Heater strut replacement

This section covers heater strut replacement. Do not attempt to replace the heater strut
until all other possibilities for poor performance have been considered.

If heater strut replacement is needed, order a replacement heater strut kit (

Table 9-1

 on

page 79). Refer to 

Figure 8-3

 on page 70 for item letter references.

 WARNING

BURNS
Use heat resistant gloves and clothing when removing probe. Do not attempt to work on
the probe until it has cooled to room temperature. The probe can be as hot as 427 °C (800
°F). This can cause severe burns.
