MAN 65903100000 Drain Plug

Description

This drain plug is a critical service part used in fluid systems to seal the drain opening and prevent leakage. It is commonly found in engine oil pans, transmissions, and cooling systems. Manufactured by MAN with MPN 65903100000, this plug ensures a secure and reliable seal, contributing to optimal system performance and longevity. It measures 21 x 21 x 30 mm and is proudly made in Germany.

Key Features & Benefits

Basically, it seals the oil pan. That’s it. It’s a threaded plug that screws right into the bottom of your oil pan, holding all your engine oil in. Sometimes they have a crush washer with them – that’s a little soft ring that helps make a really tight seal. Think of it like the stopper in a bathtub. Without it, all the oil would just pour out. It's located on the very bottom of your engine’s oil pan. When you go to change your oil, you remove this plug to let the old oil drain out, then you put a new one – or the original, if it's in good shape – back in to hold the fresh oil.

Symptoms, Risks & Replacements

Well, without it, your engine would quickly lose all its oil. That's bad news – really bad. The oil keeps everything lubricated, prevents wear, and helps cool the engine. Losing oil leads to major engine damage, and that’s an expensive fix. It’s a small part, but it acts like a shield protecting your engine from catastrophic failure. You’ll notice if it’s leaking; usually, you'll see oil spots where you park, or you might smell burning oil. You can find these pretty easily, even online at places like Fixparts Online, and they're relatively cheap to replace – much cheaper than an engine rebuild!
