Your Polyair suspension is designed to provide a lifetime of reliability. However, in order for it to work to the best of its ability, it's crucial to perform simple routine maintenance every so often.
Unless you live in a climate that doesn't include snow, winter is bringing with it freezing temperatures, muddy, slushy roads and the routine slipping and sliding of your normal commute. Fall is a great time to make sure your Four Wheel Drive Suspension is up to the challenges that winter has in store.
Check Your Air Pressure
When your vehicle is unloaded, check the air pressure in your Polyair springs. Make sure the minimum recommended pressure of 5 PSI is maintained. Minor fluctuation in air pressure is to be expected when the outside temperature fluctuates, but if you are losing air consistently, you may have a leak.
If you think you may have a leak in your air suspension, you can perform a very simple leak test to see whether or not a leak is occurring. Just create a mixture of soapy water, consisting of, one part soap to four parts water and spray the solution on all of the inflation valves and fittings. If bubbles appear, then you have a leak in that area.
Inspect your system
Every fall, before the really nasty weather starts, it's a great idea to physically inspect your complete Polyair suspension to make sure that nothing has been knocked loose by road debris. The parts you should be checking include:
Heat shields - Check to make sure all of your heat shields are still mounted securely and that there is still ½" to 1" of space left between the heat shield and the heat source.
Hoses - Make sure all of your air hoses are still attached securely to the vehicle and check to make sure there isn't any damage to the hoses. Re-attach any loose hoses and replace any damaged ones.
Air Springs - Make sure there isn't any sign of rubbing on the air springs. There should be at least ½" of clearance around the air springs when they are inflated to approximately 60 PSI.
Compressors - If you have an air compressor installed in your vehicle, check the filter for debris and clean if necessary. Make sure you also refer to your compressor's owner's manual to see if you need to add an air line antifreeze.
Valve Caps - Make sure your valves have the screw-on caps attached. The valve caps will keep out snow, salt and water so your valves don't freeze and/or rust.
A simple yearly inspection of your Polyair suspension in the fall, will ensure its proper operation for years to come.
