Wanted to know if i can use any late model "A" series water pump on A15

Also, are the above timing covers and distributors interchangable?

cheers in advance

water pump, no. There are 2 types. a clutch fan type and a normal type. The pullys do not interchange and i think the mounting face to pully face is different lengths.

dizzys and t/covers yeh im pretty sure.

actually i used the a12 water pump on my a15 when i put it in you just have to use the a12 fan as well and it fits sweet as at least it did fir me anyway

yeh i know that there are at least two types. the one on my A12 has bolts back through the fan, and i have another one (off an A15) that had studs in it that nuts when onto to hold a fan on. they had different sized holes cut out from the middle of the pulley and are not interchangeable.

part# 21010-m6626
fits
a10 a12 a14 1972-1982
a12 a13 a14 11/1972-1981
a14 05/1977-1981
this info is on the side of an OEM Nissan water pump box, kinda looks like most a motors will use the same pump but I agree with the fan clutch statement.
this particular part # does not have a fan clutch. hope the info helps.

2 different types, just use the one from the 120y style a12, same anyway. pull it off your existing a12,that way you know it works and you can use the fan and pulley too.. the rocker cover is the same so you can use that too

Quote:
Early 1200 Timing covers differ from 120Y onwards (at least the ones I've seen). Timing markings for (some?) early 1200s are on the pulley whereas later models are on the cover.

Fandatstick has it right.
A10 & 1200 timing covers had a single indicator mark cast in & the different timing marks were on the pulley while later ones had a single mark on the pulley & different timing graduations on the timing case.
Both the pulleys & the timing cases will interchange, but interchange them as a mated pair in order to be able to time it properly.

Distributors are interchangeable if you keep the metal plate for the distributor with the block it came from, ..... however, different engines use different timing characteristics, so switching the distributor by itself may give you a bad timing curve for your engine.
