The check engine light only comes on after loosing coolant and i have replaced
the expansion bottle and thermostat there is no visible sign of coolant leakage
If you're losing coolant, it has to be going somewhere. See if you have white smoke/vapor coming from the tailpipe. If so, that's coolant burning up in the cylinders. You might have a blown head gasket.
