Just thought I'd share my thermostat replacement experience...having read that it is a bastid of a job
Read up on this and other forums - and plan ahead.
Get a good supply ofthe right size jubilee clips
Battery out, battery tray out. No need to remove the EGR. Wash area down with petrol to have a clean working environment.
Break the factory jubilee clips by tapping a spike into the 'buckle' of the clips ( why they use these one-time clips is a mystery )
Remove all the rubber hoses carefully - this will reveal the two 13mm bolt heads that hold the unit to the engine. The top one is no problem at all, but the bottom one holds a bracket from the EGR pipework. You could spend a further two hours removing it all to pull it free - of simply bend the bracket out of the way
. You'll then need a long throw socket to remove the lower bolt, as it has a threaded shft coming off it.
That's it - reassemble in reverse.
Car now get's to temperature as it should - jobs a good'un
