Hi all,  anyone have experience changing this pump?

i have a major coolant leak and i tracked it down to this unit however it does seem like a hard one to access and change. Once this fixed I m planning a trip to Italy in my new Alphard…not sure how this fantastic car has been kept a secret. 
Thank you

Hello welcome I would personally be not replacing the pump with a 2nd hand part 

Thank for the reply Picasso. I would buy new if i could find one… i sent enquiries to a lot of companies to find one but no luck. From some searches, easiest way is to remove the windscreen scuttle shield and wiper arms and work through the top. 

Hi there!

That is the inverter pump for a Hybrid.

Do you have the Hybrid model?

 

Your info says you have the standard petrol, so that pump obviously won't fit.

No matter how hard you try!

And this is the wrong section of the forum for a Hybrid....

 

Cheers, Nev

Well spotted Neville his profile wrong as well if he has hybrid won’t get the correct help 

Ohh… been on this planet for 37 years and forums still pose a challenge for me. I have a hybrid…it’s the auxiliary coolant pump.. managed to change it today. Had to remove the inverter to get to it but it’s done now. No more coolant leak. I will change the details on my account. Appreciate the reply. 

Hi Ionut!

Nice work there!

Apparently it's similar steps to change the rear plugs on mine,.

Initially seems like it's a hassle to take the scuttle off, but if it's like our previous one, Grand Voyager V6, the job's not going to happen if you don't!!

Cheers,

Nev

The video i found was of a guy changing his aux water pump on a prius+,he removed the scuttle panel to do it. When i looked in my engine bay and imagined what access I would have without the scuttle panel, the answer was bugger all. Little bit mortified to work around the Hybrid system with no safety training but followed common sense and came out alive. I will be honest…this car is so cool I dont mind learning how to fix it.
