Aux Coolant Pump Dead - 87 300D Turbo

[a2t]

Im getting ready to install Frybrid kit on my 87 300D.

Ive noticed slow heat last winter, and heard the aux coolant pump could be dead. So, I tested mine tonight and sure enough dead as a door nail.

Now I dont know if this will be a problem or not, but it sure would be nice during the veggie kit install if I had some way of puhsing coolant around without the motor. I was hoping to jump the aux pump and let it push the air out. Guess thats not going to happen.

Is there some way to rebuild it? I pulled the washer fluid res and the pump is totally caked with 250k miles of who knows what. Doesnt look hopeful.

I was also considering retrofitting a small electric pump and just hot wiring it to go whenever key on. Although I do not want to risk frying the ACC, and dont really understand how that thing ties into the pump (ie, can I just snip the plug running to aux pump and run new wires?).

Any and all help is greatly appreciated! Oh by the way the monovalve seems fine, being that I get heat when I should (albeit slowly at first) and cool wen I should.

Theres only 1 monovalve right? For some wierd reason the manuals all say there are 2 monovalves. Pretty sure Ive tracked most every inch of hose, dont see more than 1 mono.

Thanks waaay ahead of time.
