I have an intermittant coolant leak. It appears to be coming from just above the oil filter. It doesn't happen all the time, it can be fine for a few days and then suddenly for no reason it's a drip drip drip.

At first I thought it was the water pump, but I changed this on Saturday past. Now I think it may be the hose that comes out from the block horizontally towards the right.

Is there an easy way to get to this connection which I believe contains a gasket or is it a manifold off job ? How easy is it for a novice to remove and rplace the manifold ?
Can I just drop it down, do the work and then lift it back up or is it more complicated ?

Cheers

that pipe is an interference fit, secured by a single bolt on the other of the pipe into the block.

it has an O ring in there to seal it.

if you drain the cooling system, remove the rubber hose off the end of it, remove that single bolt, you *should* be able to pull the pipe out. You will need a hammer and suitable lump of wood to put it back in (don't hit the pipe with the hammer!)

i'm not sure if you can do it with the exhaust manifold in place, i have never tried. but removing the manifold is an easy job, so if it is in the way - just unbolt it. might want to spray the nuts with a good penetrating oil (not WD40) every day for a few days before you do the job to make removing them a bit easier.

you can if you wish, replace the pipe with a new one from FIAT. it has been revised and now has 3 sealing O rings to help prevent leaks. ~£25 tho, it's up to you!
 
If you can get it out, and can get a replacement o ring, clean engine and pipe as well as you can & use lots of Fairy liquid on end of pipe and try and push it in by hand.

Please tell us if you succeed, without taking the manifold off.
 
Just out of interest, where else could possibly leak near the oil filter. As I said it isn't a constant drip just does it occasionally.
