1970 Washers (WS and HL)

[Tony H.]

My washers on my 1970 Corvette do not work. I have fluid in the bottle but no water action at the WS or HL which leads me to believe that I'm not getting the appropriate pumping action at the pump. I want to preserve the 1970 set-up which has five nozzles. I think the problem may be simply poor seals that are preventing adequate suction of the pump. Does anyone sell a repair kit for 1970 washers? Are there any recommendations as to how I can rejuvenate the o-rings/seals on my system? Thanks for any help you can offer.

Tony

PS. I was successful in finding, restoring, and installing a horn relay from the salvage yards for my '70. Thanks for all the help and encouragement!

Re: 1970 Washers (WS and HL) -- Clearing nozzles?

How do I test the HL nozzles for spray proper pattern? How should I clear plugged nozzles if I determine that this is causing the HL washer to not operate? Should I soak the nozzles in vinigar or is there a way to clean them up?

Thanks,

Tony

Re: 1970 Washers (WS and HL) -- Clearing nozzles?

Before you try to rebuild the pump outlet, have you tried priming the pump by forcing fluid up to the inlet? In extreme cases, I have forced fluid under moderate pressure through the entire system, then allowed the pump to cycle and it maintained the prime and operated normally unless the system was not used for a long time (months) give this a try before you give up.

You can purchase a pump repair kit in the "HELP!" brand section of most auto parts stores. The kits will be three port type, but you can use most of the internal parts to rebuild your pump. You won't be able to replace the outer part with the port tubes on it, though. MAKE SURE THAT YOU DON'T DAMAGE THE 5 PORT OUTER SECTION OF YOURS.

Re: 1970 Washers (WS and HL) -Thanks

Thanks Bill and Joe,

I will try priming the pump tomorrow when the JBWeld dries on the WSW lines.b I will also add the rebuild kit to my list next time I go to the parts store. I'll keep you posted on what works.

Priming

This has worked for me EVERYTIME.

(1) Remove pump to squirter lines, fill with water and blow to make

sure they're clear and functional. Might have to play with a

pin at plugged squirter nozzels.

(2) Remove pump inlet/outlet nozzle assy and gasket assy. Soak

HEAVILY overnight in WD-40 to rejuvenate these rubber pieces

(don't forget the umbrella valves) working the WD-40 gently

into the rubber by hand now and then.

(3) On re-assembly, FIRST fill the pump shooter cylinder with washer

fluid to partially prime it before re-attaching the pump's inlet

and outlet valve assy.

(4) Blow water into the hose line to the res to prime it and set it

aside.

(5) Take another hose, insert it into a small bucket, hold it above

the washer for gravity feed. Siphon water and connect to pump

inlet.

(6) Actuate the washer system and within a few squirt attempts it

should flow naturally. While it's squirting exchange your prime

hose for the system's supply hose and check that it picks up and

rids itself of any trapped air.

Last, use the washers periodically to keep the internals lubed/primed.

There is an article in the restorer that gives a step by step rebuild of a 5 port pump. You will need 2 rebuild kits to do the job.
