Passlock is tricky. There is no way to just turn it off. It is an antitheft system, if you could turn it off, so could a potential theif. I do know of a way to bypass it tho. Check out this link. Alot of info, and some DO IT YOURSELF solutions

If the auxillary transmission cooler is not in the way of the new radiator, if it was me, i would leave it..It will cool the transmission better. no need to plug line holes in new radiator. Hope this Help you??

Hi, you don't really need a part number. You can get a radiator at any parts chain by telling them you have a 98 SL. Here is an example: http://www.autozone.com/autozone/parts/1998-Saturn-SL/Radiator/_/N-jaddlZ8ii30?filterByKeyWord=radiator&fromString=search

Thanks for using FixYa.

The light is letting you know that the engine is oveheating. You did not mention how many miles are on the car, so the over heating could be a number of factors; Thermostat is stuck closed, cooling fan is not operating, radiator is leaking...to name a few.

Radiator... if the light is red, it will be the radiator fluid. All that you should need will be coolant.

it is down on the drivers side of the car about 18 inched from the front it has a tight fit so you will need to have a funnel with a hose, to fix the leak you will most likely have to replace your transmission pan (it cost me $240 at the dealership) the saturn ls1 sits very low to the ground and if you dent the pan it will leak i have replaced mine twice in four years

follow the top radiator hose back the the engine. You will find the housing there with 2 bolts.
