This garage clearly does not know the engine well, so be careful.

It could well be the thermostat - its not the actual thermostat that sticks, but as already mentioned the thermostat housing that bursts, causing coolant loss.

However as has been pointed out, you must check the operation of the cooling fan - it could be failure of this which is leading to problems.

Take it step by step:

1. Is the cooling fan working?

2. Where is the coolant leaking? If not the expansion tank, remove the 2 bolts that hold the engine cover on (the part that says V6 on it) and shine a torch down the V to see if there is coolant leaking or stains. If so then the thermostat housing has almost certainly split.

This is the kit you will need:

Do not guess but check carefully!
