Just had a water hose blow on me van and shat water onto floor

So a few questions if anyone can help.


1.Did it poss. blow due to the age of the pipe.(Is this likely?)
2.Is the thermostat likely to be the cause of the problem?
3.Is this pipe buyable or is a secondhand one the more likely option?
4.Just to add saw a bit of steam coming from front of the van,whats caused this?
Just to add,lowered front of van (-45)yesterday(is this likely to have harmed owt.)
Plus got the usual dash lights problem which started last week and to add, the ribbon is all knacked would be an understatement so know way of knowing without temp gauge wots happening on that side of things...
HELP....



Thanx in advance for any info
