I have a omega 2.5 cd v6 the water punp went have just fixed it have taken it out for a test drive and its running hot over 100 degrees on the gauge i have developed a rattling tapping sound when driving and loss of power i an not losing any coolant heater working fine could this be an airlock or could it be the cam sound seens to be on the right bank of the engine

Not able to help on this but I'm sure one of our experts will be along to give some advice either later (although bit late now) or tomorrow. Don't despair! ;)
-
Not an expert but when you say your water pump went, do you mean it was simply leaking or did it brake up(pump blades).
When the system has cooled down try removing the header tank cap and running the engine up to temperature whilst squeezing the hoses to make sure you have dispelled all the air in the system :).
HTH,
Pete.

the water pump broke up,but i think i got all the bits,

Did you give it a good flush through :question.
-
No i didnt flush it through
-
Might be worth asking someone such as MarksDTM or TheBoy for advice on this one :y.
-
Mate,
dont wait for the worse to happen. Just do a full flush of the cooling system and get out all the gunk. Then fill up again using a 50-50 of VX genuine red coolant and water.
I think this might help you out. Your normal temp should sit in just below the middle of the gauge and your fans should kick in at around 92 deg. By the way, are the fans kicking in?
Cheers

Fans are working fine the noise started about 10mins into test drive heater working fine no loss of coolant, power started to run sluggish like it was missing then it started running hot over 100
-
Its a 2.5 so should run about 95 anyway...but as said flush the system, constant overheating will lead to HG failure so get it sorted soon and dont use it till it is (if at all possible) :y
-
Check the cam timing.....did the failed water pump shred the belt?
-
The timing belt looked intact
-
Is it timed up correctly though....did the aux belt get shredded?
-
I'll be passing High Wycome on the 20th and can help out with a cam locking kit.
The concern here is that when the aux belt shredded something got trapped in the cam belt causing it to jump a few teeth or more.
Until you are absoutely certain the cam timing is ok - don't run it
-
the aux belt did not shred the water punp blade halfed and the water pump bearings were every where
-
Could be a few of things causing the overheating.
Could be an airlock like you suggested, in which case it would probably be best to drain the system and re fill, then with the filler tank cap off, squeeze the bottom and top radiator hoses untill no more bubbles come out.
If its not that it maybe the thermostat has jammed shut. When the engine is hot is the radiator hoses and rad its self getting hot too? If so the stat is working ok.
-
How far was it driven with the knackered water pump?
-
less than quarter of a mile it was driven
-
What i forgot to mention is when the water puup went the battery light came on the power steering went the tenp gauge went up the water pump shreded the blades and bearings. the auxillary belt was thrown
off bet not shreded
-
have checked the rad and pipes they are hot heater blowing hot no loss of coolant, fludhed engine car still rattling and tapping on right hand side of engine if looking in from bonnet passenger side if in the car am going to strip it back now to look at the timing belt how would i know if a cam or a piston has gone douing my head in
