SDV6 - Thermostat replacement - Help

Hi Guys,

I have purchased a complete Discovery 4 Coolant Thermostat AH22-8K515-AA and now need to replace my current one as Step 1 in solving my bouncing temp gauge...

Has anyone replaced theirs? The guides I find are for the 2.7 TDV6 and I don't have the Workshop manual for the 3.0 SDV6 Sad

I replaced the thermostat within the plastic housing on mine successfully. Fiddly to get all the hose clamps undone.

I was doing it as part of a fluid flush, so be aware you’ll lose all your coolant.
My only advice would be to invest in a proper hose clamp tool on a cable. I spent forever trying to get my various pliers in to undo all the hose clamps. Would have been so much easier with a proper tool.

Yeah I am aware of that and I think driving through all the hot places we drive through, new coolant wont hurt Smile

Noted on the clamp tool, will see if I can find anything.
