Alternator cover needed?

Oct 31, 2005 7 Replies

My none-too-careful mechanic replaced the alternator on my Rover Metro 96. The old one had a plastic protective plate.



I've never seen one of these on an alternator before, but for some reason Rover thought it necessary.



The mechanic said it didn't fit the new alternator, but I'm pretty sure they were exactly the same. I think perhaps he forgot to put it back. He said it wasn't needed anyway.



Is it necessary?



Has anyone replaced a Rover Metro alternator and found this plate doesn't fit on the replacement?



Any help appreciated.



Thanks

I think you will find it will fit after you've changed over the long studs that it secures to from the old alternator, I cant remember but is it a metal one ? if so it sits close to the exhaust, thus protecting it from excessive heat.

Its plastic, so perhaps not used for heat protection.

Any ideas?

Thanks

But not necessarily for long.

I've cooked at least one alternator on a 2cv by leaving the "belt cover" (which is actually cooling ducting) off.

I *know* it was cooked, because there was smoke coming out of it...

Some alternators had a cover with a duct attached to direct air for cooling, but even if this is the case they're not necessary. Don't worry about it, the alternator will work fine without it.

Are the 2cv air-cooled. Maybe something to do with it, if the alternator depends on the engine cooling fan. If the alternator has it's own cooling fan which 99.9% do, then no problem.

Change mechanic?

No. Don't worry about it.

Yes I will!

Well this is just a simple plastic cover, doesn't have a duct on it.

Its very thick plastic that I guess goes over the alternator to protect it from something. Its hard enough to be like metal.

Do you think this matters?

The mechanic says no, but then if it doesn't then why did Rover put it on?
