Not that i could tell, although we had to replace the radiator about 2 months back as it was leaking, so we did that, then the radiator bottle as it had a leak discovered once the radiator was replaced. We then replaced the thermostat thinking that may have been an issue (the old one fell apart when removed) but apparently it's still no good.
I'm about to head down to the mechanic and have a chat with them about what's happening.
Not sure on the test sorry @timbo
