What is crossover pipe?
We’re talking about the exhaust crossover pipe that routes hot exhaust gases from the front cylinder bank of a transverse V6 or V8 to the rear cylinder bank. It travels from the front manifold above the transaxle to the rear manifold, where it connects to the rest of the exhaust system.
What does an H-pipe do for exhaust?
An X-Pipe or an exhaust H-Pipe are at the heart of a performance system and bolted in the center of the car. Also known as a crossover pipe, each system works by balancing the exhaust pulses from either side—or cylinder bank of a V-style engine. The result is a smooth exhaust flow and a more efficient engine.
How do you replace an exhaust crossover pipe?
1] Hidden under all that stuff is the old, leaking crossover pipe. We removed the air cleaner and battery to improve access. 2] First, soak all the hardware in penetrating oil, preferably for a few hours. 3] This bolt on the rear manifold proved tough to turn.
Can a washing machine cause a plumbing crossover?
If the washing machine runs appropriately and the mixing valve is not causing any issues, check every faucet that has the single handle, by touching the pipes that run to that tap. If the pipes of one fixture are both cold than that faucet is the cause of the plumbing crossover and must be fixed.
Why does my water heater and plumbing crossover?
If the pipes of one fixture are both cold than that faucet is the cause of the plumbing crossover and must be fixed. Plumbing crossover is mostly unpleasant during the shower, hand and face washing, but having the water lukewarm when we need it hot, especially when washing the dishes, could lead to unsanitary conditions and health risk.
What does crossover mean in a plumbing system?
Plumbing crossover is a situation when water flows into the hot water system where it mixes with hot water, and once diluted, it provides lukewarm water.

How can I replace my Origi NAL crossover pipe?
1. A problematic bracket that supported the middle of the origi-nal crossover pipe has been eliminated. (Ours had already failed at a welded joint.) 2. The flexible metal bellows have been improved by switching from a multipart crimped design to more robust, one-piece swaged bellows.
Why does my check engine light come on after a failed crossover?
Fuel economy also can suffer: Your Check Engine light may come on because the oxygen sensor downstream of the exhaust leak is picking up extra O2, forcing the engine computer to order more fuel from the injectors. Fortunately, replacing a failed crossover doesn’t have to be a job for the shop.
Where is the exhaust pipe in a minivan?
You can see the trail of black exhaust gases in the photo on page 141. That seemingly small leak made our minivan sound more like a garbage truck. Because of its location high up in the hot engine bay, away from moisture and road salt, the exhaust crossover pipe leads a pretty good life.
