i have just had my new front splitter sprayed and plan to put it on the car shortly, however when faffing with the car today i noticed the radiator grills are badly corroded and crumbling, so i thought it may be a good idea to change radiator when i remove the old splitter. but there seems to be a vast difference in price on some i have looked at, ranging from around £50 - £200. also may replace hoses, but dont want to Pay £55+ for silicone hoses, where can i get the std ones. i have a 03 t sport with a/c. can anyone advise.
