Thank you for allowing me to assist you, my name is Joe and I will be happy to assist you with your concern today.

Was it running hot and rough before you replaced those items or did you just have a leak?

Have you preformed a block test which uses a chemical through the cooling system to check for exhaust gases? This would help indicate a failed head gasket for instance.
