Hi, I've got a 3 litre, V6 TS magna.
On New Years Eve, it blew the bottom radiator hose. By the time I pulled off the freeway, the temp needle was nearing the red zone. I replaced the hoze, did a cooling system flush and added 30% Eth. Glycol. Temp needle was half way between H & C. All was well until yesterday, when it dumped all its water again. Oil is clean, with no mayo, and like before temp needle was nearing the red zone before I could stop.
When I fill the radiator, I get a steady stream of water running down the Passenger side of the engine block. It seems it could be coming from the manifold, or maybe there is a core plug up there that has rusted through.
Is there a core plug up there? I can't see as the aircon pump (or is it power steering? - I can't remember while sitting at the computer) and oil filter are in the way.
Whatever it is, it sounds expensive....
Cheers for any help or comments!

Its the water pump up there under the power steering pump. The part isn't all that expensive but its a lot of work to get out.

Cheers, Rob...

Looking at the manual, it seems like a pain in the a$$.... I don't like messing with timing belts - but, hey, maybe it would be a good time to replace it?!???!!!!

Might pull a couple of bits off and confirm the pump is faulty. Sounds likely, though (certainly more likely than a manifold gasket fault...)
Thanks again

Chris.

I just did a timing belt recently on my 3.0L V6 TS. Took me about 8 - 10 hours over a couple of days to do it all - taking my time. It looks a bit daunting when you see it all in the workshop manual, but it wasn't really that bad. If you're gonna try it, I'd recommend you have a half decent set of 3/8" Drive and 1/2" drive sockets, spanners, a breaker bar or long extension for your ratchet - for the cranskshaft pulley retaining bolt, a trolley jack AND axle stands, as you have to leave the car supported on them while you re-position the jack under the engine as you have to remove one of the engine mounts. A torque wrench would be handy too for the cranskshaft pulley retaining bolt, although I just marked a line on it with a scriber before I un-did mine.....

You might also need a 2 or 3 legged puller for the crankshaft pulley - I just about managed to wiggle mine off - took me about 10 minutes of wiggling and persuading with a mallet, but a puller would have been a lot easier.

You'll also need a BIG flat bladed screwdriver, or even better a crowbar. When you're trying to un-do/do up the crankshaft pulley retaining bolt, the engine naturally wants to try and turn over. The easiest way to stop it doing this is to remove the starter motor to gain access to the ring gear, then jam the screwdriver/crowbar into one of the teeth (two man job - one to jam the gear, the other to un-do the bolt).

Haven't tackled a water pump yet, but looking at the workshop manual, it doesn't look too bad once you've got the timing belt off.

Hope this is of some help.

ayyyy another Clarky, our name's royalty brother! lol, dont mind me...

I salute you brother....

I had great trouble with the crankshaft pulley nut but after suggestions here on the forum I rested the breaker bar on part of the front suspension and gave the engine one kick over on the starter motor. Worked well. Took the spark plugs out first to make it easier.

How'd you do it back up again?

I jambed a large screw driver through one of the holes in the pulley and lodged it against part of the block.

However I would in future use the large screw driver on the ring gear idea mentioned above. (Not as risky)
