If it's stuck on there that tightly, chances are the hose is dried out. On ones like that, just cut it off as near to the top of the nipple as you can and then remove what's left. You should have enough slack in the hose to just put it back on when you've finished whatever you are doing.

My 1998 S10 Chevy pick up heater only heats when I hold the gas pedal to the floor. When I let off the gas it slowly starts blowing cold air again. what is your thoughts on this problem?


Sounds like you have a restriction in the heater core. You can try removing the heater hoses at the firewall and putting a garden hose to the bottom inlet to reverse flush the core, if this is unsuccessful you will probably need to have the core replaced.

On my 92 toyota pickup some years ago the heater control valve was leaking so I removed the hoses and capped off the pipe from the water pump, now i need the return heater hose pipe location


you blanked of the heater off and now want to reconnect the system

depends on which motor is fitted ..get back to this question with the engine fitted in your 92

will start with this engine .......1992 pickup with a 22re
The part labeled "3" is the heater valve - it links to the hot/cold lever inside the cab and controls how much hot water flows through the heater core. Therefore, this hose - "2" ( blue line) is the "heater core inlet hose". The hose numbered "1" (red line) is the outlet hose.

How to back flush heater core 2007 grand prix


drain coolant system locate heater cores hoses going through firewall you need to buy the radiator flush kit at any auto parts stores. remove heater cores hoses from one end or buy extra long heater hoses same size as heater core hoses in vechicle at auto parts store use the flush kit when you flush through one of the heater core hoses let the other hose drain in a drain pan when you use home garden hose use low water pressure dont use garden hose to the max or you will rupture heater core. your best bet let radiator shop flush whole coolant system. because heater cores hoses are in a tight spot.make sure engine off if you just going to flush out heater core only .after flushing heater core good time to replace heater core hoses.if job too hard or complicated let radiator shop flush out radiator the engine block and heater core because if radiator stopped up or engine block stopped up the gunk and rust will reenter plug up heater core.if you tight on money you can flush out your own radiator.drain out radiator using large drain pan. remove top radiator hose and remove bottom radiator hoses connect to water pump.use garden hose with flush kit part with water pressure not too high put garden hose to top radiator hose run water until clear water run out bottom radiator hose in drain pan,the flush out engine block remove thermostat.if you had another spare thermostat housing with RTV SILICONE SEALANT THAT HAS SET UP INSTALL THERMOSTAT HOUSING BACK TO ENGINE WITHOUT THERMOSTAT FLUSH OUT THE ENGINE BLOCK, WHEN DONE INSTALL NEW THERMOSTAT THEN INSTALL ORIGINAL THERMOSTAT HOUSING WITH NEW ORING WHICH YOU BUY AT DEALERSHIP.IF ALL SOUND COMPLICATED LET RADIATOR SHOP FLUSH OUT COOLANT SYSTEM.

Is the thermostat located where the LOWER radiator hose meets the block, not the upper? 4 cylider 2.4 engine


The thermostat on '94 SE-V6, and the thermostat is where the lower radiator hose contacts the block (on most cars and trucks they seem to be on the upper hose). You have to do a little bit of digging to get to it: i.e. taking off the pulley bracket and a few wires, the fan shroud, and most likely the upper radiator hose as well. It kindof sucks. Good luck.

Where would the screw or nut be on the oil pan of a 1995 crown vic be to drain the old oil


Oil Pan - REMOVAL & INSTALLATION

4.6L Engine
If your vehicle is equipped with air conditioning, refer to General Informatcion and Maintenance for information regarding the implications of servicing your A/C system yourself. Only a MVAC-trained, EPA-certified, automotive technician should service the A/C system or its components.
  1. Have the A/C system recovered by a MVAC-trained, EPA-certified, automotive technician.
  2. Disconnect the battery cables, negative cable first, and remove the air inlet tube.
  3. Relieve the fuel system pressure and disconnect the fuel lines; Drain the cooling system and remove the cooling fan and shroud.
CAUTION When draining the coolant, keep in mind that cats and dogs are attracted by the ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.
  1. Remove the upper radiator hose. Remove the wiper module and support bracket.
  2. Disconnect and plug the compressor outlet hose at the compressor and remove the bolt retaining the hose assembly to the right coil bracket. Cap the compressor outlet.
  3. Remove the engine harness connector from the retaining bracket on the brake vacuum booster and detach the connector and transmission harness connector.
  4. Disconnect the throttle valve cable from the throttle body and disconnect the heater outlet hose.
  5. Remove the nut retaining the ground strap to the right cylinder head. Remove the upper stud and loosen the lower bolt retaining the heater outlet hose to the right cylinder head and position out of the way.
  6. Remove the blower motor resistor. Remove the bolt retaining the right engine mount to the lower engine bracket.
  7. Disconnect the vacuum hoses from the EGR valve and tube. Remove the 2 bolts retaining the EGR valve to the intake manifold.
  8. Raise and safely support the vehicle. Drain the crankcase and remove the engine mount through bolts.
  9. Remove the EGR tube line nut from the right exhaust manifold and remove the EGR valve and tube assembly.
  10. Disconnect the exhaust from the exhaust manifolds. Lower the exhaust system and support it with wire from the crossmember.
  11. Position a jack and a block of wood under the oil pan, rearward of the oil drain hole. Raise the engine approximately 4 in. and insert 2 wood blocks approximately 2 1 / 2 in. thick under each engine mount. Lower the engine onto the wood blocks and remove the jack.
  12. Remove the 16 bolts retaining the oil pan to the engine block and remove the oil pan.
It may be necessary to loosen, but not remove, the 2 nuts on the rear transmission mount and with a jack, raise the transmission extension housing slightly to remove the pan.
  1. If necessary, remove the 2 bolts retaining the oil pickup tube to the oil pump and remove the bolt retaining the pickup tube to the main bearing stud spacer. Remove the pickup tube.
See Figures 1, 2 and 3

