Good to know, cheers mate it's approaching 150k now but engine is sweet so I'd like to get the best out of it if possible.

Has anyone used 10w 30 in their Td4? I got loads of mobil 1 10w 30 here but don't know if it's ok for this engine.

Yep I have OCD when it comes to checks haha. Sounds good you might have just persuaded me to give it a try.

H Yes it's just below max I check it daily just in case. I read a lot about r5 thermostat mod but don't know whether to trust it.

That would explain the sound I been hearing lol so it works great stuff cheers

Ha right ok yes I have one so is there a way I can check if it is working?

Thanks for reply. Where do I find auxiliary heaters to check?

My td4 heater only gets luke warm and not hot but temperature gauge sits bang on half way as it should could this be thermostat?
