Hi chaps,
A bit off the LR topic but I thought someone on here would be able to advise.
Been checking a 95 Ford Fiesta 1.3 for a friend. Test drove it and all was well until I got back to base. After switching off, I opened the bonnet to check all was well and discovered that the coolant was boiling in the head and pushing coolant back into the expansion tank, through the breather hose from the top of the thermostat housing that connects to the expansion tank. Thinking "Thermostat" I then checked the rad was hot and discovered it most certainly was.
This doesn't seem right to me but I've not worked on these engines before. The coolant temperature gauge was showing a reasonable level and was stable. Obviously the next steps would be to test the thermostat and back flush the rad. Before I do, whats the thoughts about this problem, if it is a problem?
Many thanks,
Dave
