I need a new radiator. The radiator in my car when I bought it was not the original radiator, (plastic reservoir) but worked up till today when I was driving up a hill and got about 3/4 the way to the top and then started hesitating and went blap, blap, blap when I would try and accelerate. By this time I was at the top and rolled down the backside of the hill towards the beach where luckily enough there was a Kragen across the street. I looked under the hood and coolant was blasted all over my freshly detailed engine compartment originating from where the clamp was on the radiator hose return line to radiator. I went to Kragen and got a new hose and clamps and put those on and refilled coolant. This got me back up the hill I came in on but it still hesitated twice when I got towards the top. It was pretty much downhill on the way back, but noticed when I got home that plastic on the radiator had cracked on the top and coolant was spurting out of the crack. I looked in Dearborn and the replacement radiator was $489 for the 64 Galaxie. Does anybody know where I can get a better deal on a new radiator (aluminum) and should I go with a 3 core or 4 core for a 289 w/ automatic transmission? Will a Mustang radiator fit in a galaxie. There is a mustang service shop close to me. Thanks for your help. Oh and would anything else be damaged internally due to to the vacuum leak that occured when I was moving?
