Is This The Death Of My Cossie

[slbtaz]

I have a 2.3 16v 1986 and have a problem as the fan has now stopped spinning quickly and rotates very slowly engine still starts,i'm worried as i was told that the fan runs on oil pressure does anyone kno whats wrong please help

I doubt the fan runs on engine oil pressure. More likely it has a 'viscous clutch'. The one on my Viva was 2 bits of metal and a bit of cork in the middle. Your cossie one may have oil instead but it won't be engine oil.
Try the 'carrott test' and poss you need a new viscous clutch for it. Shouldn't be too expensive for a new one.
Do keep an eye on the engine temp until its fixed, especially in this weather or it could become a self fulfilling prophecy!.

As Berksie has said, it doesn't run on engine oil pressure, it has a viscous coupling which transfers more torque the hotter it gets.

Does it speed up when the engine is up to temperature?

 

[slbtaz]

The fan doesn't speed up the hotter it gets just stays gently turning any ideas on what the problem could be nice to kno she is going to be ok

You need a new visco coupling mate. I think GSF and ECP do them, or try your dealer armed with your chassis number.

cheers mate your a star,you wouldnt happen to kno where i could get a 2.5 16v engine from aswell ive bought a f reg 2.5 16v without a engine as bodywork is lovely and the person who i bought it from was going to break it for spares,and i couldnt see it go to waste like that

Good luck finding a 2.5 16v for a decent price, you could always do a 3.0 24v Conversion

I was thinking about rebuilding the 2.3 engine and putting it in the 2.5 as the 2.3 is starting to rot in all the usal places, 3.0 24v would it fit?

 

[Ady1983]

Easy , I have seen a few its alot of work though, I have just fitted a 3.0 24v in my 300CE

 

[slbtaz]

sounds like to much hard work to me looks like the 2.3 16v will have to be the donor engine for now

 

[Ady1983]

seriously the hardest bit is the loom work I think, don't forget they did do a 6 cylinder 190 so the engine should drop straight in...

 

[slbtaz]

where can i find a loom and 2.6 6cyl engine any ideas?

where can i find a loom and 2.6 6cyl engine any ideas?

I think someone on here was breaking a 260E recently

 

[slbtaz]

i'll have a look arround here would it be worth fitting a 2.6 in the mercedes though or do you think i should just keep trying to find a a 2.5 16v engine?
