Windshield washer pump
Do you have to remove wiper motor to replace washer pump on a 72 Chevy

Re: Windshield washer pump
It can be done, but it's biotch to do it that way.. The pump bolts to the motor, it's just difficult to access those little bolts.. Removing the seat gives you room to lay out on the floor while reaching up under the dash..
Here's an alternative method I used if you're interested.. Install a "universal reservoir" with the pump attached to it.. Disconnect the wires at the OG pump and route the wires from the new pump to that plug.. The new pump will be activated from the original wiper switch. The plus to doing it this way is all the water lines are now outside the cab, no more wet carpet from a leaky hose or pump.. [EDIT] If you go this route, it's not necessary to remove the old pump.. |
Re: Windshield washer pump
I agree, getting the wiper motor out to get to the pump it a biotch! I did it and while I had it out ended up only replacing the weather seals for the motor. I believe even once you get the original "fixed" it will just end up going bad/leak again.
So I put a external pump on my reservoir. It isn't very hard to do, IMO. |

Re: Windshield washer pump
Thanks for replies looks like it’s unanimous, mount pump in engine bay. Looks like Frank’s PICKMUPS sells a kit

The full size trucks of the same era used a similar but larger reservoir. The s10 reservoirs are available new, AFAIK the full size reservoirs are NOT. |

Re: Windshield washer pump
I installed an aftermarket pump on my wiper motor trying to keep it stock-ish, but since that pump has died I'll be going the route of 67C10Step and installing an '88-93 S10 reservoir with pump in the engine bay. This will simplify the hoses and keep any potential leaks outside of the cab. RockAuto has the pump electrical connector for <$4, and the complete tank with pump for $22.

I just wired in a universal inline pump to my stock reservoir. I've done it to three different trucks over the years.

Same mod here, works great and you don't have to access the pump/motor up under the dash in the future if there is a problem. PITA to get up in there, especially with AC.

Re: Windshield washer pump
Good info! The aftermarket pump shown by 3757Chevy is like the one I had mounted to my wiper motor when I rebuilt my '67. I checked for 12V at the washer pump connector which is good, so I removed the pump and sure enough it's dead. I pulled the hoses out of the cab and found some rubber plugs to put into the firewall grommet for now. I save plastic caps and rubber bumpers just for projects like this. I'm still sold on the S10 tank, pump and connector as the original jug is loose in its bracket and needs a couple of cable ties to keep it snug.
As others have done, the plan is to wire in two 18ga. male blade connectors, use the OEM washer pump electrical connector and fish the wiring with the hose through the left fender. I might also add a check valve to keep the washer fluid from draining out of the lines. For less than $40, it will be a fun, easy project, clean up the engine bay a bit and provide easier access if/when the pump dies. |
Re: Windshield washer pump
When you guys use one of these universal electric pumps, what do you do about splitting the output hose into 2 hoses for each side of windshield? Is adding a tee from something like drip sprinkler OK? Are there any clever ideas for getting the wire through the firewall?

Re: Windshield washer pump
I just used a T near the firewall before they go into the cowl to the spouts. If I recall correctly I used a T from my vacuum kit.
As for the power, I just ran it through the nearest hole from the original location under the dash. |

As for the wiring, when you move all the washer hose lines under the hood you now have three holes in a grommet going through the firewall that were once used for those. I ran the wiring through the fender with the hose, then into the wiring gutter on the firewall, and through one of those holes. Plus, it put the wiring coming through pretty close to where it needed to plug in anyway. I can get some photos if it would help. |
