Coolant Type:
Water-glycol mixture (50/50) with rust inhibitor.
Rust:
Susceptible to corrosion, especially in wheel arches, sills, and door bottoms.
Hydraulics:
Potential for leaks in clutch and brake systems due to aging seals and lines.
Suspension Wear:
Wear in rubber bushings, kingpins, and potentially hydrolastic fluid in later models (though not typically in early 1961 models).
