I've just gone to replace our expansion bottle as the garage told me it's causing my coolant to leak and theres no sensor in mine the bit is there to attatch it and the hole where it goes up but no sensor to be seen should i be worried at all?
My fan comes on as soon as I turn on my engine, also the EML light is on as a result. Could this be a faulty temp sensor? The car is using normal coolant and not running hot. But I noticed it’s using slightly more fuel aswell as.
@@S55M3 yes the garage could see that I had a crack in my thermostat housing and would only show when engine running hot. £138 for new replacement and now the car runs great. Touch wood 🪵 😃
Thanks for the video. I see error 4 and the temperatura gauge doesn’t move at all. Do you think this sensor could be the issue? Or the engine temp sensor?
i have an astra h from 2005 and i don t have this sensor, but i have the hole to put it, some help, i bought the car last week and i have overheating problems
I have changed sensor, fluid, cleaned the fluid tank, repaired small leak of fluid... But the coolant level warning is still being thrown at me. Any suggestion for possible solution?
I have been trying to test the sensor to try and find out how it actually works so i can get a better understanding of the system, I am an auto sparky and have a 2002 TS Astra, my level sensor warning comes on and I have changed the sensor today. Someone below in another comment said that there might be a metal float inside the bottle that goes around the sensor hole, if this is the case the float might be stuck or something, I will investigate further. Have you found your issue?
I have same problem. Did you solved it? I changed sensor, changed cooler fluid, cleaned the fluid tank, repaired small leak of fluid... But the coolant level warning is still being thrown at me.
@@electricwhirl5175 Hi, changing coolant tank helped in the end. It was probably too messy inside and floater was getting stuck or something like that.
@@JohnhadebeMthimkhulu-cl5gc It might. If it is because dirty tank, you may first try to dismantle it and clean it with and some cleaning chemical from inside. But in my case it did not helped in the end.
