OEM vs. Aftermarket, when it's OK

Marlin sells rotors for trucks but I've had good luck with Napa rotors
 
I've also had good luck with a NAPA rotors. Autozone ... not so much.
 
Same with o reilly's for me. Had them on my old 89 and they rusted quickly and I live in Washington
 
The problem with NAPA is they have 4 choices, from $20 to $140. What to choose?
 
Middle one is what I go with. The high performance ones aren't worth the money and the cheap ones aren't either.
 
Lol look at the one review of 'em
 
I have been diligently buying OEM stuff whenever it is available. I do wonder sometimes if I am just paying for the brand though, c'est la vie.

Does anyone know if the OEM thermostat for a 60 is different from Toyota vs. Aisin? I know its not a huge price difference but curious if its the same item in a different box?
 
I cant answer that, but the Altrom line from Napa is typically OEM just rebaged.
 
I had a heck of a time getting the oil pressure gauge to work when I swapped in a SR5 cluster. The bottom line is that the pressure senders from AutoZone, an Intermotor aftermarket and an "OEM" pressure sender made by Senkei bought from LCE all behaved differently in the FSM test where you use a 3.4W bulb that you connect to the (+) terminal of the battery and ground it to the pressure sender. The bulb should get brighter with increasing throttle. These three blinked and the blinking frequency increased with throttle. None of the above gave me a working pressure gauge. I thought I had a bum pressure gauge, but it Ohm'ed out according to the FSM and responded to a 9V battery. The blinking during the test concerned me so I finally bought an OEM pressure sender from beno that is made by Yakazi. It behaves like the FSM says it should. I now have a functional oil pressure gauge.

I spent way too much money to get the OEM pressure gauge to work as none of these pressure senders are returnable. Luckily, I only bought the Intermotor, Senkei and Yakazi pressure senders, the PO had installed the AutoZone pressure sender. :lol:

My suggestion, always go OEM for as many electrical parts or sensors that you can.
 
Since the discussion has reared its head again ...

Recently, after 30+ years, my AC crapped out. Many of those years were in the Palm Springs area where it received a whole lot of use. So, naïve me was just going to swap out the compressor and call it a day. But, a buddy that works for Toyota as a trouble-shooting engineer told me the entire system needed to be washed/cleaned out to do the work properly (cuz of the oil). After looking at the cleaners, and the process, I decided to just swap out the parts with new. Plus, I was sure my evaporator was clogged up, and the condenser had seen better days sitting out in front of the radiator.

Lucky for us all the stuff is still available from Denso aftermarket. So for about $400 I bought a new evaporator, condenser, drier, expansion valve, and a reman compressor. All Denso. The only parts I'm going aftermarket are the hoses. The discharge hose was available aftermarket for cheap (ya, will probably regret it). The suction hose was not, so I'm having it remade by a local shop.

Since this was a recent purchase I can't tell you any results since only 2/3 of the parts have been removed, and nothing has been installed. Here is a pic of the bits to get you all aroused. It's all Denso goodness. I figure it's November, and I won't need it until May ... so I have plenty of time to finish.

AC bits.webp


Now, if you will excuse me, I need to get to it and pull the evaporator ... the last bit in the equation.
 
:clap: Wow that is nice stuff.

Are you gonna be able to re-charge with R12, or are you converting to R134a?

Going to R134a for cost and ease. I already had the fittings, and all the new O-rings are 134a OK.

Im on the same boat with the 1st Gen, I have just been putting off the conversion due to sheer laziness though. Beno should be getting me all the R134 conversion bits in my next parts order, but I will definitely be picking up all the Denso vaporator, condenser, drier, expansion valve, and compressor, I am picking up a new fuel pump from Denso anyways. Might as well start anew;)

One little comment about the condenser. You will notice there is a second row about 4" tall connected by that silver tube. This is a 4Runner specific condenser. The truck doesn't have this second layer, but the larger condenser does work. You might need to source the connection tube to the drier.

Mine’s a 1st Gen Runner, not mini, should have specified.
 
That almost makes me want to fix the AC in GB..... Almost...... I can't believe how cheap that all was though! :D
I was very pleased with the cost. One little add. I had to visit the dealer today for a couple of other things. The suction hose was available from Toyota ... for $126. OUCH! But, I ain't doing this again. Also ordered the pressure switch and the thermistor even though I was told they hardly fail. I don't ever want to do this work again so I'm taking care of those while I'm in there. I'll know tomorrow if those are still available (computer down today).
 
very nice - i feel the same: want to change everything out now for some nice new shininess! thanks for posting
