When this happens on my old CX500s it's the water pump mechanical seal.I have a technique for replacing them without having to use the metal cup but don't know if a similar procedure can used on the SV650.


You see the technique here,

Cheers. Hopefully its this or the freeze plugs. In any case its a gasket, a full set of water pumps seals and plenty of fluids and oilf filters to flush out the engine 'if' that is all it needs.

Re: Milky fluids
 

As I'm new to SVs what are the,"Freeze Plugs"?

Re: Milky fluids
 

@ R1ffR4ff - Freeze plugs on a car are special weak points on cylinder block (normally replaceable steel discs) that are designed to pop out if ice forms in water jacket to stop further damage from pressure of ice. I didn't know SV had them

Normally water goes milky when oil gets into it and forms an emulsion, so may be oil getting into coolant somehow, normally water pump seal or head gasket.

Thanks for that.I've been through a lot of water pump/cooling faults over the years and had forgotten that some engines have different designs.
On the old Honda CX500s it used to be that you had to take the engine out and remove the rear engine cover to fix a faulty Mech-Seal but using my way it can be done in-bike :)

Re: Milky fluids
 

Wouldn't a freeze plug be between the water jacket and the outside world? Why compound a frozen water jacket with contaminated oil? My money is on water pump seal.

Known as core plugs on cars...

Re: Milky fluids
 

The core plugs on an SV650 are located either side of the spark plug, between the cam shafts. You have to remove the cam covers to have a look, same as when checking valve clearance.
