My 2002 XK8 has a strange coolant leak, under pressure no leak can be found however when the car is stopped after driving I notice a small puddle of coolant under the engine.

The engine was rebuilt last year with new top and bottom work.

Anyone had the same problem?

Thanks

 

You've got one of those slow leaks that when the engine is hot, it evaporates. When sitting and the engine is cold, it will make its way to the ground. Check around the thermostat housing first.
