Slight squeak on pull away and a few niggles

I've noticed last few days a slight squeak on acceleration. It's a stepspeed but the noise is from the engine. Some times its more noticeable than others but if I Rev in nuetral all seems fine. Hear it more on hard acceleration i.e pulling off on to a round about quickly.



I also noticed that the coolant in the tank seemed to bubble a little although I have a feeling this may just be general movement of the coolant through the system? Link of video. http://ift.tt/1x2js1g



One more thing, from the exhuast it seems to run ok but there's a type of hesitation then a little burble and pop of pressure from the exhaust then it idles normal again and repeats. Not sure if this is anything but you can see a jerk in the engine bay when it does this.



Only noticed these things today as I left it idling while unloading the shopping.
