I have returned from a 5 mile or so trip several times now to have all my coolant come pouring out around the coolant cap all over the ground. This is a fairly new cap and I don't know what else to do. My mechanic has put a pressure pump to try to find leaks, even let it idle with the pressure tester on and no leaks. Does anyone know what the solution is? I've had the overheat light come on 2 times now as the reservoir drained out on the highway through the cap. There is no white smoke coming from the tail pipes, no head gasket leak. It's simply coming out of the top of the coolant reservoir and around the cap. And POURING out after running for 15 minutes or so. The fans are coming on fine too.
