My GMC 1000 Series truck has been a dependable partner for my business for years now. My question is, how do I know if its time to change the belts and hoses?

Ideally, the hoses and belts should be changed every 35,000 to 60,000 miles that should take around 3-5 years. However, if you notice that the truck is emitting more exhaust than usual or that it is starting to shake and vibrate, then it's time to take the truck to a mechanic and have the belts checked. Examine the timing belts and fan belts. Do not allow it to reach the point when the belt breaks. This will cause the truck to breakdown and unable to even start. A timing belt break could also affect other engine parts and cause valve damage. Once you replace the timing belt, then also consider replacing other usually affected parts such as the water pump, belt tensioner, thermostat, and camshaft seals.

How often do I need to change my GMC 1000's spark plugs and how do I keep it in good condition?

Turn off the engine and use safety rubber gloves before proceeding. The recommended replacement interval for your truck's spark plugs is indicated in the manual. In general, the recommended interval is every 30,000 miles. However, there are a few telltale signs that indicate if the time is up for the spark plugs.
