Hi!

Can someone please help find the right source for this part 89428-33010. Lexus dealer here at NC is charging me 112.00 for this part. So i decided to find one online and found this 15.00 + shipping and received it today. Here's the picture.

I already removed this part before I bought this and it seems the thread diameter is bigger than the oem. I will try this one this weekend and let you guys know if this is good or wrong size.

If anyone had experience changing their radiator fan switch, please share your experience and let me know a good source of this part that fits perfectly in GS300 1999.

This is the one located in bottom of radiator.

Thanks.

Here's what happened today.

1. disconnected the wire cap and connected it to the radiator fan switch just to test. But the end cap of switch is not the right size or not marrying with the wire cap. So I used DREMEL to remove all reduce the size. So I finally was able to connect the ends. I ran the engine in idle and then goback under the car and heat the end of radiator fan switch using heat gun. So I saw the FAN works after so much heat is applied. Hmmm it seems it took so much heat before fan runs.

2. So proceeded with installing the new one and it went in. Thread is ok. So now I have the bran new connected to radiator and can be connected to wire end cap.

3. Then decided to test the old. Same trick using heat gun. So noticed same that it took so much heat before fan turns on.. So it looks like the OEM is still good. Since both new and old reacted only when a lot of heat is applied.

4. So decided to just use the new one. So ran the car and same happen. Engine temp gauge in car shows 185F but did not notice fan turned on.

So Question i have in mind are:

1. What temp does this switch turn on the fan? Is it 210
My temp gauge shows it is itting in 185F.

2. I checked the uppe and lower hoses and lower remains cold and upper hose is hot. So i think its good..

3. So when is this going to reach 210F temp. I already drive around but did not hear the fan at all. Does it mean my coolant temperature is always below 210? I'm here at NC and outside temp is about 60F today.
Maybe weather is enough to cool down my radiator when car is running. Should i run this in idle for longer time until fan turns on.

4. is this because of my new coolant mixture that it does not heat up to 210F.
I just drained and refilled my coolant recently with toyota long life mixed with distilled water 50/50.

5. Can this be a relay problem? Radiator switch does not sends signal to relay so i dont'k think this is a relay problem. Switch only sends on and off signal. Right?

Please help me by sharing your thoughts or help me figure out the problem if i have one
While looking for solution, can i unplug switch so fan is always on.? Will that damage the fan bec it will always be running.
