I believe the factory spec for R12 is 24oz. I have heard that the spec for 134A is in the 20oz range, although a Denso tech stated that the actual Toyota recommendation was 93% of the R12 charge when retrofitting. That would be about 22 oz. Any voices of experience as to the right charge? My...

Thanks for the info. No, I do not planto bypass it long term, I may need to bypass to test it. Thanks again.

I am going through the troubleshooting process on my AC and have been gleaning info from previous threads. Two basic questions: 1. Where is the low pressure switch / sensor located? and can it be bypassed safely if I know I have a good charge in thge system. I'd like to be able to determine...

Thanks, very helpful to my understanding.

Doug, Thanks for the advice. That's kind of what I was thinking. I'll check the power at the compressor in the morning and see if the circuit is good to that point. If not, I'll check at the output of the dash switch and see if it is functioning. I was trying to determine if the dash switch fed...

My blower is working correctly, by blue AC switch lights when depressed, but compressor clutch is not engaging, nor is the idle advancing. The 10amp AC fuse is good so that's not the problem. I also do not believe it is the 30amp breaker as that also knocks out the fan and AC switch, and it...

Are there any direct drive cooling fans available to install on the FJ60? I recently had to replace the fan clutch on mine, and I think the replacement clutch is delivering questionable service probably due to less than high quality manufacture / engineering. I was thinking of just installing an...

My brother and I have been doing work on some of our FJ60s and ended up with one additional factory headgasket than we needed. This one is Toyota part no 11115-61010 and is specified for all F2 engines from 1975 thru 8/84. I also have one of these installed on 1982 block with a 1985 head and it...

I would like to further clarify on the 61010 application, as I don't want my prior post to be misconstrued. First, let me say that i agree with Jim's comments completely. I am not in any way recommending that the 61010 gasket is the proper application for the 1985 -87 later variant 61040...

For future reference, the 61010 OEM headgasket does function perfectly well with the 85-87 cylinder head for which the 61030 headgasket is spec. I just installed an 85 version (F2/F3)rebuilt head on my 1982 FJ60 block and it runs cool with the 61010 underneath. Spot checking the head temps with...

So it appaers from jim's response I should be good to go with the 61010, as the differences are negligible. I think from what i can see on line that maybe one water jacket opening in the HG is different but all else appears the same. Could not be signifcantly different as the HG casting of the...

The dealer said the correct gasket was a 11115-61010 for all the 61040 head castings. that is the one that i bought and installed today. Is that really a problem?

So, I'm assuming from the information posted that, although the manifold face is different than my earlier 61040 head, this 2F/3F variety is safe to use on my block and the standard 2F manifold gasket is okay as well, correct?

Based on the information in the below thread, it appears that this 61040 head with the extra holes was used on 85 and later F2 engines, as well as the foreign market 3F carbed engines. I believe Toyota the same head on both applications although the manifold requiring the additional fasteners...

Here are the two heads - manifold side up - sitting side-by-side.
