Hi,
I think you are referring to the radiator hose. There is one at the top of your radiator and one at the bottom.
It sounds like you had a build-up of pressure from overheating, which caused your hose to come off.
A major culprit for this is a sticking thermostat. If the thermostat does not allow coolant to flow through then engine, it will overheat quickly. This is not good for your engine. I would replace the thermostat. It is inside of a housing on your engine, which the top radiator hose is connected to. Be sure to get a new gasket for the housing.
I hope this helps... Good luck!

My 1999 dodge caravan is still overheating. I have already replaced the thermostat and the water pump, also there is no heat. please help me someone!


Hi there.
Well you can either have a problem with either radiator outer {dust/dirt in outer core of radiator or clogged up inside were water goes, or soft hoses,blowen head gasket plus a few others ,but first go to garage to were you blow up your tyres and use the air hose and blow out the radiator core where the air goes in, 2 drain out radiator water and then refill with water at 1 ltr at a time and then check your info car book and find how much water the radiator takes ,if it dosent take all the ltrs then the radiator is blocked inside.
if engine runs rough missing etc then get your Head gasket checked out.
When you say no heat is that with heat on gauge or no heat from heater, as it could be heater blockage same as radiator core. So let me know how you get on.

1990 BMW 525i 2.5L engine overheats after rplaceing water pump, stermostat,fan clucth,radiator


There's trapped air in the cooling system.
  • You need to remove the bleeder screw on top of the radiator when adding water to the expansion tank.
  • With the engine running, pour water into the expansion tank till you see air go out through the bleeder screw's hole.
  • Just keep adding water until no more air bubbles come out then just put the screw back in place.
  • Then fill the expansion tank to it's normal level/line.

My 99 alero v6 is over heating not leaking ight mite be hoses or thermostat . or head gasket but when it overb heats the smoke comes from the top of the engine


REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP.IF CAR OVER HEATING WHILE IN MOTION.MORE LIKELY ITS THE THERMOSTAT,LOW COOLANT IN RADIATOR OR COOLANT SYSTEM,BAD WATER PUMP,WATER PUMP WEEP HOLE IS LEAKING, WATER PUMP NEEDS REPLACING.CHECK ENGINE OIL,IF OIL LOOKS LIKE MILK SHAKE YOU HAVE LEAKING HEAD GASKET.IF CAR IN PARK AND OVER HEATS WHILE IN A LONG TRAFFIC LINE OR.BANK DRIVE THROUGH COOLANT FAN NOT TURNING ON, BECAUSE THE ENGINE COOLANT TEMPERATURE SENSOR FAULTY.CODE SCAN CAR FOR FAULTY COOLANT FAN RELAY OR FAULTY PCM. CHECK COOLANT FAN FUSE, AND HOT WIRE THE COOLANT FAN TO MAKE SURE ITS WORKING.IF COOLANT FAN DONT WORK WHEN HOT WIRED. COOLANT FAN NEEDS REPLACING. REPLACE BOTH RADIATOR HOSES, REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP.BUY NEW COOLANT ADD 50/50 WATER AND COOLANT.IF ENGINE OIL HAS ANTIFREEZE IN IT.REPLACE ENGINE OIL AND OIL FILTER TO KEEP FROM LOCKING UP THE ENGINE.GET CAR FIX.DONT KEEP DRIVING IF IT KEEP OVER HEATING,ENGINE DAMAGE WILL OCCUR.I HOPE INFORMATION I GAVE YOU WILL FIX PROBLEM.PROBLEM COULD BE LEAKING RADIATOR HOSES BUT CHANGE THERMOSTAT THATS FIRST THING I WOULD CHANGE BECAUSE IF IT CLOSED, ENGINE WILL OVER HEAT AND CRACK CYLINDER HEAD OR CRACK PISTON, COOLANT NEED TO CIRCULATE THROUGH THE ENGINE TO TAKE AWAY THE HEAT FROM ENGINE.

Hello vocalviixen,

The pipe that you referred to is the exhaust crossover pipe. Below I've included removal and installation instructions.

Also, the procedure for bleeding the coolant system is critical; if you need those instructions please post the question.

REMOVAL PROCEDURE
1. Disconnect the battery ground (negative) cable.
2. Remove the throttle body air inlet duct.
3. Drain the coolant from the cooling system.
4. Remove the inlet radiator hose from the engine.
5. Remove the thermostat bypass pipe.
6. Remove the exhaust crossover heat shield bolts.
7. Remove the exhaust crossover heat shield.
8. Remove the exhaust crossover pipe studs/nuts.
9. Remove the exhaust crossover pipe.
INSTALLATION PROCEDURE
1. Install the exhaust crossover pipe.
2. Install the exhaust crossover pipe studs/nuts.
3. Tighten the exhaust crossover pipe studs/nuts to 18 lb ft.
4. Install the exhaust crossover heat shield.
5. Install the exhaust crossover heat shield bolts.
6. Tighten the exhaust crossover heat shield bolts to 89 lb in.
7. Install the thermostat bypass pipe.
8. Install the inlet radiator hose to the engine.
9. Fill the cooling system with engine coolant.
10. Install the throttle body air inlet duct.

How do I replace a water pump on a 1999 malibou with a quad 4?


