Hi, I have been lucky enough to get hold of a nice CX5 2013 my sister had it from brand new, car religiously serviced, but she did manage to run into having the head go and was fixed under warranty by Mazda, But it has started overheating again, well it goes into limp mode and I stop straight away, the radiator has fluid and I have made sure to top it off daily at this stage to confirm that, but I have noticed the coolant bottle goes from the full mark, to filling the section above that when I stop to check?? It’s not cycling back to radiator? Have had a mechanic pressure test, no leak?? Would love to hear any advice or ideas on this situation, Cheers

 

What engine? I’m confused, do you need to add coolant every day? But the coolant bottle goes from full to over-full? What does the temp gauge say when it goes into limp mode? Has the thermostat been tested?

 

Hi it’s the Diesel engine and when I say top it off, I’m simply checking that the radiator is full, I’ve had it 2 days, the hoses are all firm when it comes up to temp,
