Front & thermal systems

Evaluate coolant-valve reduction gears separately from wetted seals, including temperature, starting torque, coolant compatibility and leakage.

Lubrication applications

Review valve-drive lubrication separately from coolant-contact seals.

Sample comparison checklist

Contacts: Reduction-gear contacts and coolant-exposed seals.
Comparison: Contact materials, coolant, temperature, current material and application boundary.
Record: Starting/running torque, seal compatibility and leakage.

Compare on the actual part under matching conditions; discuss sample quantity and the evaluation method.

Review gears, output supports and links in grille-shutter drives.

Sample comparison checklist

Contacts: Reduction gears, output-shaft supports, linkage and pivots.
Comparison: Contact materials, current lubricant, temperature, load and dose.
Record: Starting/running torque, noise, retention and migration.

Compare on the actual part under matching conditions; discuss sample quantity and the evaluation method.
