Important note - this is a 1.6 engine. maybe someone else will miss this important detail... for a 1.4 the part looks a lot different, albeit it is in the same position. it is also easier to get to, than this one. thanks for the video, i'm really loving this series.

If you are struggling with the back pipe, heres how i did it; I first disconnected the other pipes, battery and electric connections of the thermostat. Spray some oil on the difficult connection hose and wiggle with the housing so the oil spreads. Then i used a strap rope with hooks and put it under tension ( i hooked it up at the hose connection point that goes to the air heater) and i got the hooks locked on the front chassis. Put it under tension, then get a crowbar and use that on the front side of the thermostate housing. Build up the tension and you will get it out, hopefully. Good luck

Hi, looking at this video one could imagine it looks very simple but for having changed the thermostat on 2 Peugeot 308, 1.6 VTI 120hp (2011), I can tell you that it is much more difficult than shown in the video. The access is relatively restricted and especially putting the locking clip on the water pipe (the one connecting the thermostat to the water pipe at the backside of the engine) is very tricky and may need 2mins or several hours ! And I consider myself not as a beginner as maintaining all my cars for some 45 years now... The designers of his engine should be ashamed for having created such non reliable parts. Even worse, the replacement parts might not be much more reliable and might leak again after a couple of years !

Thanks very much for this tutorial it’s excellent. One question I had is how on earth can the clip at the back be put back on due to limited space. The best solution I can come up with is using 2 pairs of 45 degree bent needle nose pliers then feed the clip up with 1 pair and attempt to lower it using both pairs. Looks a horrific job though as I cant even get my fingers in. Do you guys have any further ideas how this can be done?? Thanks.

Informative and easy to follow

Thanks so much for sharing. My AC is not cold all the sudden and the fan is on all the time and temperature gauge is high eventhough engine is only warm.

Hi, I have a couple of questions. Is the engine running when you bleed the thermostat housing? Is the lid supposed to be off of the coolant overflow? He puts the lid on, but it looks like it's off when the bleed is happening.

I had a leak on Peugeot 308 1.4 70kw from 2008. It was caused by cracked thermostat housing. Thermostat housing seems to be manufactured from two parts connected together, so it was leaking in the point of connection of one part to second. I found the leak by pressurizing system by drilling hole into reservoir cap and inserting/glueing in valve from bicycle inner tube. Then pressurizing to 1-2 bars (pay attention here not to destroy something with overpressurizing) When choosing replacement pay attention to number of thermostat inputs/outputs. Basically there should be one input and one output for front cooler. One input and output for cabin cooler. One hose to engine. And if the car has intercooler for turbo or for cooling something else, then there is additional input/output.

I am doing a thermostat and timing chain on a 2011 Mini Cooper, it’s neat to see and compare

Excellent video. Thankyou 👍🏽

Reading the Haynes manual it says I need to remove the thermostat to flush the engine coolant. Watching this video, I’m not keen. Can it be done without?

What is the total working time for this repair?

Just about to do one on my sister in laws 2014 308, for my particular model it had only one 4 wire plug, and the replacement had two separate plugs, but it turns out there is a wiring loom update so now im in business.

This Guy is Obviously a Professional so their is no need to Scrap The Car after this Job....!🤑😂😇

Have you got a video for the coolant pipe that runs along the back of the engine off the water pump

if you also remove the battery box, you have a little more space

Exelente

Hi..I just finish removing the thermostat housing now but there is a slight difference between the old and the new part I bought. There is one extra pipe on the new part. Is it still going to work or water will escape from the extra pipe opening?

I've had mine recently replaced but the problem still occurs the leak could actually be worse now it can take around a week to 2 weeks to go below minimum while before replacing would usually take around 2/4 months what would you recommend.

Its a hell of a job to get that hose in behind the engine

can you tell me if it is possible to change a broke water pump hose without taking out the full engine?

Good 👍👍👍

porque se gira el tornillo negro al final y baja el agua del deposito de refrigerante?

Nice one, thanks

Hello, I'm have peugeot 207 1.4 2006, and have 95-100 C in towen when drive. I's ok this temperatur?

Undoing the screw at the end was that to bleed the system? I didn't see that step.

I swear manufacturers must design things in such a way as to maximise the labour charge when they inevitably need replaced!

Hi trying to change my thermostat and it's stuck at the pin connection to the engine bay, any tips to get it to release

Will this be the same process for the Citroen DS3 1.6thp?

wow did the owner regularly drive through the sahara?

How many time it took please? Thank you

Was the engine running when bleeding it ?

I have the turbo 207 and the temperature gauge sits at maximum gauge temperature when the engine is cold . And the thermo fan wont turn on at all , I'm guessing that this multiple sensor thermostat is my issue.

What we're the reasons for changing it

Great video, autodoc, you need to specify the engine type, it looks like a TU engine, it is different on others 207 engines

If you make a video whith a diesel engine will be more useful
