58 W.W. Squirters.

[Brad H.]

A couple of months back I had Tom Maxwell send out the complete washer system, pump and lid with the water container, vac. can and all the correct hoses, hooked it up and worked instantly, one month later as soon as I turned on motor the wipers would come on and not shut off, sent it back in and and he had to purge the system , had dirt in it,( we won't blame anyone) got it back and it worked fine, a couple weeks later tried it again and it would not even squirt, worked it for a while and got it squirting again but would not cycle correctly, only one squirt no matter how the screw was turned, he said send it back in again (west coast to east coast, madning) Has anyone had this problem or anyone who knows these units have a clue before I send it back again, Everything under the hood is new, motor, carb etc. I have even taken the hoses off and checked for holes and they are all fine, could it be something with the button on the switch. Top Flight last week. Thanks , Brad.

Re: 58 W.W. Squirters.

Brad, I am planning on sending Tom my pump and coordinator soon. I started a thread about a month ago and asked for feedback from owners that had sent in their system to Tom. Most replied that their system was still working after several years, but all agreed that once it is working, it needs to be cycled at least once per month. I am interested in reading what others have to say.

Is your vacuum can holding a vacuum? Sufficient vacuum coming from engine?

Re: 58 W.W. Squirters.

Joe, I purchased the whole system from Tom and installed it and it ran fine, nothing was changed under the hood to change any Vacuum to my knowledge, now nothing, how exactly do you check the vacuum at carb or Vac. Tank, others feel free to chime in. Thanks, Brad.

Re: 58 W.W. Squirters.

To check the vacuum, I went to O'Reilly Auto Parts and purchased an inexpensive vacuum gauge. Pull a vacuum hose of the carb stud, insert the gauge nipple onto the hose, start engine and see what the gauge reads. I believe Tom Maxwell told me I should see around 15 psi. He said that if there is 15 psi of vacuum on one side of the vacuum cannister valve, there should be 15 psi on the other side of the valve. I determined that my coordinator module was bad because I put the tube in my mouth and created my own vacuum and the coordinator did not push the wiper motor on; bad diaphragm and Tom fixes that as well.

Re: 58 W.W. Squirters.

Joe, I'm a little confused now talking about the coordinator,Tom say's this doesn't control the squirt, he rebuilt mine several month's back, are you saying if you blow into the lower end of the coordinator hose it should move the wiper's?, as before, all my stuff is rebuilt. also are the wiper's supposed to come on when you push the button on the switch? Again, Thanks, Brad.

Joe and Brad -

Just to clarify what makes the system work, vacuum is negative pressure (think "suck"), and is measured in inches of mercury, as noted on the vacuum gauge face, not "pressure".

Re: 58 W.W. Squirters.

When you push the button on the dash, it opens up the flow of vacuum to the pump controller (mounted on top of the water reservoir); vacuum is applied to the coordinator (connected to the wiper motor) and this turns on the wipers and starts pumping water to the windshield. If you want to see if the coordinator is still working, pull off the hose going to the coordinator and suck on it. It does not take much suction if it is working to push the switch away from the coordinator and activating the wipers. When the pump controller shuts off the vacuum, the water stops squirting, the wipers swipe another time or two and they stop and park at the bottom of the windshield.

Re: 58 W.W. Squirters.

So John, after reading my post what might you suggest I try first, second, third etc. before sending my pump and lid back 3000 miles to find out I did not need to do this, as before this is an all new system, also co-ordinator was redone by Tom and Wiper motor has been rebuilt back i n 2000 and not used much but is fine. Thanks, Brad.

Re: 58 W.W. Squirters.

The only thing Tom can not check is the vacuum when your system is hooked up. I realize you system is new, but you are going to have to check each component while it is on the car.
(1) determine how much vacuum you are getting off of the carb stud
(2) make sure you are getting good vacuum p.s.i. out of the vacuum can
(3) make sure the dash switch is working properly; pull the vacuum hose off the nipple on back of switch, install a short piece of hose, suck on it WITHOUT pushing the button, if you can't pull air through it, the switch is cutting off the vacuum supply and that is correct. If you suck on the back of the switch WITHOUT pushing the button and you CAN draw air through the hose, switch not working properly.
(4) Confirm that the coordinator will turn on the wipers as I referenced in an earlier post. Pull off the hose from coordinator, hook up vacuum gauge, start engine, get someone to push the button on the dash switch, and see how much vacuum you get to the coordinator hose. There has to be enough vacuum to coordinator to push wiper switch to ON position.

If your vacuum readings are similiar; carb stud, vacuum can valve, coordinator hose, it may be the pump mechanism; MAY be the pump mechanism.

Thanks Joe, this gives me a better idea of how this thing works, I will try these and go from there. Brad.
