Piston Ring Replacement

Piston Ring Replacement Step by step guide on how to install piston rings once the piston has been removed from an automotive engine. Difficulty Scale: 8 of 10 Step 1 - To replace piston rings the piston must be removed from the engine block and replaced (if worn.) For best results the engine block should be bored and new pistons fitted to the connecting rods which should be re-sized. Piston rods can become "out of shape" due to the extreme force they are subjected to. All piston rings are accompanied by a set of installation instructions, these instructions are used to determine the orientation of the piston ring gap. The location of this gap is an important aspect to the performance of the ring. Begin by cleaning the piston thoroughly and securing it firmly in a vise. (Do not tighten against piston, use connecting rod.) New Engine Piston Step 2 - Next, remove the piston rings from the box and separate them into organized piles on a clean surface, use caution as

Engine Overheating causses and repair

Engine Overheating Is your engine overheating? Most engines are designed to operate within a "normal" temperature range of about 195 to 220 degrees F. A relatively constant operating temperature is essential for proper emissions control, good fuel economy and performance. But problems can arise that cause the engine to run hotter than normal, resulting in engine overheating. Your engine's cooling system is filled with a 50/50 mixture of water and ethylene glycol antifreeze. The coolant will boil at 225 degrees unless it is held under pressure by the radiator cap. A 15 PSI radiator cap will increase the boiling temperature of a 50/50 coolant blend up to 265 degrees F. If the concentration of antifreeze to water is upped to 70/30 (the maximum recommended), the boiling temperature with a 15 psi radiator cap goes up to 276 degrees. So obviously the radiator cap plays a significant role in preventing the coolant from boiling and the engine from o
