I would clean the heads up at same time as doing timing belts.
Replace head gaskets as well.
For that age vehicle anyways. But check your vehicle history on Vcheck.
As its likely the engine was changed before ya got it?
And new belts fitted anyways....
But you really do need a manual. The alignment procedure needs to be understood.
Ebay sell the V6 gasoline 2.5L CD. The kia site no longer has the appropriate details for our Carnival engine from what I can see. Last time I checked.
(You need to access it thru internet explorer - wont work with other browsers)
Replacing timing belts fairly easy, just takes awhile, and hard to see the cam shaft belts,
Fiddly replacing those as well - check your final tensioned timing mark alignment with the centre popped back plates crucial.
As you can easily get stuck lifters jamming valves into piston heads.
The risk of stuffing something up is far more than the risk of a modern timing belt breaking !
It does pay to do them yourselves, as ebay is constantly full of vans up for sale after a
gasket/timing work. The big shops just rush thru the job, and everybody is human - mistakes happen. And the engine isn't tolerant of mistakes at all.
The carnivals V6 2.5 was essentially unchanged up until 2006.
So plenty of spare parts around. Just wreckers charge expensive for engine parts.
The lower drive cog on crankshaft has varying alignment grooves, marks - changed over the years. From description, he appears ok with his alignment, Though confirm your LH & RH bank is aligned correctly, as a newbie mistake is to align the crank, but the top cam pulleys are out... Full rotation of crank.... As top pulleys have two grooves (interchangeable, left to right)
And watch the lifters though after any rework - they can seize - and main timing belt jump teeth. and you get valves/piston collision.
A borescope down the spark plug holes will show if all valves/lfters performing correct as engine rotated....
If vehicle seems to stagger or difficult to initially turn over.
You may have lifter/valve/piston problems. Check piston chambers internally with borescope..
Always important you manually rotate engine a dozen times by hand prior starting !
Valve interference !
