Coolant leak from engine block

Hi,

I found a severe coolant leak on the driver's site of the M103's cylinder 6 right at the expansion/ freeze plug.
(It's not the infamous engine oil galley plug, i.e. threaded freeze plug for block heater on the passenger's side!)

Well, now I was wondering whether there might be an 'easy' way to replace that plug besides taking off the intake manifold...
Yeah, I couldn't think of an any more inconvenient location.....

Has anybody ever done this?

Btw, part number seems to be 000443-034002

Thanks!

Thanks for bringing this up - I'll never again refer to them as freeze plugs! ;-)

Wonder how solid those rubber plugs are.....

I had a car with a plug that rusted out at about 40K miles. The only way could fix it without pulling the engine was with a rubber plug. It was still in there when we traded the car in several years later.

Thanks for that information! I was looking at those today and thought they could be very helpful given there is almost no space to press a new plug in. I actually was wondering how stable they were and if that was a long lasting solution. It appears to be.......
