Evidence of waterpump recall/replacement is300h

Colinb623 · November 26, 2022

Hi all .I'm just wondering when was the recall on the is300h for the water pump ?

Also is there a way of telling was it replaced?

My 2016 fsport has 90k miles on the clock and has full lexus service history

There was no recall for water pumps on the IS300h in the UK. Some leaked prematurely and were replaced under warranty.

If your one has got to 90k miles then there certainly isn't a manufacturing issue and wouldn't be a surprise if it started to leak at some point as they don't last forever.

The Gov MOT Website also shows if a vehicle has outstanding recalls.

Do they just go bang, and suddenly you've got a cooked engine?

Or do they just slowly leak at first, indicating it's time for a change?

Its a very easy DIY Job, I recently replaced the Stretch belt that drives the water pump at 50k as a preventative measure old one at 5 years old looked fine, I reckon 90k is the recommended mileage. I was pleased to see how accessible it is. The engine is mounted side ways being rear wheel drive.

is literally a 1 hour job. Drain & refill the coolant car has to be in maintenance mode to bleed air out of the system & your ready to go. Hardest bit is getting the belt back on!

They dont just go bang unless the water pump propellers seize up but rest assured it is unheard of on Lexus/Toyotas.

Common to leak coolant past the seal evidence of pink or red coolant around the housing. Its a very small drip not anything to be worried about most drivers would not notice this as it is a slow process once it starts leaking you will have plenty of time to react either top it up & continue or get it replaced. For the engine to get unreversible/terminal damage one would be seriously arrogant because the temp reading will be climbing higher than usual or potentialiy steaming warning you to get it addressed if ignored expect blown head gasket worst case scenario or if your really unlucky you would turn into a bbq. (Just kidding) its nothing really to worry about.
