Coolant Leak Ibiza Cupra Bocanegra

Sep 12, 2019
Hey all, recently purchased an Ibiza Cupra Bocanegra 2011 plate with 52k miles. Had nothing but trouble with it unfortunately. Drove it back 120 miles and 100 miles in coolant light came on, white steam emits near the gearbox area on passenger side after a good drive in it and a hissing as if some coolant is dripping onto a hot metal part, checked it and it was way below minimum. Took it to garage next day as obviously I suspected a coolant leak. They replaced the thermostat, drove 20 miles back to mine and 20 miles later, coolant leaking. My car is puddling all the time.

Took it back to the garage, they replaced some hoses and seals. STILL leaking. Just been to Evans Halshaw Seat Harrogate and they did a pressure check and nothing came back. I am absolutely lost and don't know what to do. I think it's a head gasket.

Any help would be highly appreciated. Thank you.


I only wanted a remap

If it's still under warranty, unfortunately looks like it's going to have to keep going back till they fix it. I assume they will have checked for eg oil in coolant and coolant in oil which would be the signs of an internal head gasket leak. An external headgasket leak is where it runs out eg the back of the engine and drips down. If you are able to safely jack up the car and support it, it's fairly easy to see where coolant has been because it stains the metal pinky/orange.

When my headgasket went, looking under the car looked like this:


Away washing the car
Pretty sure the water pumps are prone for failure on most of the Ibiza range too, check to see if there is any leaks around it, and also check with the engine running so the water is being circulated through

It's off back in tomorrow for another pressure test as they wanted me to steam clean my engine bay as there was so much coolant everywhere
