20 Most Recent 1999 Saturn SL Questions & Answers

Take it to a shop and ask them to put it up on a lift, take a look and figure out where it is leaking. They can tell you and also how much to fix.

Yea could it be in fuse block under hood

The reverse lights work off a switch near the brake switch at the brake pedal area. If loose it will not work. If tight its probably shorted out

Sorry GM doesn't publish this info any more.

check timing belt!! good luck!!

if the thermostat has not been replaced i would do this, also while doing this flushed the radiator system out, is also best to back flush they system, also when was the last time the water pump was changed, as over time the fins on the water pump will deteriorate and cause overheating problems, with a/c it will help keep the engine cooler, but you need to check that the parts ive said have been done as this is the main cause of the engine over heating, you will probably find the thermostat is not working properly and there is rust red water in the system, and rusty parts in the emptied water thats why you will need to back flush the engine youtube back flush engine, top up with new antifreeze recommended for your area and engine. and bleed out the air from system. if the water pump has not been replaced in 5-10 years it needs changing.

You have to open the bleed ports . there are several located by the engines thermostate housing and near intake hoses. It will allow the air to escape .

Sound like a blown head gasket. Changing the knock sensor will not remove a knock. It's a sensor.

there is a fuse for the radio in the fuse box, if your power was ripped out , find the radio fuse and make a new conection from there ground can be made conecting to any metalic part of the car

yeah. This is only a temp fix. GM has a bulletin warning against the use of Slick 50 w/PFT. It can clog oil passages

This can be caused by a stuck blend door or a clogged heater core. Can you hear the blend door moving when you turn the temp knob? If not, it may have disconnected from the control panel or blend door. If the door works, remove the heater core and flush it or replace it.

Sounds like a head gasket, the oily substance is actually oil. Do not drive the vehicle, at some point a $1000 repair will into $3000 repair when the engine seizes.

Blown head gasket or cracked block

You don't state mileage on the car but I'm betting well over 100K. The master cylinder is sold as a one piece kit which has the line and the slave cylinder attached to it. More than likely your slave cylinder has gone bad, which means you'll have to drop the transmission to get it out as it's an internal mechanism that pushes your throw out bearing to engage your clutch. Yes it's time to also change the clutch and pressure plate too, you may as well as long as you have to drop the transmission AND in order to do that my friend, you're going to have fun, because the whole front of the car has to be lifted and the WHOLE X sub-frame has to be dropped which means struts and all have to be disconnected. NOT a fun driveway weekend job unless your young, don't mind bending and kneeling on concrete and have power tools, air guns, to make it easier. Strong arms if you're going to attempt it with hand tools. Good luck to you.

You have a high resistance problem in the electrical circuit ,Possibly I/P fuse box where the relay lives . Do you know how to use a voltmeter to do electrical testing ? Testing Electric Fuel Pump Problems with Voltage Drop Test

check and / or change the CPS it is behind the starter
