How To Add Liquid To Coolant Recovery System

How To Add Liquid To Coolant Recovery System

If your car has a coolant recovery system, you can check the level of liquid on the side of the plastic reservoir. You just open the cap on the reservoir to check whether the coolant looks as though it needs changing or to add water and coolant. Many vehicles have a pressurized coolant recovery system called an expansion tank that makes opening the radiator unnecessary. These systems are considered “sealed” because the safety pressure cap is on the recovery reservoir rather than on the radiator.

  • If you overfill the system, the extra liquid gets hot, expands, and flows out of the overflow pipe. That may not seem too terrible, but because coolant is toxic, it can harm animals or children, who love its sweet taste.
  • If you don’t have coolant on hand and you just need to add a little liquid to the cooling system, plain old tap water will do. But try to maintain a good coolant level by adding a similar amount of straight coolant the next time you add liquid to the system.

You will probably never need to open the cap on the radiator, but if you have to open the cap for any reason, make sure to fill the radiator to the top with a 50/50 mixture of coolant and water before replacing the cap. This addition bleeds the system by forcing any air that may have gotten into the system into the reservoir and out through its overflow pipe when the engine heats up. Follow these steps when adding liquid to the coolant recovery system:

Adding cold liquid to an engine that’s hot can crack the engine block because the hot metal contracts sharply when the cold liquid hits it.

  1. Check the liquid level.

    Look at the outside of the reservoir to see where the level of the liquid in it lies relative to the “MAX” and “MIN” lines embossed on the side, as shown here.

  2. Lift the lever on the safety cap to allow the pressure to escape.

    To keep from burning your hand, place a cloth over the cap after you raise the lever. Then turn the cap counterclockwise to remove it.

  3. If the liquid level is low, add equal parts coolant and water to the reservoir.

    Add equal parts coolant and water until the level reaches the “MAX” line on the side of the container.

Worn Tires

When Is It Time To Replace My Tires?

Tire ReplacementThere are many things that factor into tire replacement. A flat tire or tire that is visibly damaged are obvious reasons. But what are the more common factors? The lifespan of a tire depends on a combination of influences including, the driver’s driving habits, climate, road conditions, tire design, and proper tire maintenance. The big three things to consider:

    1. Tread Wear – Proper tread depth is essential to prevent hydroplaning and skidding. The minimum tread depth is 2/32nd of an inch (1.6 mm).you can use a penny to check tread depth. Simply place the penny upside down into a tread groove. If you can see all of Lincoln’s head, it’s time for tire replacement.

Advanced and unusual wear can reduce the ability of tread to properly grip the road in adverse conditions. Visually check tires for uneven wear, looking for high and low areas or unusually smooth areas and any signs of damage. Motorists should also check sidewalls for gouges, cuts, bulges or other irregularities.

    2. Climate – The heat of summer and cold of winter can wreak havoc on your tires. Too much exposure to direct sunlight, UV rays, and/or heat, can cause cracking in your tires. If the vehicle is parked outside in the elements, and is not driven with frequency, this can accelerate the process. Extreme cold can also factor into tire wear.
    3. Tire Age – Tires are designed and built to provide many thousands of miles of excellent service. For maximum benefit, tires must be maintained properly to avoid tire damage and abuse that may result in tire disablement. The service life of a tire is a cumulative function of the storage, stowing, rotation and service conditions, which a tire is subjected to throughout its life (load, speed, inflation pressure, road hazard injury, etc.). Since service conditions vary widely, accurately predicting the service life of any specific tire in chronological time is not possible.

Lofton Motorsports is unaware of any technical data that supports a specific tire age for removal from service. However, as with other members of the tire and automotive industries, Lofton Motorsports recommends that all tires (including spare tires) that were manufactured more than ten (10) years previous be removed from service and be replaced with new tires, even when tires appear to be usable from their external appearance and if the tread depth may have not reached the minimum wear out depth. Vehicle manufacturers may recommend a different chronological age at which a tire should be replaced based on their understanding of the specific vehicle application; Lofton Motorsports recommends that any such instruction be followed. Consumers should note that most tires would have to be removed for tread wear-out or other causes before any prescribed removal period. A stated removal period in no way reduces the consumer’s responsibility for tire replacement as needed.

Lofton Motorsports recommends that you regularly inspect your tires. An inspection of the tires should be incorporated during routine vehicle maintenance procedures. If tire damage is suspected or found, it should be carefully assessed by a trained tire specialist immediately.
