Help with 3.0 litre capri

[DBSV8]

HI a few years ago my 3 litre capri was making a few rattling noises from around the engine bay

car has been laid up for twio years after a bit of tinkering with the carbs and a jump start managed to get her fired up , can anyone identify the graunching noises , happens after start up

its almost like the starter motor is engaging ?

much appreciated any advise .

Take the fan belt off & see if you still get the noise.
Don't run it for long!

ETA What happens if you press the clutch pedal?
If it's an auto is this the noise you had before - I wonder if the flex plate is damaged?

Fibre teeth on the timing gear ?, nice car BTW, had a couple of 3.0S's, MK3's though, my last one was signal amber, always loved the MK2.

right fan belt off and fired up no noise...its a manual and no issues with the gears

mind you i didnt run it long ....also discovered the fan itself has a lot of lateral play

Sounds like the alternator fan is catching on something - that isnt' the main noise but it shouldn't do it!

Is it just that the cooling fan is loose where it's fixed to the water pump or is there play in the pump bearings?

^^This.

Is it a bit tappety?

The viscous fan mechanism?

You say the fan has play ?
If it is all tightened up properly then the bearing on the water pump is shagged. They tend to make noise on start up until some heat runs through then they seem to balance themselves and go quiet.
Do not be fooled , get the pump out and replaced before it wrecks anything else .
Other grumbling from the front could be the timing gears beginning to fail , capri forums will offer the best cure for this . I seem to recall that uprated gears are the ultimate cure but they are not very cheap .

From your vids, I think your car has power steering and if so, that belt would have had to come off first.

The noise sounds like the power steering idler bearing being seized. Worth seeing if you can spin the idler by hand with the belt off.

Sounds a lot better.

I agree the fan on the front of the alternator sounds to be catching on something, probably best to remove & see if there are any obvious marks on it and the front of the alternator.

The fan shouldn't be wobbling about like that or making the noise.
When you turn it it looks as though the pump pulley is running true but the fan is loose.
Quick google suggests there is a viscous coupling https://www.tickover.co.uk/shop/contents/en-uk/d35...
I think yours is completely knackered & the main source of the graunching.
A worry is that if it lets go completely when running it could throw the fan into the rad & take the rad with it.

thanks , i just googled tickover , i'll take both the alternator and viscous fan off tomorrow and check to see if it needs replacing , there was a spare alternator that came with the car , this one looks pretty new ? but ill check it out

cheers

The more googling I do the more I think the water pump is the item below the alternator & TBH I'm not sure what the pulley with the loose fan actually drives or is mounted on.*
I had an Essex engine Scimitar but it was a long time ago & I don't have any manuals.

ETA *An idler of some sort in the front of the timing cover? https://www.ebay.co.uk/itm/Ford-Essex-V6-3-0-FRONT...

Thanks.
It was pics of new water pumps that set me wondering.
