Technical Service Bulletin
Technical Background
A minor coolant leak is possible during the break-in phase of the coolant seal on the coolant pump. The dry
coolant marks are normal.
Production Solution
Not applicable.
Service
During a service visit, if dried coolant is found around the coolant pump but there is no customer complaint about
the cooling system, no repair is necessary. The coolant pump should not be replaced.
Optionally, the integrity of the coolant pump can be tested with the following steps. Before proceeding, clean the
dried coolant off of the engine with tap water. This will make it easier, on future visits, to know if there is an
ongoing issue.
1. Bring the engine to operating temperature, then turn the engine off.
2. Pressurize the coolant system with 1.5 bar for 10 minutes.
3. Check for fresh coolant leaks on the vent holes of the coolant pump.
4. If no fresh coolant is visible, the coolant pump is working as designed and should not be replaced. If fresh
coolant leaks are found, continue to diagnose the issue outside of this bulletin.
