I need to replace top hose in the cooling system of 1993 Tempo, top has a clamp what is the connector on the bottom?

Drain the radiator, replace the clamps & hose.refill the cooling system . top it off when running w the heat on. U might as well replace the upper hose, clamps, thermostat & gasket too just as a full cooling system maint. procedure. YES your gonna get dirty.

Be prepared to get wet. Remove the filler cap AND the plug in the top of the radiator. Undo the clamp ring on the bottom radiator hose and prise the hose off the flange. It is best to "back flush" with a hose pushed into the bottom flange (seal around with a rag) before replacing the hose and clamp.
Fill the system with new coolant through the top of the radiator then BUT NOT EARLIER, start the engine and top up via the header (expansion) tank. Check the coolant level again after running for a short distance and top up as required

Hi there,

For most Toyota radiators I know, the plug is in the center at the bottom of the radiator housing. If you cannot locate it, then simply remove the bottom radiator hose to drain the radiator. Keep in mind that you may need to replace the hose clamp if it has the one-use factory style clamp.

The drain plug is directly below your upper radiator hose at the bottom of the radiator. You can start by disconnecting the battery ground cable.

Hope this helps...

• Tools Required
• J 38185 Hose Clamp Pliers

Removal Procedure



Caution: Before servicing any electrical component, the ignition key must be in the OFF or LOCK position and all electrical loads must be OFF, unless instructed otherwise in these procedures. If a tool or equipment could easily come in contact with a live exposed electrical terminal, also disconnect the negative battery cable. Failure to follow these precautions may cause personal injury and/or damage to the vehicle or its components.

1. Remove the battery.
2. Remove the air cleaner assembly.
3. Drain the cooling system.
4. Remove the right and the left engine mount struts. Refer to the following procedures:

• Engine Mount Strut Replacement - Right
• Engine Mount Strut Replacement - Left
• Engine Mount Strut Replacement - Right
• Engine Mount Strut Replacement - Left

1. Use J 38185 to remove the inlet hose clamp from the radiator.
2. Remove the inlet hose from the radiator.
3. Remove the transmission oil cooler lines from the retainer clip at the bottom of the cooling fan shroud.

1. Remove the bolt that connects the fan shroud to the condenser hold down bracket.

1. Remove the cooling fan shroud bolts.
2. Remove the coolant reservoir hose from the radiator overflow neck.

1. Remove the radiator upper support brackets and bolts that connect to the fan shroud.
2. Disconnect the engine cooling fan motors electrical connector.
3. Remove the cooling fan motors electrical harness from the fan shroud clips.
4. Remove the cooling fan shroud.
5. Remove the bolt from the condenser tube support bracket to the radiator.
6. Use J 38185to remove the outlet hose clamp from the radiator.
7. Remove the outlet hose from the radiator.
8. Disconnect the transaxle oil cooler pipes from the radiator.
9. Tilt the top of the radiator rearward.

1. Remove the condenser hold down bracket (1) from the radiator.
2. Remove the air deflectors from the top of the radiator.
3. Lift the condenser from the mounting tabs on the radiator (2). Position the condenser aside.
4. Remove the radiator.

It comes out through the top....Make sure the engine is cold first.

• Disconnect the cooling fan electrics.
• Remove the cowling fasteners if required
• Remove the bottom hose clamp
• Remove the top hose clamp
• Open the drain tap or simply remove the lower hose.
• If the hoses are hard to remove, gently twist back and forth until they have become loose and then remove.
• Un-bolt the two radiator clamps on the top, which hold the radiator and lift it out carefully.
• When replacing it's a good idea to replace the hoses and the clamps together with a new pressure cap.

Hello, the thermostat on the Mazda Millenia is the heart of the coolant system. The thermostat regulates the flow of coolant to your motor and ensures your Mazda runs cool at all times. The thermostat acts as a valve to allow just enough coolant to flow through the system to maintain the engine temperature. When the engine temperature cools, the thermostat will close and pressurize the coolant. This cycle is what keeps your engine running cool.


