I take it this only happens when the vehicle is stopped & idling? If not, check radiator & hoses for blockage (since you've already replaced the thermostat & top hose) - repair/replace as needed. Next, check the coolant temperature sensor's operation (there are two sensors - one for the temp gauge on the instrument panel, the other is used by the ECM (PCM). If that one is malfunctioning (i.e., telling the computer that the engine coolant temperature is less than it actually is, The ECM (PCM) it won't turn on the cooling fans.
Since you didn't specify which engine you have (i.e., 2.4, 2.6 or 3.5), Photo locations of all three are included here.

Look for coolant bleed screws, sounds like air trapped in the system...Check your owners manual for directions on filling, and be sure the have the heater temp control on full hot, when refilling coolant....

You may have to change the termostat again. 1in 5 are defective. Also even if the water pump is not leaking it may not be pumping due to a loose impeler. OPen rad cap when cool start engine you should be able to see fluid circulating. No move ment ,change water pump.

I changed my thermostat but that radiator symbol still comes on for my 2004 kia Amanti. When you replace the antifreeze do have to prime it someway brcause it doesn't seem to flow like it should.


I've dealt with this vapor-lock issue in multiple ways. One was to put an aspirin in the thermostat to hold it open. When disolved it would work properly. But want it open for a bit so that coolant can flow.
The other was to squeeze the radiator hoses to push coolant and work air into radiator so it could come to top of radiator. Another is to simply run it till warms up, shut it down and ad coolant to the reservoir.

2001 A4 thermostat location


Hello! Ignore my request regarding the engine size, The thermostat is well hidden..Standard labor to replace is 2.0 hours...Thermostat is part # 06B-121-111-G....
Step 1: Drain coolant...

Remove bottom belly pan... Remove coolant reservior tank cap... Remove plastic clip holding coolant sensor in place at lower radiator hose/pipe... With bucket/catch pan underneath, remove sensor and let coolant drain...


Step 2: Remove upper radiator hose...

Remove the small hose connecting the coolant reservoir to the upper radiator hose... Then remove the larger hose from the hard pipe running along the intake and from the radiator... You'll need to pop up (but not off) the metal clip holding the hose to the radiator, then firmly pull back..

Step 3: Remove intake hose (throttle body to inter-cooler)...

Remove driver's side headlight (not necessary but makes it a lot easier). Loosen clamp at each end and remove hose...

Step 4: Remove throttle body...

Remove electrical connector and 4 hex bolts (5mm)...

Step 5: Loosen serpentine belt and slip off of alternator...

Use a box-end or adjustable wrench on tensioner, pull to the right... Carefully slip belt off alternator (towards front of car). Allow to hang loose below...

Step 6: Remove alternator bolts...

Remove 4 bolts holding alternator to bracket...

Step 8: Remove vertical support piece from intake manifold to block...

Remove the two bolts holding the support piece (6mm hex)...

Step 9: Remove bolt from metal hose on thermostat; remove bolt from top of oil cooler...

This will allow you to move the hard pipe away from thermostat... Then wiggle it free from the pipe afterwards...

Bolt holding the hard pipe on the right, two bolts holding the thermostat to the block on the left...

Step 10: Remove upper and lower hoses from t-stat. Remove electrical connector on back side...

Step 11: Remove 2 bolts holding thermostat to block, and remove thermostat...See photo below...Guru...Saailer

There is a cooling fan switch normally located near the thermostat housing or in the head near the thermostat housing. check this and see if it is defective.
