Like mentioned sounds like thermo stat but def not the dalek cap.

Could be a waterpump?

Easy option is t-stat two bolts out bit of a wiggle old one out new one in. Refill and bleed a system holds 18 ltrs of coolant if you wish to drop all the coolant

Hopefully they will have been delivered when I get home, will be able to have a go tomorrow

There's 4 M6 x 12mm setscrews holds the t/stat top cover on, if you need to replace it get a Brickwerks stat. they also sell the housing parts.

I stated that you shouldn't be able to blow and suck through the 'Dalek' cap, this allows excess pressure out into the top-up tank and as the airtight system cools and pressure decreases coolant is drawn back until the header tank is full. If the cap has failed they can either fail open i.e. the system doesn't pressurise and the top up tank fills up or fail closed i.e. pressure builds and instead of being released it finds a weak part to blow out of (sometimes a hose or a sender O-ring or blowing a seal).

If a water pump is failing it usually seeps from the gland and drips from the underside, sometimes the bearings can be heard before the gland fails. In the past 6 years I've experienced both scenarios ... I'd wager this isn't what's wrong with your system.

Id be getting the radiator bled properly if it isn't before I did anything.
Do you get coolant coming out the top of the radiator when you open the bleed bolt?

Don't forget you need to rev the nuts off it.

would like a cap now to try it. At least i'll have cap and stat, hopefully when i get home. If not monday. Both are b'werks parts, should have come friday.
Just remembered friend removed the turbo today, to send off for a recon. So can't test anyway
Will probably fit both parts, while i'm waiting. The stat is in the waterpump assembly on a diesel isn't it.
Cheers for the replies by the way

Rev and bleed at the same time? Hmmmm.....i was reving then going around to the rad, i was getting no coolant or air. Will a faulty stat stop you being able to bleed? Or is it more likely me not bleeding and reving at same time

I bled mine by myself, getting it up to temp and with the bolt on the top of the rad loose. High revs helps. Once most of the air is out give it a good run around the block and then let out the last Bit of air.

Like this one with 2 holes it's a 1.6td Ian mate.

I've never done petrol engines in these have they hot four??

Stupid question time, where is the thermostat housing?
I've just had another go, and got the rad full of coolant and it still don't get hot. So must be the stat. So just need to know where it is
And the best place to drain it from

Look behind the alternator then down a bit so as you look at the engine
Locate alternator
Go below alternator
Look round the side of the engine and it has a large hose running to it

If you look at my link above mate you will find what to look for and quite possibly the worst engine location description ever

ok thanks mate
hopefully the stat will turn up soon

Before you change the stat, get the engine up to temp, put a brick on the accelerator so it revs to 2k and while it's revving like that bleed the system - being sure to top it up. There is a guide on here or BY on hoe to bleed. If I wasn't camping I woud have found it by now.

Ringo

ok.... REVVED THE NUTS OFF IT, and got it to work! excellant !
So thank you everyone for the input.

My mistake, when I met Llody he had a wbxer.

Good stuff - has this fixed the overheating issue now then Lloyd?
