Detroit Diesel — Exhaust Manifold Installation
Repair & overhaul
From a Detroit Diesel service manual — check it applies to your exact model before use.
Before you start
- Make sure that each gasket is properly aligned before tightening the mounting bolts on that exhaust port.
- Diesel engine exhaust and some of its constituents are known to the State of California to cause cancer, birth defects, and other reproductive harm.
- Always start and operate an engine in a well ventilated area.
- If operating an engine in an enclosed area, vent the exhaust to the outside.
- Do not modify or tamper with the exhaust system or emission control system.
Procedure
- Install a gasket on each exhaust port. Fasten the gasket by installing one mounting bolt on the forward side of each exhaust port.
- Position the exhaust manifold next to the heads and slide the manifold to the right until it rests on the bolts.
- Line up each gasket and install the remaining bolt and spacer on each exhaust port.
- Tighten each of the mounting bolts to 50 N·m (37 lb·ft).
- Install the turbocharger on the mounting studs on the exhaust manifold. Refer to section 6.3.3.
- Connect the batteries and lower the hood.
