I was hoping to get some input prior to riping everything apart. After a lot of work getting a 01 F4i running again (been sitting for 4 years), changing all the fluids, filters and spark plugs out, FPR replacement, gas tank replacement, shooting some marvel down into the cyclinder, etc, etc. it started right up and has been running great over the last week. That was surprising in itself... Those engines are just bulletproof.

But I noticed about two days ago that coolant is leaking from what looks like one of the hoses on top of the water pump at the connection point (the one towards the back that goes up under the fuel tank somewhere). It is a very slow drip that only happens while the bike has been running for a couple minutes and stops after it has been turned off for about 5 minutes.

Should I start thinking the worst that something major could be wrong? What would that be? Or is it common that a hose or clamp may be bad and just need replacing?

I get concerned as it was sitting for such a long time after an accident and I could be looking at something major engine wise or some sort of pressure issue. It is pushing a bit of white exhaust at higher RPMs but currently I have Seafoam mixed with the gas and oil to clean anything out so I assuming that is what is causing that. Otherwise it seems to be running great.

Thanks in advance! These forums are what helped me get it up and running again thus far.

 

check the hoses to see if they have dry rot.If so just replace the hose.

 

Your problem sounds exactly like the one I had when I first bought my bike in the fact that after the bike was warm it would leak until it was shutoff and cool. It turned out it was a bad water pump. I replaced it and haven't had the problem since.

 

I ordered the hoses to go for the cheaper route... Crossing Fingers...

Thanks for the replies. I will post the results once I replace them.

 

im having the exact same problem right now... Def wasn't my hoses so had to cough up 120.00 for a new water pump..
