The coolant diverter for the NRS cooler is being left out during engine overhaul, short block builds, transmission cooler repairs, and repairs to the NRS cooler water manifold. When the diverter is left out, coolant supply flow will dead head with return flow causing multiple NRS cooler failures and may cause engine failure. Solution
After the service is done, the coolant diverter will be installed in order to direct coolant supply flow to the NRS cooler.