To install:

  1. Clean the oil pan and inspect for damage. Clean the sealing surfaces of the front cover and engine block. Clean and inspect the oil pickup tube and replace the O-ring.
  2. If removed, position the oil pickup tube on the oil pump and hand start the 2 bolts. Install the bolt retaining the pickup tube to the main bearing stud spacer hand tight.
  3. Tighten the pickup tube-to-oil pump bolts to 6-9 ft. lbs. (8-12 Nm), then tighten the pickup tube-to-main bearing stud spacer bolt to 15-22 ft. lbs. (20-30 Nm).
  4. Position a new gasket on the oil pan. Apply silicone sealer to where the front cover meets the cylinder block and rear seal retainer meets the cylinder block. Position the oil pan on the engine and install the bolts. Tighten the bolts, in sequence, to 15-22 ft. lbs. (20-30 Nm).
  5. Position the jack and wood block under the oil pan, rearward of the oil drain hole, and raise the engine enough to remove the wood blocks. Lower the engine and remove the jack.
  6. Install the engine mount through bolts and tighten to 15-22 ft. lbs. (20-30 Nm).
  7. Position the EGR valve and tube assembly in the vehicle and connect to the exhaust manifold. Tighten the line nut to 26-33 ft. lbs. (35-45 Nm).
Loosen the line nut at the EGR valve prior to installing the assembly into the vehicle. This will allow enough movement to align the EGR valve retaining bolts.
  1. Cut the wire and position the exhaust system to the manifolds. Install the 4 nuts and tighten to 20-30 ft. lbs. (27-41 Nm). Make sure the exhaust system clears the crossmember. Adjust as necessary.

Tighten the EGR tube line nut at the EGR valve to 26-33 ft. lbs. (35-45 Nm). Connect the vacuum hoses to the EGR valve and tube.
  5. Install the blower motor resistor. Position the heater outlet hose, install the upper stud and tighten the upper and lower bolts to 15-22 ft. lbs. (20-30 Nm). Install the ground ******** the stud and tighten to 15-22 ft. lbs. (20-30 Nm).
  6. Connect the heater outlet hose and the throttle valve cable. If necessary, adjust the throttle valve cable.
  7. Attach the engine connector and transmission harness connector. Install the harness connector on the brake vacuum booster.
  8. Connect the air conditioning compressor outlet hose to the compressor and install the bolt retaining the hose to the right coil bracket.
  9. Install the upper radiator hose and connect the fuel lines. Install the wiper module and retaining bracket.
  10. Install the cooling fan and shroud and fill the cooling system. Fill the crankcase with the proper type and quantity of engine oil.
  11. Connect the negative battery cable and install the air inlet tube. Start the engine and check for leaks.
  12. Have a MVAC-trained, EPA-certified, automotive technician evacuate and recharge the air conditioning system.

Hope this helps (remember to rate this helps).

Replace thermostat. Engine temperature gauge hardly moves and heat into passenger compartment luke warm. Unable to locate thermostat in engine compartment.


The thermostat is where your lower radiator hose meets the engine block. There are three bolts to remove to get to it, if your engine is a V6

1998 Buick LeSabre 3800 V6. Coolant is leaking fro an "L" shaped hose that leads from the engine block to other heater hoses. Is this a major repair or can i do it myself?


My guess is you can fix it yourself if you posses rudimentary repair skills. Dump the radiator. Remove the hose, Take to parts store. Try to describe to them. Take a picture beforehand, just in case. Replace hose, refill radiator. Start engine, put heater on high, top off radiator again, close radiator, check for leaks, that's it. If you are really cautious then you will fill with all water first, check for leaks, dump and refill with proper antifreeze/water mix.

Jaguar 1999 s-type 3.0 V6 heater problem. The heater is blowing cold unless the engine rev's are held above 1500, any idea's about what the cause could be?


you either have a restriction in the cooling system like maybe a restricted heater core or the water pump impellers are corroded and no blades are left. Only way to tell is to remove the water pump and inspect then replace it since its off.
Or remove the heater core hoses and blow thru.
If anyone ever put a stop leak in the radiator this can cause blocked lines.
