With a 1993 it is likely a hose that is leaking. You need to start the engine after filling up the radiator (through the cap that says never open when hot) Bring the car up to operating temperature and find the source of the leak. Hoses are easy to replace they cannot be repaired. remove the clamp on both ends of the leaking hose and pull the hose off. replace with the clamps loose and tighten them down refill the radiator and you're good to go. In the off chance it's not a hose you'll have to take the car into a shop to have it fixed.

My Alero is overheating, and pushing the coolant out the surg tank, my brother said water pump, changed. then said thermostat, changed. then said radiator clogged, flushed. still doing the same thing?

Do fans come on , if not it is the $8 dollar temp sensor or the fan fuse or the fan motor.
If you have heat from the heater and if radiator gets hot then it is neither the raditor or the water pump nor the thermostat as neither heater or radiator would get hot
because no water would be moving in the system.

Coolant in oil

Some place the coolant flows is through an area with oil in it, and the 2 mix, this indicates the gasket is defective or the part is cracked or otherwise not sealing. Cylinder head gaskets can cause this and often do.

Water leak by the front of the transmision

I had the same symptom and it turned out to be the small metal tube ($5 part) off the back of the water pump that feeds the coolant line that lays in the valley under the intake plenum. When the valley fills with coolant/water it spills off the back of the motor down the front of the trans. To fix the problem you need to remove the entire intake, fuel rails and plenum (took me 2 days to R&R plus acquire the parts) to get to the problem. I suggest you replace the water pump at the same time while you're in there. Not a hard job just lots of bending over wrenching. The shop wanted $1500, I had $500 into parts including plugs, alternater, water pump, belts, coolant and hoses. Good luck.

I dropped a piece of plastic in the oil fee, i was wondering how i can get it out?

I'll assume that you dropped something in the oil fill tube while refilling the sump.If the fill tube is connected to a valve cover your oil drains could be plugged. If the piece is large or hard enough it could get between the coils of a valve spring and bind. So you need to remove the valve cover and remove the plastic. You might find it at the base of the fill tube if it has a deflector. If it is not in the rocker box or the fill tube it most likely went down one of the return drains. You'll need to ensure the drains are free of any obstructions. The drain is located at a lower corner of the rocker box. If the plastic passed to the sump or lifter valley via a pushrod tube I would leave it. It it traveled either of those routes its quite likely harmless.

My son's car overheated. Went to get some anti

The overheating is caused by the sludge. It is very easy to correct this problem. Remove the radiator cap and open the drain valve at the bottom of radiator. If possible, remove the reservoir and flush out with water. Make sure to get all sludge out of reservoir, then reinstall. Once the radiator stops draining, insert water hose (without nozzle) and turn water on. Keep the drain valve open. Run water through radiator until it runs clear. Once it runs clear, start the engine and let it run while keeping the water running through radiator. Allow engine to run until the thermostat opens up. Continue running water through radiator with engine running until the water from drain runs clear. Once you have done that, turn off the engine. Close the drain valve and refill radiator with proper mixture of coolant and water. Once radiator is filled, start engine and let circulate through engine. Coolant level will drop as the coolant starts circulating. Shut off engine and top off radiator. Fill the reservoir with the required amount of coolant. Testing the coolant at least once a year will help prevent this from happening again. Coolant should be replace a minimum of five years, less if coolant bottle specifies.

Your fuel filter housing sits in the engine valley, there is a drain valve on it also has a fuel pressure regulator, may be leaking at one of these points or the hose going into the housing from the tank. Take the cover off that says POWERSTROKE on it, start the vehicle,, get a mechanics mirroer. you may be able to see where it is leaking . Hope this is helpful

How do you replace the coolant on a 2006 mini cooper

this is how i replace the coolant on minis. remove the lower splash shield and disconnect the lower radiator hose right off the radiator. when it stops draining, resecure the hose and clamp. next , ur going to have to refill and bleed the cooling system.i do this through the coolant resevroir. this is important, or else ur vehicle is going to overheat and boil over no matter if the system is full or not. there are 2 coolant bleeder valves. open both valves a little and fill the coolant system with the correct coolant. fill the coolant. fill the coolant till it begins to come out of the 2 valves . when coolant begins to come out through the valves slowly and steady with no air pockets , go ahead and close up both valves and run vehicle to normal operateing temps, make sure vehicle isnt overheating and u should be fine. u may have to repeat the procedure over again. once u do it once u remember how next time. ( the two bleeder valves are sort of hard to explain in words where they are, they arent hard to access ) u can turn them with a flathead screwdriver) they are usually black and plastic.
