Good afternoon Guy and Gals, My wife loves her RCZ its fast and stylish, its developed a problem often discussed on here loosing coolant but nothing evident.

Recently the 'Top up coolant' warning has been on more than its been off and has got worse over the last week, I rarely drive it so I filled the reservoir up to the max and did 20 mile test drive, it used about 500mls so action needed.

I found a damp patch at the rear of the engine and from previous posts on here the thermostat appears the culprit and is in the right area, on stripping the car I found that the lowest and rear facing pipe was wet so ive found the problem, I have the thermostat unbolted the only thing stopping it being removed is its connection to the pipe that runs around the rear of the engine, the workshop manual says undo the connection oh very useful when you cant see what you are doing, I have lifted the metal retaining spring but can not withdraw the thermostat, one end of the metal spring is loose while the the other end is still attached.

I have used a reasonable amount of force on it already and its still refusing to detach itself from the pipe at the rear of the engine, its very difficult to see what the problem is.

Couple of questions is the metal spring what joins the thermostat to the rear engine pipe or something else, should one of the end have come loose while the other is still connected.......should both have come loose or none.

Will a reputable pattern part be suitable or is it advisable to get a Peugeot thermostat bit like with sensors. Any advice will be appreciated.......... well almost.

Thanks all, take care Bob

The pipe slides into a housing held in by a spring loaded clip (horseshoe shape) which goes into a slot in the housing at the rear of the engine you have to pull this clip out to release the pipe connection its fiddly & a pain to get at but I used long nosed pliers but be careful you don't drop it down the back as I would think it is a dealer part only then once released you can remove the thermostat tank refitting is a lot easier because you will know the position/angle the clip goes back into the slot once you get the spring just nudging the slot it just slides back into position
As for the Parts they are on ebay that's where I got mine & that was an original Peugeot Thermostat Tank for a 200GT

Thanks Pedro you are a star, I wasn't sure if I had to fully remove the metal clip, now I know I will hopefully be able to remove it, I didn't want to break the pipe the thermostat end fits into as that would be a nightmare to replace running behind the rear of the engine.

Take care all Bob
