I am near the end of my "free 2003 S60 2.4t" project that came to me with the motor occupying the passenger seat, back seat and trunk...
I am buttoning up the details and adding fluids. After adding coolant to the expansion tank I have a steady drip from where the metal coolant pipe enters the back of the block at the water pump. Anyone ever use some sealant to fix a leak at this union?
More background. The PO that disassembled the motor left the metal coolant pipe in the car, I realize now that I should have pulled it and installed it on the motor before the exhaust manifold and before dropping the motor in the car. It was TOUGH to get it in. I did replace the o-ring at the pipe inlet and I did clean up the pipe before working it into place. At this point i would hate to take it all apart, but I might need to. If a sealant could work, it might be easier to pull the water pump and apply it there, I am not sure that I could get a good look at the o-ring from that side. I do have another motor and a T5 (motor disassembled...) that I can use for parts or reference.
Some useless details... I was able to crank the car, sounds just fine, but no fire. I blew out the fuel line back to the filter and replaced the filter but I don't even know how much fuel is in the tank... because the gauge cluster is out... Right now I plan to get it running before diving back into the coolant leak, that way I other issues can be determined and a strategy for getting them all sorted out.
Thanks in advance for your thoughts.
