Change timing belt without changing water pump! Is it OK??
I am planning to change the timing belt on my 2000 GS4. My friend is a mechanic, he told me the water pump is located outside of engine. In order to save some money, he told me just change the timing belt first without changing the water pump. In the future, if the water pump goes bad, I can change that easily.
Is it true??
My friend has a 98 GS3 he did the same thing!!!!!!!

Yes it is okay but inorder to change the belt you basically have to take the front of the engine apart any how. So you are already right there. It makes sense to just do the pump while you are there becasue there isnt any additional labor. If the pump goes bad later then you have to pay for the same labor to pull it all apart again. If I remember correctly the pump was like 100.00 tthat amount on such an expensibve job is cheap insurance.

My friend told me you just need to take the drive belt out and then can be easily to get the water pump out, it got nothing to do with the timing belt!!!
Is it true??

Trust me, replace the water pump while you do the timing belt... im a lexus certified mechanic, ive been working for lexus for 5 years... replace the pump...
Thanks for your opinion!!
Beside the timing belt, drive belt , water pump, Do I need to change anything else at one time?.....like timing belt tensioner, seal or pulleys????

What is the expected life time of the waterpump? Or per your reccomendation the pumps is preemptively changed and we are unable to determine the life span of the water-pump.
[Assuming we have proper tension in the belt and standard drain and refil done of the coolant].
If only the above number is published or shared by Lexus/Toyota for their vehicles...
