Inspect the related cover, gasket, O-ring, anode, and sealing surfaces while the assembly is apart. Tighten according to the Volvo Penta service procedure for the specific engine and avoid over-tightening small heat exchanger hardware.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eAlternate\/Superseded Part Numbers\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e3858994\u003c\/li\u003e\n\u003cli\u003eVolvo Penta 3858994\u003c\/li\u003e\n\u003cli\u003eVP3858994\u003c\/li\u003e\n\u003cli\u003eVOLVO-3858994\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eParts Desk Insight\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThis screw is usually tied to heat exchanger service, so it is worth checking the cover, gasket, O-ring, and anode at the same time.
