the thermostat can be in one of 2 places (possibly depending on the cars age), either at the end of the thermostat housing, where the pipe from the radiator goes to the left side of the engine, this one is relatively easy to replace, to check if its this type you have just undo the jubilee clip holding the pipe onto the end of the thermostat housing, you should see it in the end if it is..
The other place, which is more likely, is behind the cam (timing) belt cover actually on the side of the block, meaning the cam (timing) belt and cover will all have to come off, and the bolts that hold the thermostat housing on are covered by the back piece of the cam cover.
when removing the cam (timing) belt, place marks at certain places before taking it off, tippex is good for this, then when rebuilding be sure to line up all of your marks otherwise the timing will be out and can damage your engine
9 times out of 10 on the later "phase 2" models (95-) it will be the 2nd type of thermostat and you will have to remove the timing (cam) belt and pulleys.
so when changing a thermostat it is usually good practise to also renew the timing belt and have a good check around the water pump to make sure the gasket isn't leaking
where is the thermostat
On my Vauxhall Astra 1.6 8v engine. The thermostat was on the left hand side of the engine behind the rear timing belt cover were the coolant hose leaves the engine to the radiator. hope this helps
Probably in a removable housing at the engine end of the upper radiator hose
where would i find the Thermostat on a Vauxhall Astra club 1600 8v saloon
To change the thermostat on a 2000 Vauxhall Astra Estate diesel, first ensure the engine is cool and disconnect the battery. Remove the engine cover if applicable, then drain the coolant and remove the hoses connected to the thermostat housing. Unbolt the thermostat housing, replace the old thermostat with a new one, and reassemble everything in reverse order, ensuring proper sealing and tightening of bolts. Finally, refill the coolant and check for leaks before starting the engine.

your thermostat is stuck you will find it at the end of the top rad hose where it meets the engine
It sounds like the thermostat is opening up late causing the engine to almost overheat before it opens. Replace the thermostat.
its behind the camshaft pully you have to remove the timing belt then the camshft pully to get to the thermostat and its housing bit of a nasty job really!!
The thermostat on a Vauxhall Astra 1.9 CDTi is typically located near the engine block, on the coolant outlet pipe. To access it, you may need to remove the engine cover and some components, such as the air intake or hoses. It's usually found at the junction where the upper radiator hose connects to the engine. Always consult the vehicle's service manual for specific instructions and diagrams.
behind the timing belt cover easy to fix
It is in the front
