Hello, my name is***** can be caused by a number of things. It can be caused by an engine accessory or pulley or it can be as serious as an internal engine problem. If you are losing some coolant also then I would first suspect a failing water pump. Typically when the pump fails on this engine it will make this kind of noise. You will need to start by running the engine with the drive belt removed. If the noise continues then you will have to remove the front timing over to inspect the components in there. If it stops with the belt removed then it is one of the engine accessories, possibly an alternator. I hope this helps. Let me know if you need further assistance.
