The air conditioner of my Subaru GL is still working but does not produce as much cold air as needed, especially during hot days. Why does the temperature keep on fluctuating?
Fluctuating temperatures from your car's air conditioning system are usually caused by five things: coolant leaks, a faulty compressor, a faulty thermostat, electrical damage or bacteria. Inspect if there is damage to hoses and seals which might cause coolant leakage. Also, observe if there is some noise present. That is a sign of a faulty compressor or the usage of the wrong type of compressor lubricant. This contributes to unstable temperatures too. The presence of bad odors indicates that mold and bacteria has built up inside the system. Fix this by using an anti bacterial treatment such as household disinfectant. Have the thermostat and electrical wiring checked by the mechanic as well. Sometimes, the air conditioning system may be okay mechanically but refuses to work well as it should because of problems with the electrical system.
I bought my Subaru GL when it was still a little bit rusty. I had it undergo sandblasting treatment. I am pretty much happy now that my GL is rust free. What measures do I need to take in order to prevent rust from happening again?
Rust is one of the biggest enemies of any vehicle. Take note that both interior and exterior parts can be prone to it. Rust formation is not merely a "cosmetic" concern. Its presence in your car's structure can cause decreased resistance from impact. When it spreads into the internal parts especially the engine, driving performance and safety will be greatly compromised. You deserve a pat on the back for getting rid of the rust on your GL, but preventing rust formation is a long term effort and requires developing good habits. First, always park carefully. Choose your parking space well. Avoid parking in grass, dirt or any moisture-filled surface if you can avoid it. Even asphalt-paved or cement surfaces are not safe from moisture either. Consider applying a layer of asphalt sealer. Always clean your GL to take off mud and grime using running water and a non-detergent soap. Make sure that everything is dried thoroughly afterwards using a non-abrasive car cloth. Consider applying rust inhibitors on the metal panels but not on hot surfaces such as the catalytic converters and exhaust components.
My Subaru GL has been with me for a long time and I think the interiors are already in dire need of a general cleaning. What are the things to keep in mind to guide me in detailing my GL's cabin?
A well-maintained interior enhances your driving experience by ensuring comfort for the passengers. The first things that you would probably have to pay attention to are the upholstery and the floor carpets. Do they only need vacuuming or complete replacement? Nonetheless, vacuum the panels and the seats underneath once you have removed the mats and the fabric. Start from the top and work your way down. If you decide to keep the existing upholstery, you can use a foam cleanser on a damp cloth to rub away all stains and dirt marks. Wash and shampoo the seats. When you get to the dashboard and doors, use compressed air and detailing brushes to eliminate stubborn accumulated dust. Move on to every cranny and crevice, including the vents, and brush the dust away. Finally, finish it all off by wiping surfaces with a mild all-purpose cleaner.
