Thermostat Housing and crossover pipe
I'm getting ready to replace a leaking thermostat housing on a N18 engine with 155,000 miles. My question to those of you who are more knowledgeable, should I go ahead and also replace the coolant crossover pipe while in there? I see post that state the plastic pipe becomes very brittle after so many miles.

Are you going to remove your intake manifold for the crossover pipe? I've seen some videos where they just fished it through with the help of a borescope.
