Hi Daniel, Are you talking about the various pipes that connect to the surge tank on the 2.5l engine?

Not a diagram, but if you go here, where I have some detail on changing the rear sparkplugs (which requires removing the surge tank if done from above), there's a photo that points out the approximate location of the lines.

In summary, there are four lines connected the surge tank:

1. The brake booster vacuum line at the rear of the tank.

2. The purge line for the fuel evaporative emissions canister (which goes via the purge solenoid assembly to the evap. canister on the right).

3. The crankcase vacuum scavenge line which then splits to the right and left camshaft covers,

4. The thin manifold pressure compensation line running from near the throttle body to the injector fuel rail pressure regulator.

Is that what you are after? Can I ask what's behind the question?

Hi again Daniel,

On vacuum hoses, I did respond to your post above for info on the connections to the surge tank. There's no diagram as such for the vacuum system that I can see in the workshop manual I have on the 2.5l V6 model.

On water pipes, there no diagram in the Cooling System section either and not a lot of detail on the full circuit. Can you give some more detail on what you are after here? Are you after just the cooling system related connections to the engine? (There are also coolant pipes running to the front heater and down the back to the rear heater, air purge pipes that are technically part of the coolant system, etc). Happy to answer specific questions by looking at mine. (It is a 2004 model, but I don't think there's substantial if any difference).

Cheers,
Peter

Hi Peter

many thanks for your reponse. there are toe places for vavuum pipes on the back tappit cover and two on the front tappit cover i need to find out where they need to be connected to

Cheers

Daniel

Peter has just about nailed the response

Look for one of my earlier posts - it had the engine manual.

That has some pictures identifying everything - connection ID wise.
Not much in the way of hose routing though...

The nylon tube goes from one side of engine heads to the other.
Its rubber hose ends are usually brittle & cracked - replace if necessary)
Connects onto front (drivebelt end) hose stubs- and tees into stub atop throttle body near throttle wire connection.
The rear (air filter end) cylinder head/surge intake stubs connect to the stubs atop throttle body closer to air filter.

And you also have the brake vacuum hose as well.

You never take any pictures before dismantling?
Or did you inherit a broken down job?

You also asked about the coolant connections.
You fine with them now?
Be wary of the brittle plastic fittings going into engine- don't swing on 'em
Crack and leak easily...

Daniel, here's a photo of the two breather connections from the (visible) camshaft cover.

The nearer one (i.e. towards the front of the engine) connection goes to the T-piece you can see just above the inlet manifold side of the surge tank, and from there to the connection you can see on the top of the throttle body, on the surge tank (vacuum) side of the T/B. (The other side of the T-piece goes to the corresponding connection on the other bank's camshaft cover).

The other connection on the camshaft cover goes to the 2-way connection on the top of the throttle body that's on the air cleaner (atmospheric pressure) side. And the other hose on that connection goes of course to the corresponding connection on the other bank.

HTH.

Did you need some input on coolant connections?

Cheers,
Peter

Ahh didn't refresh & see Conglomerate's reply before posting above, so some overlap. The photo should help with routing.

@Comglomerate, a related question for you - where are the PCV valves on the GV6/K5, I assume under the camshaft covers?

Hi Conglomerate, thanks for your input, i have searched for a manual but to no avail, its a project that i took on that was already stripped due to overheating and i purchased another motor K5M and hence i need all the advice i can get to make it work efficiently

Vacuum hoses connection and crankcase breather PCV Valve

as far as I'm aware the K5 engine uses a vacuum orifice as CCV
- in lieu of a PCV valve.

Our air inlet manifold/surge is different from the Rover KV6 .
But it handles the oil sucked thru from crankcase into it better.
Clean the cummed up mesh at Breather connection within cylinder covers when able..
The Rover guys went thru a period of installing a catch tank.
MG ZS 180
You'll see the oil inside your air intake/VICS chamber end and throttle body.
A good clean of everything a good idea at timing belt change intervals...

I otherwise always leave throttle body connected to surge/air intake otherwise. just take it out as one piece..

What had me looking for it were the multiple references to the PCV valve in the Kia FL workshop manual for the 2.5l engine (e.g. ‘Replace faulty PCV valve’, etc, etc).

When I took the LH bank camshaft cover off it was clear that the manual is not correct, the engine uses a valveless CCV design.

So your assumption's right, I can see the scavenge orifice pressed into the bottom of the vacuum fitting in the camshaft cover.

Before touching or cleaning anything I put a clean plastic hose on the vacuum fitting on the cover & applied suction and there was good flow (which I thought was pretty good after 110,000km). So the ‘block’ of mesh that filters it seems to be effective enough. There was very little hard char on the orifice side of the mesh.

The orifice is about 1mm (0.040”) diameter – at least that’s the largest diameter piano wire (gently applied) that would go through it. Once cleaned though, the flow was much increased with the suction test, so it was certainly partly clogged.

It seems like a 1mm / 40 thou wire up the vacuum fitting on each cover at intervals would be a good idea, & simple to do. Would need the surge tank off to do the RH bank, so likely in combination with something else e.g. sparkplugs.

Its rubber hose ends are usually brittle & cracked - replace if necessary)
Yep, the rubber of the vacuum and breather hoses on mine is brittle and splitting alright – what do you replace yours with, I assume something with better heat resistance.

Breather hose - rubber ends

just some hose from the auto shop
Fuel/oil resistant.
Try & route away from any direct hot metal contact...

Usually use some sealant on the nylon tube line
- as well as just pushing the hose ends over it.

I thank you guys too...The Carnival I bought had terrible brakes, vehicle almost unstoppable. Some clown had connected the brake booster hose to the rear engine breather pipe....:p
