Hello People, can anyone advise on how to replace the water pump on a 1997 Brava 1.9td 100. Never done it before and need pointing in the right direction!!!!!
 
you need to remove the timing belt so its a big job, especially when you consider the added complexity of pump timing on the TD.

with the belt removed you literally unbolt the pump and pull it off, easy peasy, but getting the belt off and then back on without compromising the timing is difficult.

here's a guide for timing belt if you do decide to replace the pump yourself.. note locking pins can be substituted by long bolts in some cases, flywheel locking tool not really necessary if you're careful, i.e. put gearbox in neutral, disconnect battery, do not turn engine once belt is off etc. make sure to turn engine over a few times by hand using a socket when finished to make sure the belt is running correctly and everything is ok.

Thanks for the help fella's, I've had a severe overheating problem with this car, so far I have replaced the pressure cap on the expansion tank, checked the thermostat, cooling fan, flushed the system through to make sure it's not blocked and now I've checked the water pump and it's fine. There are no leaks anywhere, I can't see any water/oil contamination and the oil level is constant. Is there anying else to check before I push on to the head gasket?
 
do a compression check to see if its head gasket, a compression tester only costs £10-20 and its easy to use, all you need to do is remove the sparkplugs.

is the radiator getting hot water to it? if it overheats and the radiator isnt hot then the thermostat could be stuck shut, not an uncommon problem.

You can't really do a compression check on a diesel as the compression is too high. Petrol cars have a much lower compression rate hence you can buy the tools readily from Halfords etc. Also diesels dont have spark plugs Jug. :) Well you can do a check but the actual tool costs mega money and hardly anyone stocks them. Shame really, but if you can get a garage to test it for you that be good.
 
Why are timing locks sold then? Its a genuine question, as I am struggling to get my engine running cleanly and quietly.

I wondered whether to buy a set, as the pulleys do move around when you tighten up a belt. The slack in the belt itself means that the marks move around a bit. Is the timing SO accurate that timing tools help - or are they just there to save time? :confused:

sorry forgot we were talking about a diesel.

a compression tester suitable for a diesel costs more (£50-70) because it can take up to 1000psi and comes with half a dozen different adapters to fit different engines. for less money you could get it tested at a garage instead

the locks are sold so you can make sure you have the timing perfectly set when fitting a belt. you dont really need them if you are replacing a belt when the timing is ok to start with, but when you're repairing a snapped belt its almost impossible to set the timing correctly without at least locking the cams in the correct position. if you're not very confident then they are also very good to use when replacing a belt and make life much easier.

When you say its impossible Jug - I'd say its easy to arrange to take up the tension on my belt - such that - when you've finished - the cam marker lines up exactly with the mark on the cover. (this is the old TD engine fitted to some early Bravas)

Do you mean though - perhaps - that the timing tool is more accurate than the mark on the cover - and could a couple of mm or so adrift make a big difference?

imagine your belt snaps on the way to work one day, you dont have any timing marks and you've lost your timing. correcting it is almost impossible without timing tools.
 
I could'nt get a diesel compression tester so I stripped the head off and lo and behold, a blown head gasket. I suppose the positive way to look at it is the money I've saved doing it myself, and more knowledge gained. Thanks for your input fellas, it's good to know there are like minded poeple I can call on for advice.
 
Just thought you would like to know, job done and the car is running as sweet as a nut.........but I don't fancy having to do that again!!!! Any suggestions as to why the car overheated in the first place? I can find no faults with the cooling system, the oil and filter had recently been changed and the fan comes on at the right tempreature.
