Hi all
Do i need to remove the alternator before unbolting the manifold . i was told it will be £400 supply and fit to get it done but cant afford that so i got the part for £100 and will fit it myself . All help and advice will be much apreciated .

I have not done the 1.8 manifold on a Freelander but have done one on an MGF which is the same engine and you don't need to touch the alternator to remove the manifold.

No, as Manta says you wont need to go near it

Pics below of manifold on the early dizzy cap version, there may be some auxillary heat shields on your engine?

£400 = daylight robbery, fit it yourself, you'll need two new manifold gaskets

very straightforward, you may find that the studs will come out of the head because the nuts have heat stuck on them, it is best to get the nuts of in a vice so you can replace studs first in head before refitting, 2-3 hours tops

Hi, how did you get on with changing that manifold, i intend to change mine tomorrow and the Haynes manual says you need to move the alternator out the way and also remove the drivebelt (if it has air con) witch mine has. Is this a hard job me and my mate are on level 2 in vehicle maintenance and repair so want to fix it ourselves for experience aswell as saving money, any help/advice would be much appreciated thanks.

I've had mine off a few times and the Hayne's makes it way harder than it needs to be. No need to remove any belts! If memory serves the steps go thusly:

- Disconnect lambda sensory harness
- Jack the front up and put it on stands or use ramps
- Unbolt the front pipe from the manifold. You may need a new gasket.
- Unbolt the heat shielf if present
- Removed the long upper alternator bolt
- Slacken the lower alternator bolt and pivot it as far forward as poss
- Give the manifold nuts a squirt with penetrator oil just to be sure.
- Getting to all 5 is tricky but it's simpler if you use socket extensions and also have a normal spanner of the right size.
- Pull it all out .
- Rewnew the manifold gasket and make sure there is no trace of the old one AT ALL on the head or you will get blowing.

I think that's it, not more than a 20 min job .

Just wanted to add another step for making it easier.

After slackening off the lower alternator bolts and prying it away from the head. You can then remove the top altenator mount, just to give you more room and so you can see easier what your doing.

Just undo the 13mm and 10mm with a spanner. Then slide it off the stud (it will just fit off the end). Makes the job even easier imho.

Ah yes I knew I'd missed something, cheers for that Vissie !
