  Q: How to Maintain and Fix a Piston on Chrysler Voyager?

  A:

  To begin, replace the cylinder head to expose the cylinder bores and use a good reamer to even out the ridges, leaving the piston tops covered. Before removing the reamer, mark each piston with its cylinder number. At this stage, get rid of the Oil Pan and mark the ceiling of the rod and cover with the cylinder number for clarity. Direct the directional stamping on the pistons toward the engine front and take out the pistons and connecting rods from above by rotating the Crankshaft to make each connecting rod central in the related cylinder bore. Take out the Balance Shaft Assembly and the bolts that secure each rod cap, then push the piston and rod assembly off the crankshaft's journal without accidentally nickiling them. Following removal, put on the bearing cap on the mating rod, as pistons and rods are maintained all at once. When you install the compression rings, apply them so the gaps do not match those in the oil ring rail and have the ends of the oil ring expander join the rail gaps correctly. Soak the piston head and rings in clean engine oil, then put the ring compressor over the piston to keep their positions steady. The stamp should be facing the front, as before. Rotate the crankshaft so the connecting rod journal is in the center of the cylinder bore, fit in the piston and rod and slide the part over the crankshaft journal. With the piston on the hammer handle, tap down to line up the connecting rod in place. Never use the same cap bolts; instead, cover the threads of the new bolts in clean engine oil, assemble the cap alternately and thread each bolt by hand, without a torque wrench. After that, fasten everything else to 27 Nm plus 1/4 turn and ensure there is proper clearance between the connecting rod and the feeler gauge.

  Q: How to Properly Remove and Install Pistons and Connecting Rods in an Engine on Chrysler Voyager?

  A:

  When removing the pistons and connecting rods, you must first bid farewell to the cylinder head. First, run a reliable ridge reamer through the bores to get rid of the ridge at the top, ensuring the tops of the pistons are covered. Pistons should be stamped so the front faces the front of the engine. After that, take out the Oil Pan and the Balance Shaft Carrier Assembly. Put a permanent ink or paint mark on every connecting rod cap with the related cylinder number to show the correct pairing, instead of using a number punch or stamp: this will help prevent any damage. Be careful not to damage the fracture rod and cap as you remove the bolts and don't use them again afterward. After rotating the Crankshaft, line up a rod in a cylinder bore and carefully pull out the piston and rod without touching the crankshaft journals. Once the worn bearing is out, install the bearing cap on the rod of the same assembly and perform the same procedure for all the assembly piston/rod pairs. When installing, check that the compression ring gaps aren't aligned and that the oil ring expander ends go against the rail gaps that are placed correctly. Put both the piston head and piston rings into clean engine oil, then put the ring compressor over the piston so the ring locations stay the same. Once the bottom is on, place the directional stamp on the piston pointing toward the engine's front. Rotate the crankshaft until the rod's journal is in the bore in the middle, push the assembly in and place the rod over the crankshaft journal. Strike the piston down using the handle, directing the connecting rod at the same time while you do so. Before you install the cap bolts, coat them with clean oil and fit them in place just hand tight. Do not use the torque wrench in the second part of the last step; tighten the bolts until they reach 27 Nm and turn them an extra 1/4 turn. After that, test the connecting rod space with a feeler gauge and reattach the Balance Shaft Carrier Assembly, oil pan and cylinder head.
