Service campaign TSC26001

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Subject: The power steering cooler may begin to leak on the low-pressure side of the system. This fault will need to be inspected and corrected if any seepage is present Problem: Power steering cooler fittings have an inconsistent machined edge; this edge prevents the O-ring from sealing resulting in a slow seepage. Applies To: Certain 2019-2026 Rosenbauer trucks have been flagged as possible candidates. Rosenbauer will be supplying a list to service partners and notifying customers. Assistance Needed: Dealers to follow the Technical Service Campaign instructions and inspect the listed candidates for faulty power steering coolers. If known leaks are present, submit a CRM ticket with an image of the leaking cooler fittings. Resolution: If this problem is found, a replacement Setrab cooler with higher quality standards and machining will be supplied at no cost to customers. This correction does not change the connected hoses and does not require a full power steering drain.
