Hello again!
Ok so I went to the garage to get some clarification, and there were more issues than I thought. Hopefully anyone here can give me some insight. So the leakage from the hose under the cooling tank was easy to fix, but there seem to be more leakages. See picture one for the leakage under the motor on the left side. They believe its the big hose going underneath the motor (which is the hard one to change). Check picture one for the hoses which are going underneath. The small one seem to be circulating fine since it was getting hot quite fast. We left the car on for about 10min (the motor got hot fast and the vent turned on pretty fast). The big tube on the other hand wasn’t getting hot and doesn’t seem to be circulating well. We also opened the cap to check for any airlocks but the agent was leaking from the cap fine. They think it’s still the thermostat not opening correctly which is causing this, which also caused the tube to break because of the pressure. The car is from 2002 but has only 20 000km, so it has been standing in the garage for a long time. They said that it wouldnt be an easy/fast job to check the parts and that’s why they gave the cost noted above. Does this sound like a valid analysis? Picture 1 : https://imgur.com/a/lpX8ZnA (I have marked the area where the cooling agent is accumulating). Picture 2 : https://imgur.com/a/OIICRmJ Thank you in advance for any respones!

Hello Simon!
Thanks again for the fast response. Yeah both of the big ones after 10 mins of running the car were getting just a tiny bit of warm, while the small ones were red hot. Sorry about the first photo, that's why I marked the area, it's very hard to see, but there is basically a pool of coolant just where the mark is. If you look very close at the dark area inside the yellow mark you can see a very vague white dot, that's basically a reflection of the coolant, that's the best I got. But they said that there is a leakage from the big hose going under there, and will have to open up everything to change it etc. Thanks for the ideas, if those are the possibilities then I'll probably have to go through and open it up to check. I was hoping it was something more simple. A question, so to get to the thermostat and check the flow of the hose and for leakages etc is a 2 day job on this car then? (sorry I really have no idea how complicated etc these things are). We negotiated a bit and they said they could do only the service for minimum 500€.

The large hose (second from the right, in between the small hoses) is the flow from the block via the curved pipe to the top of the radiator. If the major leak from the expansion tank has been repaired and the coolant level is correct then this large hose should be hot. The large hose on the far left hand side is the return from the bottom of the radiator via the oil cooler and bleed screw to the thermostat. When the thermostat opens this hose will also feel hot. All testing should be carried out with the cooling system refilled according to the MG Rover procedure which involves raising the expansion tank and using the bleed screw. Does your garage know about this? If not, it's highly likely that air locks have been introduced which could explain the cold hoses. You can find the procedure in detail by searching under my user name. Quote:

Hi Simon,
Thank you for the detailed explanation, I learned a lot! Quote:
I went through with the service, they will open it up and check everything. Will come back when I know more. Thanks! |
