bis thermostat

[126redbomb]

Happy New Year to all. 
I want to change the thermostat on my bis but I need to know if it only come as a complete unit or can I buy just thermostat. I think mine hasnt been changed for quite sometime and Im not to sure if its working properly ( it could have a blockage).  Does anyone know where to buy one from.

Cheers for that.
 I think I need to test the thermostat and probably do a compression test.  I just hope the head gasket hasn't gone.

Most Bis owners remove the thermostat completely, the thermostat can cause problems due to poor design, that's what I have been told.

Take it out before is sticks and ends up making tea

I recently bought a thermostat and housing off of the internet for about twelve quid all in. needed a small bit of filing to make it fit as the shoulders holding the thermostat in place were a bit too proud, fine otherwise.

I've been looking everywhere on the net and 40+ quid is the best I can find, so £12 is WOW.  This might sound really thick but what do I need to do to plug the hole of the thermostat.

Ebay, will try to find where, the box is still about somewhere. It is a complete unit, think you would have to
break the thermostat to remove it from the housing (not 100 percent on this).
Not sure why or which hole you want to block

Sorry about the hole! It was late last night when I asked the question, after doing nights and having no sleep from the thursday my head was in a fog.
 So I just have to pull the old thermo out of the housing?
Thanks for having a look for the box H n M, if you can get back to me that would be great.

There has been a lot of debate regarding to retain or remove the thermostat. I have kept mine. As long as the cooling system is regularly maintained, the current set up should be fine. If it takes a while for the engine to warm-up, then the thermostat needs looking at.

The thermostat allows the engine to warm-up quickly reaching its operating temp before allowing the coolant to flow through. By letting the engine warm up as quickly as possible, the thermostat reduces engine wear, deposits and emissions.

On average a BIS does like 30000 miles before dying in a cloud of steam.

Get rid of the thermostat, you have been warned
