More then likely you have a distortion on the mating surfaces so what I would do is remove the gaskets and replace them with gray RTV.

Here is a guide that will help with replacing the water pump and thermostat again which is what you need to do in order to replace the gaskets:

Below you will find the process from the manual which will help with the detail.

Let us know if you have other questions. Thanks
