 TOC

Automotive with CM870


Use protective caps from the Air Handling Clean Care Kit, Part Number 4919403 and Part Number 4919425, at the end of the rear EGR connection tube that interfaces with the EGR cooler before working the tube into position, to reduce the possibility of introducing dirt or debris.

Install the p-clips onto the rear EGR connection tube.

Make sure the tube insulation is properly and fully located under the p-clips and that the p-clip rubber sleeve does not block the mounting hole.

Install the rear EGR connection tube and the p-clip mounting capscrew and nuts.

Hand-tighten the capscrew and nuts.
