Is this a Water Pump failing ?

[Steves_TR6]

Hi TR experts !

 

Checking the TR6 over this afternoon after a couple of weeks, and i see a stain on the engine block below the water pump, or the metal pipe from the heater.

 

The stain gets a drip of water on it when the engine runs, so its a leak !

 

My question is :

 

Is this a water pump / bearing leak or perhaps a leak from the steel heater pipe which is in the same area?

 

If it is the water pump then obviously i need a new one, in which case I think i recall that some are of dubious quality ? , where should i buy from ??

 

If its not the pump any suggestions welcome !

 

thanks in advance.

Have you considered the gasket the one between the head and pump housing.

Try re sealing the tube adaptor into the pump housing.

There is a core plug in the block just behind the pump housing I think.

If it is the pump you should see a line behind the pulley

Hmmm, thanks for the suggestions.

 

Might dismantle, clean and reassemble with new gaskets.

Made it home early from sailing today, so off with the water pump for examination!

 

There is a trail of brown stain, same as in the pic above, from the water pump bearing hole.

So convinced the problem is the pump I replaced it, along with a new 82c thermostat and fan belt.

 

Car runs a little warmer now, just below half way rather than just over a quarter.

 

Temp nice and steady even after a good thrash and with a bit of traffic, and no leak !

 

Just need to drain and replace antifreeze next weekend and all should be good again.

 

A genuinely easy job :-)
