

Is It Time for an Oil Change?

The oil in your car lubricates the engine and keeps all the parts running smoothly. Over time, the oil gets dirty, thick and sometimes even sludgy. You don’t want that flowing through and clogging up an expensive piece of machinery! You know you need an oil change when:

  • You’ve driven more than 3,000 miles since your last oil change (check your vehicle manual for ideal miles driven between changes).

  • It’s been a year since you’ve had your oil changed.

  • Your oil level is low.

  • Your oil, when you check the level, is dark black-brown on the stick.

Sherwood Auto Repair will choose the type of oil that’s best for your vehicle; usually as recommended by the manufacturer. With each oil change, Sherwood Auto Repair will also:

  • Change the oil filter. Changing the filter keeps your oil cleaner longer.

  • Inspect your air filter and recommend replacement only if needed.

  • Check your vital fluid levels, such as battery water, automatic transmission fluid, coolant/antifreeze, and brake fluid.

Heating & Cooling

Is your car running hot?

Cooling system failure is the #1 cause of engine breakdowns on the highway. A little maintenance can go a long way to preventing a potentially expensive engine problem and a lot of inconvenience for you and your family.

Signs of Overheating

Keep an eye out for the following signs and symptoms; your car or truck may be telling you it needs a little cooling system care:

  • Dashboard temperature gauge shows the car is in the red or running hot.

  • Any colored fluid is leaking from the engine.

  • Steam is coming from the engine.

  • Car engine smells “hot”.

  • Engine belts and hoses are more than 5 years old or are showing signs of wear, such as cracking.

  • Auto manual recommends maintenance, such as replacement of anti-freeze.

At Sherwood Auto Repair, our ASE-certified master technicians will perform a professional inspection of the system and provide you with a complete analysis of the current conditions and the estimated cost of repair.
