I've followed the question from m4rkw and the feedback from NemesisUK, ColinBarber & rich1068. I have a Lexus RX 300 SE, 2005 LPG which is also overheating. I have broken down four times in approximately 12 months. I've parked her up with the expectation of replacing the engine due to a suspected head gasket, which I've been advised would require a replacement engine as the garage I use wouldn't bother replacing or skimming the engine head and new parts etc. Anyway, I've ordered the pink coolant today, to monitor where the leaks are coming from with a view to saving my car as it is incredibly reliable and efficient, but for this unknown issue. I'm reluctant to sell her, but I will if required. The garage I use kept asking me to monitor the amount of coolant which I did. The breakdown recovery mechanic said the same, but eerily none of them ever mentioned the head gasket which I found extremely odd. What are your thoughts other than what you've stated to m4rkw?
