I am sorry to tell you this but sure sounds like a head gasket getting weak. By year a model I am figuring you have a EJ-25 2.5 boxer motor. Not easy to really do plug test but are your plugs coming out with moisture on them? Check oil for water also. You did not mention mileage on car. If you have access to a compression tester that would be what I would test. I hope this leads you in the right direction. Sounds like you are mechanically inclined, If So, it is not a very large job to replace head gaskets. Takes more paitence than time. Subaru is the greatest company for working on your self. Prices of parts are also very easy to swallow. Good luck and have a good day.

Steam coming from right side of engine


I am not familiar with this specific vehicle. Open hood while engine is running and see where this steam is coming from. If from around the new water pump I would say bad installation. If it's coming from another area, see if bad hose, replace, or possible head gasket, repair soon, it could be as simple as a hose clamp that needs to be tightened. Only you can see this. GOOD LUCK FRIEND.

Hello. Here a non-photo diagram. Hope this helps!!!

The thermostat is located on the side of the water pump, the water pump is located just above the a/c compressor, the thermostat is fed coolant from the radiators lower radiator hose.
Thermostat :
1. drain coolant and tighten drain plug ( easier method : remove radiator cap, get big drain pan, place drain pan under lower radiator hose to radiator connection, remove clamp, slowly remove hose, allow coolant to drain into pan, now is a good time to remove radiator hose and clamp from thermostat housing )
2. remove thermostat cover / cap ( easiest to get at this when front of car is supported by jack stands and right hand side lower cover is removed ).
3. thermostat cap is held on by 3 bolts / remove thermostat.

You will notice that the thermostat's air bleed hole is pointing up and lines up with notch in water pump housing,,

ATTENTION :failure to install new thermostat in the correct location will cause engine to overheat.

1. install new thermostat to water pump, make sure air bleed hole lines up with notch, install and tighten bolts, install a new lower radiator hose, fill cooling system.

thermostat # 17670-77E00
lower radiator hose #17854-65G20
hose clamp #09401-36403
upper radiator hose # 17852-65G20

Leaking bottom radiator hose


Yes, you can do it! First, just check if the clamp on the end of the hose where it connects to radiator is just loose and needs tightening. That may be all it needs to stop the leak. When your new radiator was installed, sometimes the clamp may not have been tightened enough. If the clamp is just like a wire clamp and can't be tightened, buy a good screw clamp and fit it on. If that is not the case, you may need to pull off the lower radiator hose to investigate. Of course, to remove hose, you need to drain the radiator first. The other end of the hose goes to an inlet fitting to the water pump on the front of the engine. It will also have a clamp that you loosen or remove to pull hose off that fitting.
How it works is hot coolant in the engine is pushed by the water pump into the upper radiator hose and goes down through the radiator for cooling it and then back into the engine through the bottom radiator hose. The water pump constantly circulates the coolant through the engine to the radiator and back into the engine through the lower radiator hose.
I would bet you just have a loose fitting hose. See if you can tighten it first.

REMOVAL & INSTALLATION (4 Cyl. eng.) CAUTION
Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.
  1. Position a suitable drain pan under the radiator drain **** and drain the cooling system.
  2. On the 1MZ-FE engine, remove the air cleaner cap assembly. Be sure to label all wiring disconnected.
  3. Disconnect the water temperature switch harness from the water inlet housing (except 5S-FE engines).
  4. Remove the oil filter on 5S-FE engines. On the 1MZ-FE engines, remove the heater hose covering the housing.
  5. Loosen the hose clamp and disconnect the lower radiator hose from the water inlet housing.
  6. Remove the two nuts from the water inlet housing and remove the housing from the water pump studs.
  7. Remove the thermostat and rubber O-ring gasket from the water inlet housing. To install:
  8. Make sure all the gasket surfaces are clean. Clean the inside of the inlet housing and the radiator hose connection with a rag.
  9. Install the new rubber O-ring gasket onto the thermostat. On 2SE and 3S-FE engines, align the jiggle valve of the thermostat with the protrusion on the water inlet housing. On 5S-FE engines, align the jiggle valve with the upper side of the stud bolt. On 2VZ-FE and 3VZ-FE engines, align the jiggle valve with the stud bolt. Insert the thermostat into the housing. Fig. 1: Remove the thermostat housing from the engine with the coolant temperature sensor - 1MZ-FE engine 89553p18.jpg
    Fig. 2: Removing the thermostat from the engine - 1MZ-FE engine 89553p19.jpg
    Fig. 3: Always discard the old O-ring from the thermostat, if reusing the old component 89553p20.jpg

