- In this video, I show you how I replaced the coolant expansion tank on my Vauxhall Mokka 1.4SE Turbo. Taking less than half an hour and using just a few simple tools, this will save you about £100 in garage fees.
What a brilliant video helped me alot I've ordered a new coolent tank as was on a 2 hours journey away from home and I've noticed my tank has a crack and steam is actually coming through this crack 😳🤣
Excellent video and tips - particularly about removing the body panel cover studs. Not great with cars but changed my split tank in 30 minutes.
Great video, really easy to follow. Done the job in less than half hour. Thank you.
Doing my wife's 1 tomorrow. Looks really easy.Thanks for the good video. 👍👊
Thanks, great video , really useful, I just replaced it , easy to do
GOOD VIDEO, VERY WELL EXPLAINED 👍
Very well presented
My Vauxhall dealer told me I have a leak on the tank and it will need replacing. I've looked at it and can't see or feel any damp and don't seem to be losing any coolant. They quoted £164 , they reduced it to £120 when I said it was too much. Think I'll do it myself as I've seen tanks for sale on the internet for about £20
I think this may be a common issue, as I have discovered many fractures in the underside of my tank, slowly losing coolant. I dont suppose you have a video on removing the rear spoiler to replace the washer jet???
Take the old one out, fit a new one. 👍
Nice video👍
If are losing water and theirs no water in the oil it’s the tank .I have changed three two on Astra’s and a insignia.very common vault
Hello is there not a sensor on bottom of these like the 1.4 astra of the same year
There wasn't a sensor on mine, perhaps it's dependent on the model variant.
My tank needs replacing and I'm getting ready to do it but now my mechanic has come to say i should remember to do the bleeding. I dont know what that is and he wouldn't say. None of the videos talks about bleeding. Is there anything like that or is my mechanic trying to make me bring it to him to do it and bill me bad as he likes to. I don't want his heart aching bill but still dont wanna spoil my car.
I must start by stressing that I am not a car mechanic, so I am giving this information in good faith based on my own "DIY" experience. Changing the expansion tank as shown in the video should not introduce any significant amount of air into the system. If any air does enter the hoses, it's usually possible to eject it back into the expansion tank with a couple of squeezes of the hose once reconnected. With the engine running, coolant is pumped around the system back into the expansion tank and my understading is that, as the expansion tank is at the highest point of the cooling system, any air should naturally find its way into the tank where it can be vented off by releasing the tank cap. There are videos on UA-cam showing how to bleed the cooling system which are little more than running the engine until the fan comes on and then, once cooled down, opening the expansion tank and topping up as necessary. Hope this helps.
Brilliant video, thank you!! Did you find any air pockets with your change? My coolant has gone down a little bit since doing the same as this video - does the air work it’s way out driving normally even with the cap on?
Thank you. The coolant will get pumped round the circuit whilst the engine is running, so I would expect any air to find its way into the expansion tank quite quickly. Make sure you top it up if needed.
Hi, great vid, very informative and useful, would this be classed as a complete coolant change? As mines needs done because the coolant is black lol.
Hi Dan,
No, to replace all the coolant you will need to drain the radiator, either by disconnecting the bottom hose or undoing the drain plug if the radiator has one.
It doesnt have a coolant level sensor?
No, mine didn't have a sensor
Great video! I have a question tho...I asked my mechanic if I could change it myself and he said the coolant system needs be pressurised or something ( I am not an expert so I don't know if this is a thing ) . It will cost me around £40 with new coolant . On your video it looks like I can easily do it myself . Did you have to do anything extra after the tank was replaced ? Thanks in advance
I'm no mechanic, but not aware that the cooling system needs to be pressurised. Perhaps they meant it should be pressure tested when the tank is changed? The cap contains an integral pressure relief valve to prevent too much pressure building up in the system when hot.
So would you suggest going to the mechanic or should I do it myself and it will be fine?
@@soton1989 I'm sure if you do it yourself, it will be fine, but to be honest, if a mechanic can replace the tank and the coolant for £40, you're probably unlikely to save much by doing it yourself.
Where did you buy the tank?
What is your reference?
Thanks
It was part number 95380033 from Leader Specialist Components
Is the crack visible and was you loosing alot of coolant
Yes, there was a definite crack on the underside of the tank, and it was losing a fair bit of coolant. It later transpired that I had a small leak in the radiator too so not sure how much loss was due to each.
Did you need to bleed the system after ? thanks
No, I didn't find it necessary. If a little air did get into the system, it would soon find its way into the tank.
@@Ap01101969 did you find any air got into your system when you did this? I did mine last week and my coolant has gone down a tiny bit since this
What tank have you used here?
It's a LSC 95380033 from Leader Specialist Components
Why did you have to change the tank please
The old one had a small crack in it
@@Ap01101969 thanks for letting me know and thanks for video 😀👍🏼
