Tech Tips

This page is dedicated to educating our customers. Each month we will have new tips from our technicians and service department.



Coolant Ratio 50/50

Did you know that your engine coolant should be mixed with water at a 50/50 ratio? Adding pure coolant to your recovery tank without a matching amount of water can actually decrease the cooling system performance and coolant protection level. Green coolant should never be added to blue coolant and vice versa, as both are chemically different. Always refer to your owners manual for proper coolant type and fill rate. Most coolant recovery bottles will also have two lines. One is for the coolant level when the engine is warmed up, the other is the fill level with a cold engine.




Did you know...Why to Skip a Gas Station

You should never fuel up your gas tank while the gas station is receiving their fuel delivery. If the fuel tanker is at your gas station, dropping off a supply of fuel, it will stir up any dirt or debris that is normally settled at the bottom of the fuel storage tank. Putting gas in your car while the delivery is being made allows the chance of dirt and sediment making it into your vehicles fuel system. This can result in clogged fuel injectors and poor vehicle performance.





Check engine light is on...now what do I do?

One of the most common caused of a "check engine light" is a loose or improperly seated gas cap. Did you recently fill up the gas tank? Did you start the car before the gas cap was reinstalled? Did you remove the gas cap with car still running? Did the gas cap click when you put it back on? Not sure?

If the car is not running any differently, and there are no apparent changes in the cars performance or drivability you may want to try the following tip. We recommend you remove and reseat the gas cap while the car is off. The car should never be running any time the gas cap is removed. If this was the cause of the "check engine light", the computer should reset and the light will go off in about 3 days to a week depending on your driving habits. If the light continues or comes back on repeatedly, you may want to schedule a service visit.




Low tire pressure light comes on

When the low tire pressure indicator comes on it can be very simple and a quick fix. This is very common this time of year with the falling temperatures. Air will contract with lower temperatures and tires came become deflated. Check and set your tire pressure to avoid this warning light. The proper tire pressure will be noted on the outside of your tire. Proper tire pressure promotes better fuel economy and avoids additional tire wear. A simple check can save you money in the long run.
