Alright guys, recently my truck started making some noises. When you cold start it you cant hear it but you can feel it in the upper rad hose. When it warms up it when you can hear it. You can feel it in the water outlet I think its called, that goes into the timing cover. You can only feel it in the cooling hoses, nothing else. Was told it may be the water pump? Anyone wanna help me out

 

what kind of noise? rattle? squeal? clanking? any maintenance history?
