| 98 deville---need coolant overflow expansion tank 98 deville: my coolant resevior overflow expansion tank went bad with a leak....i was wondering a couple of things: first, is it easy to pop out and replace? second, its a small hole but enough---would j.b. weld work to hold the leak if applied correctly? thirdly, does anyone know of any oem or good websites to go to buy another one?????? |
