Turn the black reservoir lid counter clockwise and lift it out. It can be very tight sometimes and if you have to do it when the engine is hot, cover it with a towel or something, as steam will come shooting out as soon as you release the pressure and you WILL get burned.
Open hood, look at the rear right of the engine compartment. You'll see a coolant tank. Near the tank you'll see the brake master cylinder with the plastic reservoir attached directly on top.
Most vehicles have a full line or add line marked on the coolant reservoir. Open reservoir only when vehicle is cold.
Hard to open a glove box that doesn't exist. because the mk3 jetta doesn't come with a glove box.
You should add coolant with the engine off and cool, top off the radiator and fill the coolant reservoir to the cool or cold level. When the system is hot or running it will be pressurized and will be dangerous to open. You can however add coolant to the overflow reservoir at any time.
It's on the coolant reservoir. Do not open when engine is hot.
Open the hood and the Coolant reservoir on the '92 Previa is next to oil reservoir on the left side. Unscrew radiator cap from the coolant reservoir, add the 50/50 mix of coolant fluid into the reservoir. (Recommend use Prestone extended life coolant) Fill the coolant into the reservoir, it take about 3 gallon, and be sure that the coolant is pass the full mark of the reservoir. Now, turn on the car, during the engine running (about 10 minutes) kept check the level of coolant be sure it still maintains pass the full mark level. Screw back the radiator cap to coolant reservoir. Run engine for another 30 minute. This will ensure that thermostat is open and and ensure the fluid is circular all around of the radiator and hoses. Waite engine cool down, then open the radiator cap and check the coolant fluid level. If the level is low then add more coolant. Do not fill the coolant pass the full Mark's point. If the coolant fluid is still the same as in full mark then it is good. Continue to check the coolant fluid for next couple day. Besure that it is at the full level mark.
After you have completed work on the cooling system and you begin to replace the coolant, open the bleeder a couple turns. As you pour coolant into the reservoir air trapped will escape out the bleeder. As soon as you see coolant come out of the bleeder close the bleeder valve and continue to add coolant to the reservoir until you have reached the full mark. Replace cap on reservoir. Allow vehicle to run through a drive cycle and cool down. Top off reservoir to full mark if necessary.
If you want to simply remove the existing coolant and replace it with new, the procedure is very simple. If the cooling system needs to be flushed, do that first and then follow these steps to change coolant. 1. Uncap the coolant reservoir. Open lower drain plug. It is located on the lower edge of the radiator on the driver's side of the vehicle. Turn the plug several times to open the plug fully. It is made of plastic, so be careful when using any tools to turn it. 2. After the coolant has completely drained, close the drain plug. 3. Pour 50/50 water/coolant mix into the coolant reservoir. It will take a while for the reservoir to empty into the engine cooling system. 4. After adding approximately one gallon, start the engine. This will pull more coolant into the system. 5. Continue adding coolant until the level reaches and remains at the "full" level. 6. Cap the coolant reservoir.
Open the hood and it is on the left (passenger) side near the coolant reservoir.
Saturn's did not have a place on the radiator to fill the coolant; you'll need to look for the coolant reservoir, which was typically somewhere in front of the passenger. Note the fill level marks on the side of the reservoir; do not exceed the appropriate mark. (one for when the engine is hot, the other for when the engine is cool.) and do not open the reservoir when the engine is hot.
Open the radiator cap when engine is cool. Coolant should be right at the top. If the cooling system is healthy, the coolant reservoir will keep the system full.
You have to unlock all of your doors from INside your vehichle....can't remember off hand how...I had the same problem last night with my newly acquired jetta last night..
