When she blew on the M6 I wonder did you notice the exhaust gas colour, if its the head it would be blowing steam like crazy at the speed that the coolant loss occurred ie. when filled you only made another mile!
Might be worth topping up again and running until warm and see what happens! As an aside I would recommend treating the engine with slick 50. don't let anyone tell you all engine additives are crap this stuff is fantastic as it coats all surfaces in ptfe . look it up! I first came across it when flying and was told the chap who invented it just couldn't get any one to take it seriously so after treating his aircraft engine with it he drained it and flew around New York for 20 minutes without any oil! I can well believe this as since I've been using it, circa 1986, all my cars have had no engine problems at all. whilst working on a building project in the early 1990's i bought a second hand ex GPO Vauxhall combi van ( didn't want to stuff the LR) and after getting it serviced on one occasion I picked it up and drove it around for the day doing about 200 miles in total. As I got back towards home it started to feel a little unresponsive, sluggish to accelerate. The next morning I went out to see if I could see what was up! No water at all! On closer inspection the problem was simple the tw  t stealers when changing the coolant had drained it using the rad temp sensor as the bottom hose was a sod to get at and they hadn't refitted it properly-- hand tight only-- so under pressure it lost the lot! so I refitted the sensor topped up the coolant, water first to flush and check, and ran her up to temperature. Perfect! Kept the van for another two years with no problems. no other signs were evident and I wondered why the temp gauge hadn't gone sky high! when it was running at temperature I checked the in car gauge and it was only marginally lower than the night before. So verdict, we have never run a car without this wonderful stuff! Oh and it will improve your MPG to! |

I agree, but use it for low cost vehicles you won't keep for long. Every coating reduces heat transfer-values. The stuff covers the root cause. It's better to investigate an fix the root cause

Looks like head gasket...?
Lots of pressure in the coolant tank before the engine is even warm? |

Definately! But you have to keep in mind: If it turns out that the gasket itself or torque of the screws have no issues, there might be a crack inside the head. Some cracks do not show when gead is under pressure and in hot water. So you have to go for a new or overhauled head.
