hi, what do i do with the rubber o-ring included the the water pump gasket kit?
in one gasket kit, it's a flat ring, the other gasket kit it is an o-ring.
the ring is the size of a nickel.
thanks.

like a miata's small inlet tube, which my engine does not appear to have.

What?  It's used for the heater pipe that runs under the exhaust manifold, you better replace that o-ring unless you want to smell burning coolant.

i need help finding this.
i have an FSM, but cannot find any reference to what you're speaking about..

It's called the coolant bypass line. It runs under the manifold and plugs into the lower rad hose water neck with that o-ring.

[Rocketman]

This is the bypass pipe, it runs along the front of the block.

hoo, boy.
this connection is leaking, as expected for that lack of maintenance when i couldn't find it for that o-ring.

i just found the connection, totally blind, removed manifold shield.

i unbolted the inlet-pipe from the waterpump inlet.
i removed the lower radiator hose.
-- but i cannot get the coolant bypass line to pop-out of the inlet-pipe.

-- there is no clamp for this line, does it just "pop out" of that inlet-pipe??

it's a tight space, but i feel i'm working it overly firmly..

This pipe runs under the exhaust manifold over to the heater core.  You need to unbolt a corner nut from the exhaust manifold in order to remove it.  Then remove the hoses connected to it and pull it out with a bit of effort it should come out.

that water pump inlet pipe and the two bolts that hold it in place are just in a terrible spot.
i eventually got it.

- 1. with a tube cutter, i cut the bypass pipe between its engine block hanger and the elbow.

- 2. i was then able to pull-out the left half of the bypass pipe and the stubborn water pump inlet pipe to separate them, paint them, re-gasket, put them back into place.

- 3. i reconnected the splice in the bypass pipe with 5/8" hose and hose clamps.

i may post a pic here someday.

i'm not ashamed of of cutting that bypass pipe.

i'm in this car often enough that if i can invent methods to prevent removing excess fasteners/parts for ease of future access, then i will.

Just watch the heat from the exhaust manifold on your rubber coupling there. Glad you got it all sorted though

Wait till you get my problem, because of the way I mounted the clamp on the radiator hose, I have to run a longer then average power steering/ac belt.  Really made me feel like an idiot when I realized that was the problem, but I'm not taking it all apart to fix something so minor, and so annoying.
