I would hazard a guess at @ 2 hours labour. Took me a leisurely 3.5 hours to swap out an AC compressor on a TD6 (first time of doing it) but this was with an empty system so I didn't have to extract gas / do vacuum etc. That will come on top.

Best to get the tensioner and pulley checked over too.

My compressor seized, and shredded the belt. .

Hi Stanley,

Yep, my compressor appears to have the clutch permanently engaged too.
I initially thought this was a problem but I am not convinced now, as the later compressors on ours dont seem to have a magnetic clutch (I am unclear on this, so may be wrong until I can check properly).

It does get cold as I reported before (low pressure pipe behind top of rad), just not as cold as I expected.

A new OE compressor from LR is ~£1200
A new one from elsewhere is sub £300. By contrast the valve previously discussed is £120 from LR, or half that if bought elsewhere.

I havent had time to dig into this yet, but do intend to, so would be great to hear how you get on. Too many toys, not enough time
