The bleeder screw for the coolant system is on top of the motor, tword right side of the intake manifold. It should look like a nut with a flat head screw in it on a piece that goes into the motor.
There is a gold color bleeder screw on the thermostat housing. Open it up and add coolant until the fluid comes out of the bleeder screw with no bubbles. Then just tighten it back up and put the cap on.
Coolant leak.
on side of thermostat housing there is a bleed screw with engine running slowly open screw you will hear air coming out do not do this when HOT, with cool engine only , when fluid does start to come out tighten screw back in
open bleeder on engine by the upper hose outlet.
Loosen the bleed screw next to the entry point on the transmission, open the clutch master cylinder (drivers' side rear corner of the engine bay), and let it bleed. It's helpful to use a hose over the bleed screw that goes into a bottle so you can watch for bubbles. Keep an eye on the fluid level as it should drop fast. Don't pump the clutch or hold it down. The bleeding is supposed to just happen with gravity. Good luck
To bleed the coolant on a 1997 Olds Achieva, start by ensuring the engine is cool and remove the radiator cap. Next, run the engine with the heater set to maximum heat and let it idle until the thermostat opens, allowing coolant to circulate. As the coolant level drops, add more coolant to the radiator and keep an eye on the overflow reservoir. Once the coolant is circulating steadily and no more air bubbles are visible, replace the radiator cap securely.
you are wrong, you don't have a bleeder valve The system was designed to be factory filled and bled. No bleed screw. You can bleed the system but it requires dismantling the slave and master cylinders and is not recommended
If it has bleeder valves then use them to bleed the system, if not, jack up the front of the vehicle as high as possible. Remove the radiator cap and start the engine. Add coolant to keep the system full. This will allow air to escape.
a crack or a hole in the tank. or hose for that matter
On a 1997 Mercury Grand Marquis : The thread on cap on the engine coolant reservoir is your 16 PSI pressure cap / radiator cap
12.3 quarts or so says my 99gtp's manual.
It takes two people. # Suck the brake fluid out of the reservoir and replace with new fluid. # There is a bleed screw on each wheel, it looks like a grease zirk. Loosen the bleed screw and have someone push the break peddle and hold it. # Tighten the screw then they can release the breaks. # Repeat step 2-3 until the brake fluid is clean # Repeat on each wheel, refilling the break reservoir after each wheel. Do not get air in the lines either by sucking the reservoir dry or by releasing the breaks when the bleed screw is loose.
