Is there a water system diagram available for a honda ballade 150 luxline 1998?

There is definitely no valve there - the only pressure relief valve would be inside the radiator cap. What you see is leakage from a water pump bolt or from the water pump itself. You could try applying a waterproof sealant to that bolt, but it's tricky - allow the engine to cool FULLY, then remove the bolt and hold your finger over the bolthole while a helper applies sealant to the bolt threads. Quickly put the bolt back in the hole so you don't lose very much coolant, tighten the bolt again.

If that doesn't do it, then the leak is really coming from the front seal of the water pump - meaning the water pump needs to be replaced.

How do i change a water pump on my 1994 honda civic ex coupe 1.6l engine?

Stop leaks rarely works and are often a waste of money. Before going after the water pump, make sure it is that, that is leaking. Many of the smaller engines have the water pump in line with the timing belt, meaning both will need to be changed.

  1. Step 1 Drain the antifreeze from cooling system. Remove belt from water pump. Examine and see if you have to remove anything else to get out the water pump. If so make a diagram of everything you are removing so you can put it back together.
  2. Step 2 Remove the hoses from the water pump. Find all bolts holding the water pump in . Loosen each one a little bit. After all are lose you can then remove them. Remove water pump. Put new gasket on and install new water pump. Hook up hoses to water pump. Look at your diagram and replace everything you had to remove earlier. Put the belt back on.
  3. Step 3 Shut the drain on system and refill cooling system. Make sure you use the antifreeze that is designed for system. Run engine for a couple of minutes. Check for leaks and check coolant level. Add if necessary. If there is no leaks you are ready to go.

I have a 1983 ford econoline van. Do you have a diagram of how the water pump is mounted onto the engine

Short of buying a haynes or chilton manual. the basic instructions are, remove anything that is in your way. fan, fan shroud and brackets. Buy the new pump before starting and place it flat on a piece of cardboard. Use a magic marker and trace it's outline and punch holes through all bolt holes. As you remove bolts from pump, put each through it's corresponding hole. Make sure you make note of any spacers and bracket locations. Once the pump is off make sure that you remove every bit of old gasket material before putting pump back on. Generally it's best to use silicone sealer on at least the pump surface and place the gasket on the pump, waiting 'till its nearly dry before installing (keeps it from moving around while you are working) I also put a thin film of silicone on engine side of gasket just before putting it on. When replacing bolts, snug them finger tight only 'till they are all in. any bolts that will be covered by a bracket need to be tightened first before installing bracket. If you took good notes, the job should not be too difficult.
Only change your pump for the right reasons: If the pump is leaking or the shaft bearing is loose and or the bearing is noisy. Changing the pump for any other reason is a waste of time and money.
replacing a pump that is not leaking will not cure an overheat problem.
good luck....any problems, just ask.
