[concours] XK-150 Windscreen Washers and Body ID Plate

OK, OK, Lesson learned to take pictures before you disassemble…Can
anyone help me with the correct connection and routing of the vacuum and
fluid hoses for the windscreen washing system? I recently had the engine
rebuilt and find a vacuum fitting at the top rear of the intake manifold
which is now plugged. I’m assuming this is the vacuum source for the
washers. If this is correct, where is this routed? I assume to the washer
bottle. There are two fittings on the dash-mounted push valve one of which
must connect to the washers and the other must be routed to the washer
bottle…but to which of the two fittings?

A second question for the concours experts…There is a small, aluminum
body ID plate pop-riveted on the drivers side firewall just below the
windscreen. Was this mounted prior to painting and thus should be body
color or was it mounted after and thus should be polished?

Any help would be appreciated.

Hi, Pat -

In reverse order, the plate was affixed to the body prior to painting, and,
hence, should be body color.

Logical routing of the vacuum line is from the intake manifold fitting to
the dash-mounted vacuum switch, and then to the screenwasher
bottle. Operation calls for the operator to push the switch, and a vacuum
diaphragm on the top of the bottle will compress a spring, and draw some
fluid into the accumulator through a check valve (in the screenwasher
bottle head). Release the button to allow the spring to force the fluid
through the lines to the screenwasher tips in front of the windscreen. I
don’t know offhand which button fitting goes to the manifold or bottle; I
suspect that it doesn’t matter much. Fit a hose to one fitting and suck on
it; if there’s no leak, connect that side to the manifold. As both hoses
enter the engine compartment in the same area, should be easy to switch, if
you’ve chosen wrong, or change at the button under the dash. Good luck
with the new rebuild!

Pat - Windscreen Washers. Check the archives.

Body ID Plate. Partial yes to your question. Affixed to body and prior to
painting resulting in body colour. Don’t polish or I’ll send you some
squirrel tails.

Pat,
My car is still at the shop but from memory this is the setup. A small vac
hose goes from the fitting you mentioned to the valve on the dash, from
there a pipe goes to the centre fitting on the top of the bottle. Another
pipe goes from the outer fitting on the bottle back to the washer jets. The
vacuum draws the diaphragm upwards and thus draws water into the bottom
section of the chamber. When you release the valve (button on the dash) the
diaphragm returns to its neutral position and via a one way valve, the
displaced water is routed to the jets.

On the body number plate I had a look at a few other cars and they all had
the plate painted body colour. I removed mine as there was a bit of pitting
under the plate and each end had damage from some over enthusiastic disk
sander operator. I repaired the plate and pop riveted it back in place
before the final coat of paint. BTW, my plate was brass. Good luck.
