my sis has an '04 tiburon gt auto tranny with about 80xxx miles. where is the thermostat located on these vehicles? also, she has a cracked radiator and the local shop wants to charge her $300 to replace the radiator-is 300 a reasonable price? the price includes the new radiator($115), new antifreeze and 2yr warranty. i've only worked mostly on my nissans and i'd usually change the thermostat with the radiator but have never worked on a hyundai before. thanks for the help.
