1995 sl2 - antifreeze leak - where is it? -------------------------------------------------------------------------------- hiyas. so... a 1995 saturn sl2... it's leaking antifreeze... I'm trying to figure out from where. Now, I have it up on some oil changing ramps... the antifreeze is dripping pretty good from somewhere underneath the throttle body/air intake and between the engine and the firewall... or maybe out of the engine, I can't get back there to see. There looks to be the two heater hoses going through the firewall in that area... At any rate, it is dribbling on the back of the engine, then on top of the exhuast pipe... I only mention this to give an idea of the area I am referring to. Any ideas? Things to check... ways to check? thanks. -W -------------------- 1995 SL2 - bleeding the brakes ? -------------------------------------------------------------------------------- Hi. In my so far epic quest to determine where exactly the antifreeze is coming from on a 1995 saturn sl2, I went to remove the air duct/pipe that goes from the air filter box to the air intake/throttle body... and subsequently popped the reservoir for the brake fluid on the master cylinder off, so brake fluid went everywhere. Yay. So I got that part back on good... the reservoir for the brake fluid, but I'm guessing it would be wise to bleed the brakes now. I have bled the brakes on many other types of GM vehicles before, a '65 chevy truck, a 1985 chevy s-10 truck, a '85 oldsmobile, etc.. I just thought I'd check to see if there was anything special to look out for on this electronic gizmo mobile. thanks to all... -W ------------------ Thanks for any help or advice... other than a large amount of explosives to put it out of my misery. -W
Sometimes you get lucky and it is only a hose clamp that needs to be tightened. Many of the original clamps are single use and crimped in place. You have to cut those off (the band not the rubber) and replace with an adjustable one from the parts store. First place to check is hose connections, then hoses themselves. Also check the water pump seal for leaks. Once you've got fluids all over the outside of the engine, makes finding leaks difficult. Sometimes the easiest way (short of adding a UV dye to the coolant) is to wash down the engine with hot soapy water (steam clean?) and wait for it to dry before running the motor. Much easier to find a leak on a clean field. Helps too if you are doing this in a warm climate instead of the miserable northeast where I am now. Brakes - Some cars with ABS brakes need a tool to cycle the ABS and remove trapped air. Others can be bled like conventional systems. I've heard that with ABS you can bleed the system, go and make a hard stop so the ABS engages and then bleed again. Pain in the tail. My L300 does not need any tool to bleed. Make sure that the resevior is full and start with the right rear wheel. Open the bleed port and attach a short clear hose to it. put the open end of the hose in a bottle with a bit of brake fluid at the bottom. have a friend pump the brakes slowly and watch the fluid come out. While the brake is still down, close the bleed port or pinch the hose. let the brake up, open or release the hose and push the brake down again. repeat until you get clean fluid out and no bubbles. Close the bleed port and repeat for left rear, right front and left front. Be sure that you keep the reservoir filled or you'll be starting over. Oppie
More than likely your intake manifold gasket. From under the car, take a flashlight and look up at the intake manifold, you should find your leak. It is usually towards the drivers side of the vehicle. Hope it helps.
