SUBJECT: 1983 Stanza and Sentra Diesel Block Heater P/N 99998-10251
To assure proper sealing and fit-up of the 99998-10251 block heater in the 1982-83 Stanza and 1983.5 Sentra diesel, NMC-Engineering has determined that a metal spacer must be used with the heater. Pictured below is the proper location of the spacer before (Fig. 1) and after (Fig. 2) heater installation.
This spacer is available at your Servicing Parts Distribution Center as P/N 999AWT3000. The Dealer Net Price of this spacer is 19cts.
