Spring is here in most areas of the country, unfortunately not here as our snow is melting and we are undergoing a flood of record proportions, but none the less it is time to get the vehicles ready for spring.  Check the tires, and the spare, I know I preach this a lot but it is easily ignored Check wipers or just replace them, spend the extra couple bucks and don’t use the ones you have to build buy the exact fit the performance is well worth the extra $. Check fluids, all of them, defer to your owner’s manual for instructions on how to check transmission there are numerous methods for different models. Be sure to use the correct fluids for replenishment here again use what the manufacture recommends. Check belts and hoses as I have stated many times a visual inspection is still the best preventive maintenance. Give the hoses a squeeze checking closely by the connections if it is swelling or feels squishy replace. Lots of cracks or glazed or frayed replace the belt. Check your lights not forgetting the license plate light, usually are out on step bumpers, many law enforcement are using this as an excuse for a traffic stop. Lube all the hinges, I know this is supposed to be part of a lube but I have never seen all of them lubed IE door, trunk and hood hinges including latches if your hood sticks and the hinges are lubed, lube the latch 9 out of 10 it will fix the problem. Don’t neglect the key locks mainly if you have a remote unlock.  Check the filters including the cabin air and vapor canister if you have them. Remove all unnecessary items.  Run it through the car wash including under carriage here again spend the extra couple bucks and get the good wash I guarantee your rig will seem to run better.
