Hello all!

My wife's GS350's water pump has given up the ghost. I have a replacement pump w/gasket and want to install this weekend.

Are there any pitfalls to this or is it straightforward? I have a lot of experience working on cars but hadn't had to mess with the Lexus until now.

What major components need to be removed to get to the pump? Radiator, fans, ???

Thanks for the help,

Tim

 

Here you go. Straight from TIS. Good luck. Post some pictures and create a DIY. All members would greatly appreciate it!

 

Thanks for the info! Doesn't look to bad. I'll follow up with my results and tips.

Thanks,

Tim

 

I did the job today. It took me about 2 hours. Pretty straightforward. '

I tried to take some pics but forgot to put the CF card in the camera

I marked up the repair document. It is not necessary to do some of the items in the manual.

Unfortunately, while taking off the hose from the radiator I broke the plastic connection to the radiator. I can't believe these cars have plastic radiators! That is real crap.

Trying to fix it, if not will need to throw in a new rad.

Does anyone have the process for replacing the water pump on a 07 ES 350 Lexus?

 

Tell you the truth, this is an easier job than replacing the Alternator

 

I believe all modern cars have plastic ends on their radiators you will need to go aftermarket if you want all steel

 

where did you buy a new water pump from? can you provide me with a part number?

thanks in advance

 

you can get the Aisin off Rockauto for under $100 and get thermostat too if I were you. check MyLparts.com if you want OEM

 

wow. this is a $1000 job at the stealer.

 

Dealer installed water pump, thermostat, belt tensioner pulley and belt cost approx. $870. Extended warranty took care of everything but the belt. Car had 72k miles at the time.

 

Just in case anyone is looking for a DIY here is a great video.