To remove the thermostats follow this steps:
1. Pull the hood release latch under the steering wheel. Access the engine compartment to replace the thermostat.

2. Remove the top radiator hose by unscrewing the hose clamps with a flat-head screwdriver. The hose clamp may have a hose clamp requiring pliers. This clamp will have two tabs on it. Pull the tabs together to loosen the hose clamp.

3. Remove the bolts at the top of the thermostat assembly. The radiator hose will stop at the thermostat assembly.

4. Remove the top portion of the thermostat assembly. The thermostat will be sitting in the bottom portion.

5. Remove the thermostat with your fingers. The thermostat is positioned a particular way. Remember the position it was sitting in the housing.

And for installing the thermostats follow the following steps:

1. Place the new thermostat in the housing. Remember the position of the old one.

2. Lay down the gasket around the surface of the housing. Scrape off the old gasket with a putty knife or a razor blade.
3. Tighten the housing back together. You will want the housing snug to help create a seal for the assembly.

4. Install the radiator hose back on the assembly and the radiator. Tighten the hose clamp snug.

5. Refill the coolant level back to full. Some coolant may have been lost during the replacement.

These are the instructions for a 4 cylinder motor.

1. Disconnect the negative (-) battery cable.
   

CAUTION Do NOT remove the cylinder block or the radiator draincock with the system hot and under pressure because serious burns from coolant can occur.

1. Drain the cooling system.
   
2. Remove the hose clamps and hoses from the radiator. Remove the coolant reserve system tank-to-filler neck tube.
   
3. Remove the automatic transaxle hoses, if so equipped.
   
4. Remove the fan and fan support assembly by disconnecting the fan motor electrical wiring.
   
5. Remove the fan shroud retaining clips, located on the top and bottom of the shroud for most of the vehicles (the Dynasty has them only on the top).
   
6. Lift the shroud up and out of the bottom shroud attachment clips separating the shroud from the radiator. Avoid damaging the fan.
   
7. Remove the upper radiator mounting screws. Disconnect the engine block heater wire, if so equipped.
   
8. Remove the air conditioning condenser attaching screws located at the top front of the radiator, if the vehicle is equipped with air conditioning.
   
9. Lift the radiator free of the engine compartment.
   

Care should be taken to NOT damage the radiator cooling fins or water tubes during removal or installation.
To install:

1. Slide the radiator down into position behind the radiator support.
   
2. Attach the air conditioning condenser to the radiator, if so equipped, with a force of approximately 10 lbs. (44 N) to seat the radiator assembly lower rubber isolators in the mount holes provided.
   
3. Tighten the radiator mounting screws to 108 inch lbs. (12 Nm).
   
4. Connect the automatic transaxle hoses, if so equipped. Tighten the hose clamps to 35 inch lbs. (4 Nm).

please let me know if i can assist you in any further problems you may encounter with your vehicle.
please do not forget to rate and comment about your experience with fixya today.

There are 2 radiator hoses.They are on the bottom and the top of the radiator.Top is usually the easy one the bottom could be a little more fun.They usually come with spring type clamps and can be a little difficult to get at on the bottom one.Make sure and drain the cooling system first before removing any hose and also that the system is cooled down.You can use some channel locks to release the tension on the camps or if they are just regular clamps a flat bladed screw driver or 5/16 nut driver.You might also want to jack up the front end when doing the lower hose.Always use jack stands and work safe.All you need is a little patients.Good luck.

it is in the trunk on the left hand side, pull away the trunk carpet on left side and you will see a hole with a top and bottom screw remove the screws and pull the relay out threw the hole, then disconect the wiring connector When you plug the relay back in turn on key you should here the pump run for a few seconds if it does not then replace the relay ,or the pump.

What do you mean your top hose to the radiator is not comming to it? Are you saying that the hose is cool to the touch and not circulating fluid? If so, you're thermostat is probably stuck shut and needs replaced.
