21523136 Inlet Manifold | Genuine Volvo Penta Part

🔧 Product Description

Cast intake manifold used on the 7-litre TAD generator-engine family. It receives cooled compressed air from the charge-air system and distributes it to the cylinder-head inlet ports. The manifold also carries the original heater, flange, studs, gaskets and connector locations required by the factory intake arrangement.

🚤 Compatibility

Typically suits:

• Volvo Penta TAD752GE
• Volvo Penta TAD753GE
• Volvo Penta TAD754GE

• Engine Family: TAD

⚙️ Key Features

• Genuine Volvo Penta intake-system casting
• Designed for the TAD752GE-TAD754GE charge-air and inlet layout
• Uses inlet gasket 20794356 and associated gasket 20531832 where specified
• Accepts original heater 20758403 and flange 20585825
• Maintains correct runner volume, sealing and component alignment
• Engine type: Inline-six turbocharged and charge-air-cooled generator diesel

🔌 Function

Receives cooled boost air and distributes it evenly to the engine inlet ports while providing mounting points for the intake heater and associated fittings.

⚠️ Common Signs of Failure

• Boost-air leakage at the manifold gasket
• Black smoke or reduced output under load
• Hissing noise around the manifold
• Cracked casting or damaged flange face
• Loose studs, stripped threads or corrosion around fittings

🛠️ Service Notes

• Blank the open ports as soon as the manifold is off, so nothing can drop into a cylinder or the head while it is away
• Clean both mating faces without scoring them, check the manifold for flatness, cracks and corrosion, and fit new gaskets and seals throughout
• Clean out oil, soot and carbon deposits from the manifold interior before refitting, and look at the crankcase breather arrangement if the build-up is heavy — refitting a fouled manifold puts the restriction straight back
• Tighten the fasteners evenly, working outwards from the centre in stages to the figures given in the workshop manual for your engine
• Refit and check all charge air, breather and sensor connections and their clips; an air leak on a pressure-charged inlet shows up as lost power and smoke rather than an audible leak
