1442 Posted July 25, 2003 Share Posted July 25, 2003 I have an SC 400 --1992. It has developed a really bad radiator leak! I fill the resevoir and the light comes on within 10 miles! I cannot figure out how to open the radiator itself and make sure it is full. Can anyone help? Thanks. Quote Link to comment Share on other sites More sharing options...
jzz30 Posted July 25, 2003 Share Posted July 25, 2003 the radiator it self doesnt have a cap you can open a bolt on the top of the block where you add coolant to see if there is any at the top of the block Quote Link to comment Share on other sites More sharing options...
AWJ Posted July 25, 2003 Share Posted July 25, 2003 The radiator cap is the little shiny piece with the yellow sticker on top in the front driver side just in behind of the bumper. If you are not seeing fluid on the ground or motor anywhere, then it may be getting burned up in the motor indicating a real serious problem. Is the car smoking when it is driven? If not, then check all lines and hardware for leaks. It is possible the fluid was really low and is just getting taken in. That is why the level is dropping out. Just fill it until the level does not drop after driving (when the motor is cold only). Quote Link to comment Share on other sites More sharing options...

AWJ Posted July 25, 2003 Share Posted July 25, 2003 D'oh. It's SC400 not a 300. What the? I'm losing my mind here. Look for leaks on the system everywhere and keep a check on the ground where parked and stuff. I just wanted to show off my motor. ;) Checking to make sure you guys are paying attention. I'll think of a few more excuses later. Quote Link to comment Share on other sites More sharing options...
SPORTcoupe300 Posted July 25, 2003 Share Posted July 25, 2003 Also, check your oil for any water bubbles. If you take out your oil dipstick and look on the tip, there should be nice clean oil (if you change frequently enough) If you see any bubbles in the oil, your headgasket's gone and that's why you keep losing coolant. Good luck. Quote Link to comment Share on other sites More sharing options...
jzz30 Posted July 26, 2003 Share Posted July 26, 2003 if your leak is that bad and the water is getting in to the motor the oil should be brown and junk looking. also check your trans oil cus ive fixed a car that lost a lot of fluid that was getting in to the trans where from ??? do you ask? well it got in from the radiator where the trans oil cooler and coolant are cooled. i guess from old age it coroded and went in Quote Link to comment Share on other sites More sharing options...
