Guard slipped off and was rubbing on front timing cover.
This is how I fill my cooling system, haven't had a problem.Quote:

Take for a drive till temp gauge shows normal and heat coming from heater, drive home and park and don't touch overnight.
Next day water level in bottle should be at correct level, too high, siphon some out, too low add, works for me and is how it says to do it in the workshop manual, good luck.
As for the noise it is hard to tell, remove the drive belt and spin pulleys and tensioners by hand, feel for roughness and listen for rumble. How long was the water pump dry for during head work, have you used Coolant? Could also be the fan bearing in the Timing cover, see how to fix on Forum, Regards Frank.
yea im assuming its a bearing or pulley noise. the water pump is brand new so im hoping/guessing its not this. yes im using coolant. i know the belt tensioner was a bit churpy before. noise seems louder near alternator or just behind the housing that holds it. the alternator is only 1 or 2 years old though. ill check the dust cover too when i get home. was really hoping to drive it to work today. bit peed off.
isnt the thumping noise just the injector pump ticking? i hope there is not another noise you are hearing that im not :o
check your lash caps, check you didnt leave a spanner in the rocker cover (Im not even joking Ive seen it 3 times) and check the tensions on the bolts on the pullies
slack off the AC belt as well.

ill go through all the pullies, bolts, tensioners tonight. the aircon belt is new. so possible i put it on too tight. but sound seems to come more from alternator water pump side.
slacking the ac belt is to elminate the AC running gear.Quote:

It probably is just normal noise, but I'm not "qualified" enough to judge :). Different recording devices amplify and distort certain frequencies when recording so it may sound different than it actually is. Mine has same thumping noise. Never saw any problem developing from it.Quote:

Do you guys actually mean take one belt off and start the car and then put back on and take other belt off and start the car?
Ok started the car, both belts on just to see and noise is there now wven with cold engine. So somethings happened while i drove it last night.
Def one of the pulleys on serpentine belt. With it off it runs quiet
