Changed thermstat anti-freeze poured out from housing not being tight anti-freeze poured all over motor now it wont start but its turning over

1. remove cap then lower radiator hose from rad and catch in bucket/pan.THIS IS DEADLY TO ANIMALS AND WILL KILL THEM AND IT TASTES GOOD TO THEM. BE CAREFUL.
2. remove hose from housing and old housing
3. clean manifold mating surface and bolts
4. install gasket w/ sealer dab of sealer on each bolt threads
5. tighten one the other back and forth till snug
6. then tighten gently till tight.
7. fill anti freeze
8. check for leaks.

Hope this helps Mike

if the hose clamp is tight it is possibly the housing, if you squeeze the hose near where the leak is you may be able to see the coolant leaking if the hose is split or has a pin hole in it

Make sure the motor is cool you can drain down some antifreeze from radiator or slowly remove top radiator hose remove the bolts holding the housing remove housing remove thermostat clean block and housing install new o-ring or gasket which ever it has install new thermostat bolts hose re-fill radiator start let warm up check for leaks and add anti-freeze if needed.

Not a major task on your Cutlass...trace the upper radiator hose to the top of the motor...(intake manifold) you will find the thermostat inside the housing connection...held down by 2 10mm bolts...your replacement should be rated at 195 degrees...(usually the only one available for your V-6...Be sure to inspect your hoses for wear...you will lose (spill) some anti-freeze while removing the thermostat housing...I also recommend to buy a housing gasket as well as the inside gasket seal...these do not always come with the thermostat...Also use gasket sealant as no leaks are attainable...:) Have some anti-freeze handy to top off your overflow system after the installation is complete...you need to inspect while idling to be sure no leaks, and correct amount of anti-freeze in your overflow...2 measures are engine cold...and engine hot...Hope this helps...:)

You have a leak in the heater core or water build up as the dealer described to you. If it smells like anti freeze it is the heater core. If not pour a bottle of peroxide through the evaporator box which is the fiberglass housing mounted on the right side of the firewall. That has the blower motor attached to it as well. You will need to drill a small opening at one corner which will be safe to do and place a funnel in the hole drilled to add the peroxide into this housing. It will clear out all foriegn matter in the drain tube to eliminate this problem. After the peroxide sits inside this housing for 5 minutes pour one gallon of water to flushout the remaining peroxide and check if it drained thoroughly. If not repeat this process again

Jennipherbrr,

1. Make sure the car is cold. Remove the radiator cap (press & turn about 1/4 turn to remove pressure in the system) Once the pressure is bled off you can remove cap and leave it rest on the filler opening.

2. Find the petcock on the radiator (the little valve attached to the radiator. You have to open/turn clockwise to drain the anti-freeze. Drain anti freeze below thermostat housing. About 1/2 to 1 gallon.

3. Have a catch basin for the anti freeze under the car. Remove upper radiator hose from radiator and thermostat housing.

4. Remove thermostat housing from engine block (usually two or three bolts in the thermostat housing). Scrap off ALL old gasket material from engine block. Double check and make sure all gasket material is removed from surface. If not the thermostat housing will leak.

5. Install new gasket with some high temp silicone. Place a couple of dabs on the thermostat housing and gasket (the silicone is used to keep the gasket in place) *MAKE SURE YOU INSTALL the thermostat the same way you took it out. Don't over tighten the thermostat housing bolts.

6. Remove the radiator cap and replace the anti freeze you removed (make sure the anti freeze is clean). Fill the radiator to the top of the filler neck and replace the radiator cap (push and turn the radiator cap to the right- like a pill bottle). Start the car and make sure the temperture guage goes up. The guage pointer should be in the middle of the guage.

7. Check the radiator reservoir for proper anti freeze level. DO NOT OPEN THE RADIATOR CAP WHEN THE CAR IS HOT!!! THE ANTI FREEZE IS HOT AND WILL BURN YOU.

Hope this helps

Hi, First of all if there is an over heating condition going on, the 20 degree temperature out doors will not make a difference. You could have a leak and if you are able, raise the hood and check the coolant level. Do this when it is not hot. Check the plastic resevoir where you add anti-freeze or water. When it is cool, remove the radiator cap and if it is low, fill it with the required anti-freeze. Install the cap tight and start the engine and let it run. Look around the hoses for water leaks, and take a look under the auto for water pouring out and you will know if you have a leak by the amount of anti-freeze you added and if you see it leaking. With the gauge reading hot, and the engine starting to misfire, this is not a good sign. This can and will cause the engine to freeze up!! You can blow a head gasket, crack the block and do much internal damage to this engine. I know as This just happened to my daughter a while back, it was over heating and she didnt no it and didnt see that the heat gauge was buried on hot. It locked up the motor from this and I had to spring for a new engine. She said she only noticed it missing and loosing power. So, check the hoses, radiator, turn the heater on when its warm to see if the hoses are leaking. Try and refrain from driving it if it is over heating this fast. You may have a thermostat that is closed shut. You don't want to blow this motor up!! If you find a hose leaking and you can change it yourself, great. If you see no leaks, its time to have it towed to a shop. This is your best solution, as you dont want to loose the motor. Keep me posted on what you find. Best of Luck to you,
Sincerely,

1. Write down your radio code if it has some anti-theft device.
2. Allow the engine to cool down for about 3-hours before the start of this operation.
3. Open the hood, and disconnect the battery negative terminal. Tuck the negative terminal aside so it won't flip back.
4. Locate the radiator drain-plug (plastic wing-nut) on the lower back side of the radiator, and turn it backward to remove it.
5. Place a container under the radiator to catch the anti-freeze coolant.
6. Remove the radiator cap.
7. Once the coolant is drained, trace the upper radiator hose to where it ends on the engine(thermostat housing), and remove the hose with a medium size plier.
8. Loosen the three bolts holding the thermostat housing. Gently take out the housing.
9. Notice the position the thermostat was previously installed.
10. Replace the old thermostat, and the o-ring around it. Clean its mounting area. Notice that the o-ring fits around the thermostat.
11. Replace the thermostat housing and torque the three bolts to 78-inch pounds. Replace the upper hose.
12. Replace the radiator drain-plug.
13. Re-use the antifreeze coolant and be careful no dirt goes in with the coolant into the radiator.
14. Return the radiator cap.
15. Reconnect the negative battery terminal.
16. Start the car and check for leak.

Important: Anti-freeze coolant harmful to the environment. Return unwanted anti-freeze coolant to collection areas.

Change the oil & filter. you may have to due a second oil change after running the car if the oil still looks like a milkshake.

sounds like the starter, i dont think its siezed the motor in that short distance. try and hit the starter with a hammer or something with someone turning the key at the same time, it should start with acouple trys. if it does than u need a new starter.
