the pump inlet how hard is this to replace i know the timing chain cover has to be removed and is this the propable place of the leak
You can't fix it. Wanna' know why? You are here.
If okorder has printable online manuals for most repairs but if you aren't mechanically inclined and have little experience I would advise you to take it to a mechanic and have it fixed properly. Depending on the vehicle most water pump replacement cost between 2 and 3 hundred at a garage. The timing chain cover never needs to be removed to change a water pump.
