	15 miles down the road in my XJ8 I get the low coolant warning (had it once before but it barely needed topping up) Pop the hood to a grand plume of steam: Leave it for 15, refill, to find this gushing out the front of the engine. Any idea what's likely to be the culprit? I know nothing about these engines but have read that water pumps give up, and it's bolted on about here...as well as thermostat/thermostat housings

	If the thermostat housing is the plastic type change it as a precaution because they are known to be weak. Also that leak is a real gusher and must be something obvious but can't see in the vid. Water pumps are another weak spot and best to buy a new one to be safe. It has to be something broken to get a leak like that. I would buy a metal thermostat housing and new water pump .
