In order to improve water flow to the side jacket on the C engine I suggest removal of metal as per the marked line on the attached photo of my waterpump housing, this combined with previous postings of removing the casting flash into the side jacket should see an improvement.

Incidentally a Land Rover Mk 2 service kit is quite suitable for the MGC waterpump.

Hello Carroll,

I bought the Land Rover kit across the pond here in the U.K. and yes the kit part # is RTC 3072. You may need to reduce the shaft at the pulley end by 10mm, also carefully check the seal.

Regards improving the impeller, I sourced a unit through Speedway Motors, Lincoln, Nebraska, photo attached. A certain amount of small machining may be required.

Please let me know if I can be of any further assistance.

Oh how I wish I was living back in the USA, my six years living & working there were awesome! So are the people, totally misunderstood over here.

Boy, do we need a McMaster Carr!

Regards,
Clevis.

Thanks Clevis,

Do you have any additional info on the impeller, like any manufacturer or number for it.

Yeah McMaster Carr has bailed me out quite a few times for odd fasteners and such.
