Hi, I'm Noel (knowll) Ibought a 84 GS as a fun back-up car for when i sold my 92 300zx. The ZX is totalled so the RX is now my daily driver. I've owned 2 300zx's in the past 4 years and only begun to learn how to work on cars with them, so the RX is a whole new experience. I'm learning fairly quick with the help of the Hanes huide and reading everything and anything on the rotart engine. I LOVE the car, I love hearing the winding sound speeding up and slowing down it's like none other.

At the moment my project that I'm working on its my coolant/oil system. I have removed and am repalcing the following :

REMOVED:
-radiator
-water pump

REMOVING:
-Thermostat
-Beehive oil cooler to replace o-rings (pretty sure they're casueing my oil leak)
****does anyone know where the other 2 o-rings go??? I found a thread but
the pictures are "X'd" and wont show up.

-thanks Noel

 

what do u mean about Other 2 o rings?

the beehive is bolted to the block with to studs in the beehive with 2 corresponding nuts underneath, and between the block and the hive there are 2 o rings that with age do have a high tendancey to leak, dose this clarify anything?

As far as everything else you mentioned, it is all pretty straight forward, a note tho, if you do end up removing the housing that the water pump bolts into, between it and the block on 2 of the studs coming out of the block there are 2 vary thin washer that need to go back on if removed, this is something that can be over looked potently causing leeks.

 

if u have a haynes manual there are 3 bolts which it says to "never losen" the other two o-rings are hinding there, i've found a few pictures of them now and even though it says to never loosen from a lot of the threads i've read people do replace all four, if not the top two can cause leaking. thanks for the advide on the washers, much appriacted!

 

re: water pump:
be r-e-a-l-l-y careful re-torquing the pump back on!!! only about 16 Ft/lbs of torque or you'll strip 'em!!!
Great time to replace ALL the heater and rad hoses if they haven't been done!!
I use a dab of good old axle grease on BOTH surfaces of pump AND connecting points of hoses - seals water-tight and makes removal a BREEZE next time you service these parts (like: no scrapping off old gaskets, for eg.)
