Sports: Re: [DucatiST] ST3 cracked radiator

All,

I welded the ST's radiator crack was approx 1 1/4 inches long down the formed radius of the LH side tank. All is good now looking at the material hardness there was a marked difference between the flats and the radius of the side tank so an thinking that some resonance was setup through the 'softer' material thereby causing the crack to form. Will be interesting to see how the weld repair holds up............................................

Greetings Doug,

Sounds like a rare occurence to me, sir.

I know she get's warm over there, best to have the radiator cap tested for release pressure, usually 15 psi or so.

If the repair is too costly check out Ebay, or Gotham Cycles etc. There's a ton of radiators out there. IIRC, most will fit, but it's the hose fitting arrangements that are particular. Just compare photos of the radiators to yours. I've seen a bunch sell for $100.00 -$150.00 with dual fans to boot.

Good luck, and good hunting.

Ciao, Nick Alaniz, 2002 Ducati ST4$, Sacramento, CaL.

Good day all,

Has anyone heard of or had a cracked radiator on an ST3S? Bike is 2006 model first registered Jan 2007 covered 46500 miles never dropped at any speed and always had radiator guards fitted. Crack has appeared on the LH side tank no physical damage to radiator, not even a paint flake, apart from the crack which seems to have propagated from the two rivet holes half way up the tank.

I will be welding the crack as Ducati have quoted 2602 Singapore dollars for a new radiator, guess there is not a great deal of demand for them at that price................ I am just curious if someone else has similar problems, not just hose weeps.

Thanks in advance.

Doug
