So tonight when doing my timing belt, water pump, crank seals and camshaft seals the top of my radiator got a piece broken out of it. It is right where the hose goes into the top of it up by the cap. Is this something that can be repaired. If not what should I go w/ for a radiator. I see some Koyo's on ebay for around $130 shipped. Is that a good option? or should I try to have a radiator shop fix it. I was told by a friend that it is possible to have a new top put on the radiator at a shop. Does anyone here know anything about this. I plan to do some calling around tomorrow.
thanks
