Long story short when i got the waterpump for the 3rd gen i got the one for the second gen, now reading through the stickies it says that a gen 2 pump will not work on a gen 3? now the pumps look exactly alike with the exception of the propeller on it, so the real question is will it work? and has anyone actually tried it? i know they are different but they should work pretty much the same right? Pic below, brown prop on 3rd gen pulled from motor, stainless is from 2nd gen pump

yes it works.
Just seperate the pump from the housing and swap housings.

Looks pretty much the same to me, should work. Its the outer area of the pump what is different , the part that the hose goes to, it bolts on to the pump

if i were you i would get rid of that pump and go buy a OEM gen3. the one on the left looks like an oem replacement style from a parts store. the fin design is supposed to be know for developing cavitation and hot spots, due to the design. the plastic OEM toyota is supposed to be a much MUCH better design.

toyota OEM replacement pumps have metal fins

hold up... what is different on the outside? take pics of the outer side by side so we can compare...

Hi,

such a stainless rotor is also used on gen.3 engines, the issue is the plastic one pumps way more in front of the better rotor design and less housing/rotor clearance.

the correct part number is
16110-79125

hope it helps

On the front they are identical, bolts up where the old came off just fine, everything lines up no issues there, just want to make sure the pump will work on the gen 3

simple answer is ...yes. explaination is below.

ok, so all you need is to replace the pump itself and keep the 3rd gen rear housing attached to the block and you will be good to go. the front half of the 2nd gen pump will work but you have to keep the rear 3rg gen housing is the concern.
so if you are keeping the rear housing on the 3rd gen you are A OK with just swapping that pump you have!

if you want the whole shabang!
16100-79226 is the 3sge beams complete front and rear assembly only one left in stock.
or the direct swap...
-79236 is the st205 3sgte match number but they are out of stock at the moment for a week or so.
On the lithiatoyota.com website and just use the part number to order and NOT use your car info or it will mess up the order and try to order you the wrong stuff!!

Wait, a bit confused here, what do you mean by swaping housings? as of now i have the one on the left bolted on in place of the one on the right

The water pump HOUSING is diffrent. The pump itself is the same.

The water pump HOUSING is diffrent. The pump itself is the same.

To make it simple to understand.... The pump is what u have pics posted of. The housing is the part that the pump gets bolted/connected with. The housing is bolted to the block and bolted to the two stainless pipes coming out of the other side. The pump blades fit into the hole of the housing when u install the pump. Hopefully that clears things up.
