I have a cadillac 1995 DevVille and was wonder how you check the radiator fluid, when the resevoir is an opaque black, other than shining a light into the reservoir and taking a peek at the fluid level. Any suggestions would be of great help.
Yeah, just take off the radiator cap and see where the fluid level is. It should be at the top, if not add some... BUT MAKE SURE YOU LET THE CAR COOL DOWN!!!!!!!! DO NOT TAKE OFF THE RADIATOR CAP IF IT'S HOT! I did that once, my radiator cap doesn' get hot so i took it off but my engine was hot and it shot out everywhere.
some cars dont have rad caps on the radiator ,but have one on a surge tank, but i forget the name of that type of system and gm uses it alot . wouldnt be surprised if his deville had it , id say just a flashlight and a eyeball , or maybe it has a sensor and lamp for the radiator fluid level
