At TSB Undercar Specialists we see a lot of problems caused by neglected hoses, belts, and filter maintenance from our customers here in Flagstaff. These items are durable and last a long time, but not forever, and rarely give warning before they start causing trouble. For this reason, people often find themselves inconvenienced by a failed belt, hose, or filter; it’s one of those things that simply slip your mind until it causes you trouble.

Rubber belts experience two types of wear; mechanical, and age. While you run errands around Flagstaff, your belts are wearing out. The belts drive everything on your engine - your alternator, water pump, A/C, power steering, and even the camshafts and valve train. Constant wear and tear from moving pulleys coupled with repeated heating up and cooling down eventually wear a belt out completely. Belts also dry rot with age and become weak and brittle after years of contact with the environment. Allowing our expert team at TSB Undercar Specialists to properly inspect and replace these parts is key to maintaining a reliable vehicle.

Hoses are susceptible to wear from heating, cooling, and age. Hoses generally contain pressure, which constantly puts stress on them while the engine is running. For this reason, a small tear or pinhole can quickly develop into something much more serious, and suddenly you are rapidly losing coolant, fuel, or vacuum. Damage can occur from moving parts, repeated expansion, or dry rot. Hoses should be changed before a problem arises if they are visibly cracked, damaged, or worn broken hoses cause huge messes, overheating, fire hazards, and are generally inconvenient.

Modern fuel filters tend to be overlooked during maintenance as well since they last a long time and are tucked away in odd locations; many drivers here in Flagstaff forget to have them changed at correct intervals. A clogged filter results in strain on the fuel pump, misfires, low power, etc., as it starves the engine of fuel. Allowing our team at TSB Undercar Specialists to replace your fuel filter is cheap and easy; if your manual recommends a filter change or you can’t remember the last time it was done, have a new one installed. Air and oil filters are part of routine maintenance, and while they are certainly important, a reputable shop will always inspect them or recommend replacement. Fuel filters can’t be checked and don’t get replaced every 3,000 miles, so it’s important not to forget about them.

If you’re experiencing trouble from failed belts, hoses, or filters, or think it may be time to have them inspected or changed, come see one of our expert mechanics at TSB Undercar Specialists. One of our technicians will be happy to take a look at your car, truck, or SUV and advise you on what to do next.
