BMW 523i Overheating leaking antifreeze and driven for 5 mins

Hi I had a mechanic change the fuel sensors of my car and when he was driving it back to me he said that the car overheated the temperature gauge went into the red and he was on a A road with no hard shoulder. He had to drive it for 5 mins like this before he could safely pull over. A friend towed him back to his garage and he said that there was antifreeze leaking everywhere. The car is R reg but has only done 76K miles I am quite worried about the damage and whether or not driving it whilst the temperature gauge was in the red for 5 mins might have blown the head gasket. Can anyone help please and give me some suggestions as to what might have gone wrong and costs to fix it?

The mechanic should not have drove when the temp when up and he knows that. The heatgasket is probably now blow. This may be up to $600 for them to fix it. Otherwise check radiator hoses.

2000 bmw 528i overheating

The only way a heater core can cause overheating is if it's leaking and the engine is low on antifreeze. To check it for leaks it would help to use a cooling system pressure tester.

523i overheating

It sounds like it could just be your thermostat sticking. it regulates the temperature of your coolant by opening and closing allowing coolant to pass through the radiator. at the same time the water pump could have failed and just depending on how the vehicle is being driven the temperature rises and falls back and forth. also there could be a clog in the cooling system. Right off hand it doesn't sound like the head gasket has failed but its always a possibility. usually a thermostat can run around $350; water pump $450; headgasket can be pretty pricey $3000- $5000 depending on if once the head is removed its sent to the machine shop for sublet work or not. (highly recommend if keeping the vehicle) and always remember on an older vehicle if the cylinder head is taken off there are plenty of other things that might have to be replaced just because of the complexity of the job and how many different systems of the engine have to be disassembled
