Using loads of coolant

[m20b25]

Right, car dumped it’s load of coolant all over the road. Upper pipe had gone. Replaced and a new water pump.

Not fixed. Uses all its coolant within 2 miles and clouds of steam from one exhaust. Engine is the n62 4.8

Would a head gasket cause this much coolant use or more likely cracked block? Or something cheaper?!

Head gasket one bank - a pressure test will confirm. Forget having a head gasket done, it just doesn't work on these. A good used engine is a far better option. To be fair, it's not that common an issue.

Head gasket issues would have pressurised the system and blown the hose to start with.

Cheers. Understand they’re metal, is that right? Any info on why they can’t be done?

The usual issue - the threads in the block let go on tightening but they're worse than the previous M62 for that. It's quicker to swap the engine.

I won't mention tipping bottle of steel seal down its gullet and p/x'ing it.

Whoops!