Water Pump 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. 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. 2.4L Engine
  1. Disconnect the negative battery cable
  2. Detach the Oxygen (O2) sensor electrical connector.
  3. Properly drain the engine coolant into a suitable container. Remove the heater hose from the thermostat housing for a more complete coolant drain.
  4. Remove upper exhaust manifold heat shield.
  5. Remove the bolt that attaches the exhaust manifold brace to the manifold.
  6. Remove the lower exhaust manifold heat shield.
  7. Break the manifold-to-exhaust pipe spring loaded bolts loose using a 13mm box wrench.
  8. Raise and safely support the vehicle. NOTE: It is necessary to relieve the spring pressure from 1 bolt prior to removing the second bolt. If the spring pressure is not relieved, it will cause the exhaust pipe to twist and bind up the bolt as it is removed.
  9. Unfasten the two radiator outlet pipe-to-water pump cover bolts.
  10. Remove the manifold to exhaust pipe bolts from the exhaust pipe flange as follows:
    1. Unscrew either bolt clockwise 4 turns.
    2. Remove the other bolt.
    3. Remove the first bolt. NOTE: DO NOT rotate the flex coupling more than 4°or damage may occur.
  11. Pull down and back on the exhaust pipe to disengage it from the exhaust manifold bolts.
  12. Remove the radiator outlet pipe from the oil pan and transaxle. Leave the lower radiator hose attached and pull down on the outlet pipe to remove it from the water pump. Leave the radiator outlet pipe hang.
  13. Carefully lower the vehicle.
  14. Unfasten the exhaust manifold-to-cylinder head retaining nuts, then remove the exhaust manifold, seals and gaskets.
  15. Remove the front timing chain cover and the chain tensioner. For details, please refer to the procedure located later in this section.
  16. Unfasten the water pump-to-cylinder block bolts. Remove the water pump-to-timing chain housing nuts. Remove the water pump and cover mounting bolts and nuts. Remove the water pump and cover as an assembly, then separate the two pieces. Fig. 1: Water pump and cover mounting - 2.4L engine 87953070.gif
    To install:
  17. Thoroughly clean and dry all mounting surfaces, bolts and bolt holes. Using a new gasket, install the water pump to the cover and tighten the bolts finger-tight.
  18. Lubricate the splines of the water pump with clean grease and install the assembly to the engine using new gaskets. Install the mounting bolts and nuts finger-tight.
  19. Lubricate the radiator outlet pipe O-ring with antifreeze and slide the pipe onto the water pump cover. Install the bolts finger-tight.
  20. With all gaps closed, tighten the bolts, in the following sequence, to the proper values:
    1. Pump assembly-to-chain housing nuts:19 ft. lbs. (26 Nm).
    2. Pump cover-to-pump assembly: 106 inch lbs. (12 Nm).
    3. Cover-to-block, bottom bolt first: 19 ft. lbs. (26 Nm).
    4. Radiator outlet pipe assembly-to-pump cover: 125 inch lbs. (14 Nm).
  21. Using new gaskets, install the exhaust manifold. Make sure to following the tightening sequence and torque specifications given in the exhaust manifold procedure located in this section.
  22. Raise and safely support the vehicle.
  23. Index the exhaust manifold bolts into the exhaust pipe flange.
  24. Connect the exhaust pipe to the manifold. Install the exhaust pipe flange bolts evenly and gradually to avoid binding. Turn the bolts in until fully seated.
  25. Connect the radiator outlet pipe to the transaxle and oil pan.
  26. Install the timing chain tensioner and front cover.
  27. Install the lower heat shield.
  28. Carefully lower the vehicle.
  29. Fasten the bolt that attaches the exhaust manifold brace to the manifold.
  30. Tighten the manifold-to-exhaust pipe nuts to specification.
  31. Install the upper heat shield.
  32. Attach the oxygen sensor connector.
  33. Fill the radiator with coolant until it comes out the heater hose outlet at the thermostat housing. Then connect the heater hose. Leave the radiator cap off.
  34. Connect the negative battery cable, then start the engine. Run the vehicle until the thermostat opens, fill the radiator and recovery tank to their proper levels, then turn the engine OFF.
  35. Once the vehicle has cooled, recheck the coolant level, then install the radiator cap.

HEAT PROBLEM ON 3Y TOYOTA ENGINE


There is a separate T-piece 3way thermostat made by BMW for the old box shaped 318i and 518i cars. It is a separate unit that fits into the water pipes, and not onto the engine. It has a hot water inlet, and a hot water to radiator outlet, and an engine warming outlet. Each outlet has a thermostat. The radiator on opens when the water is hot, and the engine warming closes when the water gets too hot. The temp stays at 85 D Celsius all the time. Works well on my vw synchco bus and subaru 2.5 engine.

Ord galaxy 1998 tdi 110 radiator over heating but


you need to flush the radiator out.
With the engine cold, remove coolant bottle cap to release pressure.
Drain engine coolant from drain plug on radiator.
With the drain plug removed disconnect the highest hose connected to a radiator.
use an hosepipe and put it in place of the disconnected radiator pipe.
turn on the water to the hose pipe and let it flush out any sludge accumulated in the radiator. after a few minutes turn off water supply, reconnect radiator hose and drain plug and refil using recommended coolant mix for your galaxy (purchased at most autofactors and garages).
Also check your thermostat as if this is faulty it would stop the flow of coolant running around your engine.

hope this helps
