1664300 Intermediate Pipe | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta intermediate pipe is a formed charge-air transfer component used in the induction-manifold and intercooler intermediate pipe. It is manufactured to the original Volvo dimensional, material and interface requirements so the serviced assembly retains its designed alignment, sealing, load capacity and operating reliability. In service, it transfers intake or charge air between the intercooler and induction manifold while maintaining the specified flow path. Selection must be confirmed by OEM part number 1664300, the exact engine/product model, serial number and the installed assembly configuration.

🔌 Function

The intermediate pipe carries engine coolant between sections of the cooling circuit, completing the flow path between connected components. Maintaining a sealed, unobstructed passage here is essential for stable engine operating temperature.

⚠️ Common Signs of Failure

• Visible coolant weeping or dripping at the pipe joints or connections
• External corrosion, pitting or scaling that thins the pipe wall
• Cracks or splits causing coolant loss and pressure drop in the cooling circuit
• Rising engine operating temperature or repeated coolant top-ups
• Internal deposit build-up restricting coolant flow through the pipe

🛠️ Service Notes

• Clean both joint faces and the pipe bore, and fit new gaskets, seals or O-rings rather than reusing the old ones
• Check the pipe for corrosion, cracking, chafe marks and thinning, especially at clamps, bends and bracket points
• Offer the pipe up and start all fasteners before tightening any, so it is not pulled into strain between the two components it joins
• Tighten evenly to the figures and sequence in the workshop manual for your engine, and refit every bracket and support
• Check clearance from moving parts and hot surfaces, then check the joints once the system is up to working temperature and pressure
