I installed a new p/s pump on the Prelude and filled the reservoir. When I started the car, the fluid level in the reservoir didn't change. Do I need to prime it or am I looking at other issues?
Faulty replacement NAPA pump or more serious rack problems?
An inquiring mind wants to know.
Well, what were your symptoms?
The actual displacement of the pump itself is tiny so if the rest of the system was still full of fluid i wouldn't expect the pump itself to drop the reservoir level much just by filling its pumping bits.
Did you rotate the steering wheel, lock to lock, several times? Gotta make room in the rack too.
In reply to Trackmouse :
What he said. Pull the cap off the reservoir and have an assistant saw the wheel back and forth a few times until you stop seeing bubbles.
Strong suggestion: Jack up the front of the car when you do all of the above. When you turn the wheel, the pressure the pump sees is proportional to the friction at the tires. Until you get all the air out, taxing the pump will whip the oil into a froth making bleeding very difficult.
If you jack up the front and take as much friction out of the equation, it should be easier. I like to jack up, fire up, then do slow cycles: 1/4 turn right/left, then 1/2 turn right/left, etc until you get lock to lock. Recheck the reservoir. It will be bubbly, but at least it won't be oil mousse.
I had a chance to look at again this afternoon; no assistant though.
After slightly over-filling the reservoir, I started the car, began working the steering wheel back and forth and noticed alot of resistance.
Getting out of the car I notice spilled p/s fluid on the floor under the reservoir. Instead of pumping fluid through the system I now have fluid pumping out the top of the reservoir.
Ideas?
I watched a tech replace 2 new p/s pumps because he wasn't getting any flow after replacement. After being annoyed at the lack of flow on the 3rd pump he revved the engine and it suddenly came to life. He learned a lot that day.
If that doesn't work try working the wheel back and forth with the car shut off (and reservoir cap on). Much easier and effective with front wheels off the ground as previously mentioned.
Are you sure the lines are on correctly. Ya I know but I may know someone that made that mistake.
In reply to dean1484 :
I’d figure if he reversed lines the high pressure side would’ve blown off the hose. But I guess it could happen.
Ill second the comment of “start the engine and rev it a few times” since it’s a pump, it has to be doing work to pump fluid into areas where there isn’t.
In reply to Trackmouse :
There is no way for the lines to be reversed. There is one hose from the reservoir and it slips onto a tube integral to the pump. The high pressure side has a totally different fitting design where the hose is attached to a fitting with two screws that have to be turned just to get the tip into the pump.
The engine was revved more than a few times into the 2-3k rpm range. Perhaps that just wasn't enough or for long enough.
I'll try again in the next couple of days.
