Action
On both sides of the vehicle, install a revised upper strut bearing assembly. If the vehicle was built before February 2005, it may also be necessary to install a lower spring seat isolator if one is not already present. Refer to the following Service Procedure.

Service Procedure
Review safety procedures in ALLDATA Repair before beginning.

1. Remove the strut and spring assembly.
2. Disassemble the strut and spring assembly.
3. If the springs do not have a rubber isolator on the bottom spring coil, install isolators. Clean off any dirt prior to installing the isolator. The isolator should be installed 4" (100 mm) from the end of the coil (Figure 1).
4. Reassemble the strut and spring. During reassembly, make sure the lower spring coil is butted up against the lower spring seat on the strut and the upper spring coil is butted up against the upper bearing assembly.

NOTE:
Install all new fasteners during reassembly.
Vehicles alignment is not required after this repair.

Understanding Coolants

All-season coolant used inorganic acid technology and worked great for almost 30 years.

In the 1960s, coolant was changed twice a year. In the fall, antifreeze with ethylene glycol-based coolant was put into the engine to prevent the coolant from freezing and cracking the block when a cold front hit. Often, if the engine got hot, the antifreeze would boil off. In the spring, the engine would be drained and filled with water and maybe a small can of an anti-corrosion treatment.
