Additional Notes
- The Volkswagen K 70 cooling system holds 7.6 liters across all three listed engine variants, a figure that represents the total system fill volume rather than a partial or overhaul-specific quantity.
- The K 70 1.6 producing 55 kW shares an identical 7.6-liter coolant capacity with the higher-output 1.6 variant rated at 66 kW, indicating no difference in cooling system volume between the two power outputs within the 1.6-liter family.
- The 1.8-liter K 70 LS rated at 74 kW also carries a 7.6-liter cooling system capacity, meaning the step up in both displacement and power output from 1970-1973 to the 1973-1975 LS variant did not alter the coolant volume requirement.
- All three configurations specify a 24-month change interval under normal use conditions, placing coolant renewal on a calendar-based schedule rather than a mileage-driven one.
- The 66 kW variant covers the 1970-1973 period, while the 55 kW variant spans 1970-1975, meaning both outputs were available during the early years of production before the lower-output engine continued alone into the mid-1970s.
- The 1.8-liter LS variant entered the specification range in 1973, overlapping with the final years of both 1.6-liter variants, yet all three share the same 7.6-liter capacity and 24-month service interval under normal conditions.
