Question about Cars & Trucks

Open Question

98 subaru legacy outback is making a whining noise, smoking and smells like anti freeze. Bad radiator or water pump?

Car is fine while it is idling but as soon as you drive it, the car overheats, makes a whining noise, smokes, and starts to throw cold air. I replaced the thermostat and bled the air out of the radiator, but still have the same issues. When the car smokes it smells like coolant and the smokes comes from the drivers side of the radiator. The cooling fans kick on and run.

SOURCE: car overheats. have replaced radiator,thermostat.water

Question that I pose is:
Is the car overheating or are you assuming it is as the gauge is telling you that it is?
There are two cheap and simple things that are not mentioned in this post. There is an Engine coolant temp sensor which in all of their innane wisdom Saturn built with a plastic tip and we all know plastic melts fairly easily. This part is a simple fix as it needs a 13mm deep socket and that is it for tools to replace it and it is $10 - $15 for a new on with a copper tip. There is also an Engine coolant temp switch which sends information to the PCM to tell the gauge what the reading should be. Aslo $10 - $15 and a 13MM deep socket to replace. These are common issues with the S Series Saturns. I do however recomend that if you are going to replace them yourself that you empty the radiator of coolant as the sensor and switch are directly in the engine block coolant flow and will give you a nice little shower if you do not at least jack the drivers side up before replacing them.

SOURCE: '90 Subaru Legacy overheating....

cool air and overheating point to low coolant level. Do you have a bleeder valve near the thermostat? You may have air trapped in the system. If no air trapped, the radiator may be plugged up not allowing proper circulation of coolant.

Flushing the cooling system has its drawbacks. I you needed one freeze plug, you can reasonably suspect the others are surely right close to failure.In this case, starting to fail one at a rime weakest first. Now, as far as the other issues are concerned. What is the question? Sounds like the tazmanian devil had too much time on hand. I don't know the qualifications or integrity of your mechanic, but I do know a reputable, as well asa professional mechanic is not likely to intentionally or even bother to, contribute to these describe issues. Ocassional blue smoke is an internal problem, The AC is an issue in itself, The caalyctic converter is an issue that is too messy, smrlly thing to deal with. Any evisence of how and of what it was gutted? What was repaired or listed as repaired on your invoice? And what state are you in? It appears you may be seeking legal advice and in this forum it would not be an appropriate place to seek it. You may want to refer this to an Attorney for assistance.. Good luck and I hope you reach some resolve on this matter.

SOURCE: OVERHEATING!!!!

Since you changed your waterpump, you need to do an air bleed...
This is INSANELY important!
The airbleed is mounted on the top of the radiator on the passenger side.
Its made of plastic, has a seal, and looks like a 1/2 inch (12mm) philips screw head.
To do this, make sure the engine is cold and not running.
Use a large FLAT HEAD screw driver and turn it counter clockwise.
It might be very tight, so be prepared for a bit of torque to turn it!
Unscrew it, and look in the hole.
Coolant should be at the top of the bottom of the screw hole.
It should be low, so add coolant to the open hole.
While doing this, be sure the radiator cap is off so you can balance the fluid level properly.
Why do you need to bleed the system?
The engine has a slight tilt upwards toward the radiator, and both your waterpump, and block will have a tendancy to leave air near the top of the block and heads.
This is a common mistake on several makes after a coolant change.
Make sure all fluids are topped off, fill the overflow tank to its max level indicated on the tank itself and your done.
Provided you havent been driving long on the car in this condition, it shouldnt blow a headgasket.
A good way to know if the headgasket is bad is the radiator cap will have a brownish "slime" indicating combustion gasses are getting into the cooling system.
IF this is the case, your engine is pumping combustion gasses into your system and no amount of air bleeding with help.
Another tell tale sign of coolant being pressurized, is a overflowing "overflow" tank, and a sudden blast from Normal operating temprature to HOT, and then suddenly.. it goes back to Normal again.
There is usually a "gurgling" sound under your dash..
Lets assume you just need to do an air bleed, and things will go back to normal.
Also, if your airbleed screw has alittle coolant leaking around it, replace it with a new one as the seal and plastic have worn due to age.
Good luck!

My 1997 subaru impreza squeals badly and then engine smokes


Hi this sounds weird does the smoke come out from the front engine covers? the squealing could be the cambelt trying to turn a semi or completly ceased waterpump which would cause the smoke after a while, also without the waterpump working properly the engine will leak water and anti freeze out the overflow and overheat really quickly

The heater just quit working. It worked fine yesterday but this morning it does not. The car is running a little hotter trhan normal but not overheating. Any ideas?


I would check to make sure the radiator is full and the overflow tank is filled to the proper level. It doesn't have to be very low for these cars to stop blowing heat.

Loping idle with a '98 Subauru 2.5


This usually happens when the fuel pump is loosing pressure.

I will just advice you make a replacement on the fuel pump. It is located in the fuel tank beneath the back seat.

Be sure to consider the rating on the fuel pump when replacing.

Good luck and rate my solution.

1995 Subaru Legacy Wagon Radiator


Hi sir, if you want to do a proper job here's how.
  1. Get radiator flush let you car Idle for a while or drive for 15 min.
  2. Let Car cool Down
  3. If no drain PLug remove the hose at the bottom this is the same pipe going into your water pump, Work gentle with it try not to damage the pipe.
  4. open your rediator cap, this will allow the water to train from radiator.
What about all the dirty water inside the engine? this is how to do a decent flush.

  • The car should be cold
  • remove the water pipe at the top of the radiator
  • take your garden hose and insert it to the rediator don't force it just hold it there.
  • Start the car let it idle, open the hose pipe.
What happens now is that the water pump pulls all the clean water trough the rediator and pushes all the dirty water out the other side.
  • when water is clear turn off water
  • kill engine
  • Tighten water hose
  • refill with good Anti freeze anti boil and top op with water
  • drive the car till hot
  • check for any leaks on the pipes you removed before
Hope this Helps