    Fig. 5: Line-up the jiggle valve with the protrusion on the housing - 5S-FE engine 89553g10.gif

  10. Position the water inlet housing with the thermostat over the studs on the water pump and install the two nuts. Tighten the two nuts to 78 inch lbs. (9 Nm) on 4 cyl. engines, 2VZ-FE and 3VZ-FE; 14 ft. lbs. (20 Nm) and 69 inch lbs. (8 Nm) on 1MZ-FE engines. Fig. 6: Thermostat installation - 2VZ-FE and 3VZ-FE engines 89553g11.gif
    NOTE: Don't forget to install a new O-ring onto the water inlet pipe. Apply soapy water to the O-ring prior to installation.
  11. Connect the lower radiator hose to the inlet housing and install the hose clamp. On the 3VZ-FE, tighten the bolt holding the water inlet hose to the alternator belt adjusting bar to 14 ft. lbs. (20 Nm). On the 1MZ-FE engine, tighten the bolt retaining the water inlet pipe to the cylinder head to 14 ft. lbs. (20 Nm).
  12. Attach the water temperature switch connector.
  13. On the 1MZ-FE engines, install the heater hose removed.
  14. Install the oil filter and check the oil level if removed. Install the air cleaner cap assembly on the 1MZ-FE engines.
  15. Fill the cooling system with a good brand of ethylene glycol based coolant.

How easy is it to replace the thermostat


Chrysler Full-Size Trucks 1997-2000 Repair Guide
Thermostat - REMOVAL & INSTALLATION

CAUTION NEVER open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Avoid physical contact with the coolant. Wear protective clothing and eye protection. Always drain coolant into a sealable container. Clean up spills as soon as possible. Coolant can be reused as long as it is reasonably clean and free of debris. If it appears contaminated or is more than one or two years old, it should be replaced.
WARNING Most cooling system hoses use "constant tension" hose clamps. When removing or installing, use a tool designed for servicing this type of clamp. The clamps are stamped with a letter or number on the tongue. If replacement is necessary, use only an OEM clamp with a matching ID.
CAUTION Always wear safety glasses when servicing contact tension clamps.
  1. Locate the thermostat. This is located in a housing on the engine side of the upper radiator hose for all engines except the 4.7L. On the 4.7L engine, the thermostat is located on the engine side of the lower radiator hose.
  2. Disconnect the negative battery cable (both batteries on diesels).
  3. Drain the engine coolant from the block until the level is below the thermostat.
  4. On V-10 engines, remove the support rod.
  5. On most V-6 and V-8 models, the alternator must be removed or repositioned for access to the thermostat housing.
  6. Remove the radiator hose from the thermostat housing.
  7. Disconnect any sensors fitted to the thermostat housing.
  8. Remove the retaining bolts from the thermostat housing. Note the lengths and location of each bolt for ease of installation.
  9. Remove the thermostat housing, thermostat, and gasket, if fitted.
  10. Note the relative positions of all components, especially gaskets and seals. Note the orientation of the thermostat in the housing.
To install:
  1. Be sure the new thermostat is the correct one for your engine.
  2. On V-10 engines, note that there is a rubber lip-type seal with a metal shoulder pressed into the intake manifold beneath the thermostat. The thermostat should fit snugly in the seal.
  3. Clean the gasket or seal mating surfaces.
  4. Paper gaskets must be replaced.
  5. Install the thermostat, gasket or seals.
  6. Install the thermostat housing on the engine.
NOTE The thermostat housing may have the word FRONT on it (3.9L, 5.2L, 5.9L); this goes towards the front of the vehicle.
  1. Be sure all components are properly seated before tightening.
  2. Tighten the housing bolts to 18 ft. lbs. (24 Nm). Fasteners should be tightened evenly to avoid leaks or damage.
  3. Reinstall the radiator hose onto the housing.
NOTE Ensure that you have secured the system drain plug(s) before refilling with coolant.
  1. Refill the radiator with a proper coolant mixture.
  2. Connect the negative battery cable(s).
  3. Start the engine and bleed the cooling system. Refer to "GENERAL INFORMATION AND MAINTENANCE."
  4. Ensure that the thermostat is operational (by checking the upper radiator hose for warmth), and that there are no leaks.
