How to replace Radiator on Audi and VW car models?

If you need dis-assembly or replacement instructions for any other auto/car part, or you want to ask question related to your car/truck jeep problem then please leave the comment with your details, so I can provide you the required instructions and solutions.

The procedure is as follows :----

Radiator

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.

1. Disconnect the negative battery cable.
2. Allow the engine to cool below 100°F (38°C).
3. Drain the coolant into a suitable container. For additional information, please refer to the following topic(s): General Information and Maintenance, Fluids and Lubricants.
4. On A4 & 1998-00 Passat models, remove the front bumper assembly. For additional information, please refer to the following topic(s): Body and Trim, Front Bumper.
5. Remove the radiator hoses from the radiator.
6. Disconnect the electrical connectors for the thermal fan switch and the electric cooling fan.
7. On models equipped with automatic transmission, if equipped, place a suitable drain pan under the fluid lines, then disconnected and plug the transmission cooling lines.
8. On 1990-97 Passat models:
1. Remove the radiator mounting fasteners.
2. Remove the upper radiator support/hood lock carrier. Outline the mounting fasteners for proper assembly.
3. Carefully lift out the radiator complete with the fan assembly.
9. On A4 & 1998-00 Passat models:
1. Remove the mounting fasteners for the power steering cooling lines and move aside without disconnecting.
2. If equipped with air conditioning:
3. Remove the left and right side air guides.
4. Remove the A/C condenser retaining clamp fasteners and retaining clamp.
5. Disconnect the A/C pressure switch just beneath the headlamp.
6. Place a suitable protective cover over the right fender, then move the condenser upward away from the retaining bracket and pivot to the side and support it at the right front wheel area using a sturdy wire loop or its equivalent. Do NOT disconnect the A/C lines from the condenser and avoid severe bending and kinking.
7. Release the upper radiator retaining bolts, pulling up and removing.
8. Tilt the radiator forward, lifting up to remove.

Fig. On A4 & 1998-00 Passat models, the upper radiator fasteners are removed by releasing the retaining bolts, then pulling up to remove

To install :

10. Installation is in reverse order of removal noting the following points:
11. Fill and bleed the cooling system with the recommended fluid and mixture ratio. The recommended engine coolant should only be diluted with distilled water.

How to replace Radiator on Acura Car models?

If you need dis-assembly or replacement instructions for any other auto/car part, or you want to ask question related to your car/truck jeep problem then please leave the comment with your details, so I can provide you the required instructions and solutions.

The procedure is as follows :---

Radiator

REMOVAL & INSTALLATION

See Figures 1 through 6

Fig. Fig. 1: View of the upper radiator hold-down bracket and bolt

Fig. Fig. 2: It may be necessary to move an A/C line out of the way for easier radiator removal

Fig. Fig. 3: Using a pair of pliers, squeeze the spring clip to remove the clamp

Fig. Fig. 4: Disengage the connector to release the wiring harness

Fig. Fig. 5: The lower radiator hose at the radiator may be hard to reach, as shown on this Integra model. If this is the case, remove the hose at the other end where it may be more accessible

Fig. Fig. 6: Thread the radiator bolts in by hand to avoid cross-threading them

1. Disconnect the negative battery cable.

CAUTION

Do not open the radiator draincock or remove the radiator cap when the cooling system is hot and under pressure. This can cause serious burns from hot, pressurized coolant. Allow a sufficient amount of time for the cooling system to cool down before opening up the system.

2. Loosen the radiator drain plug and, using a large capacity container, drain the cooling system.
3. Remove the radiator cap.
4. Disconnect the upper radiator hose.

It is recommended that each clamp be matchmarked to the hose. Observe the marks and reinstall the clamps in exactly the same position when reinstalling the radiator.

5. Remove the radiator hoses.
6. Label and disengage the wiring from the thermosensors and the electric fan assemblies.
7. For vehicles with automatic transaxles, disconnect the oil cooler lines at the radiator. Plug the transaxle ports and the hose ends to contain the fluid and prevent contamination.
8. Remove the radiator. Be careful not to damage the radiators cooling fins while removing the unit. While the radiator is not heavy, it may be awkward. Use both hands to steady it during removal and installation
9. Installation is the reverse of the removal procedure. Refill the cooling system with the proper type and amount of coolant.

You may need to bleed the air out of the system to avoid the possibility of a trapped air pocket that may cause engine overheating.
