Dagnabbit!
After it seems my crankshaft seal is broken and I need to replace that it now seems my thermostat is broken too..
My engine temp was below half all summer but I thought that was normal (?) Now its getting freezing here in the Netherlands and now my temp wont go up at all.
What is a normal temp for a 2.5 CRD?
And any tips and tricks to replacing the thermostat?
See my attachment, that was the temp after a 45 minute drive....

 

Your question, "And any tips and tricks to replacing the thermostat"?
See my easy mod. on the matter, saves a lot of money and time.
The temp. in your picture is defo wrong. Your 'stat. will be jammed open, although it does take longer for a diesel to warm up in winter. Also see my mods various for speedier warmup.

Where can I find that?

 

BTW the Aux heater under the car is not working either... I hoped it would start working since I connected the fuel line to the heater again and reset the car Computer (by disconnecting the battery) but not working it seems..

 

"Fitting a second thermostat" -- is the mod. Cost abt. £5 to £10 for the 'stat. Asearch should find it.

That is a very, very nice idea Mr. Leedsman! ..
I definitely gonna try that.

Ok I'm about to collect my new Renault 5 thermostat..
But still not completely sure which side should point to the engine?
And where exactly to drill the 1.5mm hole?

 

I studied my new thermostat and I think the direction and the hole should be like I put in the following picture:
if not, please enlighten me

 

Yes you have it right, the wax pellet always goes to the engine. Where your little drilled pressure hole goes is wherever you can drill it safely, I put mine right though the rolled lip - see here.
