Do you mean one of these? If so then NO. It's a new one required. They are about £15

Cheers Ratty your a star. !!!
i asked because a mechanic said "rip out the thermo and run it without it", and i couldnt see how it was supposed to open.
Many thanks. will get one

Don't rip the thermo out. There's no point. The centre pipe is a traditional temp type valve. The pipe that comes out on an angle is a bypass valve that is sucked open by your waterpump when your engine reaches upwards of 1500rpm. This means that when on tickover in winter your heaters stay warmer and when booting it hard the coolant has a clear path. it's the best of both worlds.;)

let me see if ive got this right, the thermo is upside down inside the housing ?? hot water pulls it back,instead of the way the old thermo's used to push it down ??
well, i've had it off errrr if you know what i mean, and cleaned it,,,,errr,,, where's this going,??? now i've lost my train of thought ...where was i ???? oh yes.
Its works after getting really hot from the top hose. "oh forget it ".
Confused.:confused:

It's good int it. It confused the living hell outta me to start with. This is how it's explained to thems with a technical head on em...... (this extract is for a TD5 engine but it's the same stat).


The thermostat is used to maintain the coolant at the optimum temperature for efficient combustion and to aid engine
warm-up. The thermostat is closed at temperatures below approximately 82°C (179°F). When the coolant
temperature reaches approximately 82°C the thermostat starts to open and is fully open at approximately 96°C
(204°F). In this condition the full flow of coolant is directed through the radiator.
The thermostat is exposed to 90% hot coolant from the engine on one side and 10% cold coolant returning from the
radiator bottom hose on the other side.
Hot coolant from the engine passes from the by-pass pipe through four sensing holes in the flow valve into a tube
surrounding 90% of the thermostat sensitive area. Cold coolant returning from the radiator, cooled by the ambient air,
conducts through 10% of the thermostat sensitive area.
In cold ambient temperatures, the engine temperature is raised approximately 10°C (50°F) to compensate for the heat
loss of 10% exposure to the cold coolant returning from the radiator bottom hose.
