Power steering fluid is low, and is a golden yellow/tan sort of color — not ATF red or Pentosin green.

Should my power steering have the Pentosin CHF202 fluid? And if so, do I need to flush the existing fluid before adding it?

Fuel filter is also due to ...

I finally installed the new voltage regulator last night, and it did indeed fix the power pulsing (and a few random O2 sensor type codes that I suspected were because of the low power). Brushes were super worn down on the old one (see photo).

Ran the car for a while to charge the battery up, and ...

I don’t have a 10A charger...

What about hooked to another car’s (known good) battery with jumper cables — if I turn on the car then, and it’s still doing the pulsing, that would imply it’s the voltage regulator right?

Will do—thanks again IslandV70.

As an update, if anyone is interested: I got a digital voltage reader like Oragex suggested:

The battery voltage with the car off is indeed reading low: around 10.4V

When I turn the car on and it is "pulsing," it is pulsing between around 10.8V and 13.8 or 14V ...

IslandV70, I checked the connections at the battery in the trunk — where else should they be checked?

I think my multimeter is not giving accurate readings. I’m ordering a Bosch regulator and will check the battery after it’s installed.

Thanks for the reply, oragex!

I’m at around 122k miles.

Follow-up questions:

Right now the battery appears to be holding its charge just fine — does that affect your guess at all?

And just so I can better understand — what is it that makes you think it’s just the regulator, as opposed to the ...

Hey all

Here is my situation — would love to hear your thoughts:

Battery light came on while doing a high-rev acceleration up an uphill freeway on-ramp
The next time I drove the car, the idle, headlights, and all instrument lights were pulsing/dimming, all together, about once or twice per ...

Thank you!!

Hello friends,

I have cracked front brake hoses & brown brake fluid.

I have found good tutorials for each of these jobs, but for same reason I can't get my head around the best/smartest way to sequence the two jobs, with the goal obviously of avoiding air bubbles in the hydraulic system.

Replace ...
