1998 with 2.8L 5V. Can anyone tell me or point me to a link that shows the location of the secondary air pipe. My dealer says mine is cracked and leading to a CEL.

OK found the pump and flexible tube from the pump to the steel/al? tube going under the manifold to the combi valves. The pumps runs for a couple minutes on start up, then stops as expected. The flexible tube warms up. I cannot see or feel any leaks in the flexible tube. Could the crack be in the fixed tube going to the combi valves? The dealer quoted a price of about $117 for the tube but didn't tell me which one?

Any thoughts?

I'd love to great rid of this CEL

Thanks

 

Bob,

The secondary air pump tube also gets clogged. Maybe that is what he is talking about. In any case, $117 isn't too bad of a price. The job can be a PITA but, if you are very patient, it isn't too hard.

The metal tube under the manifold looks pretty difficult to change without removing the manifold. From the pieces I can see (only a small section though) it looks fine.

The plastic corrugated hose from the pump to the metal hose looks OK but you say gets plugged? I bet the $117 the dealer quoted for the tube was that piece, based on what they wanted for a similar plastic tube connecting the two camshaft covers.

Can I pull the plastic hose and apart and if it cracks, which it might, can I replace with a piece of rubber hose with clamps at either end?

Thanks

Bob
