    Just saw the pictures of a Renegade II that where posted. Notice the location of the heater hoses. Seen other pictures of the routing being different. One picture is of a Jeep with a Dated, Oct of 1969 ( the silver Jeep). The two hose route to the back of the engine and next to the fire wall. The other picture of the Renegade II, show one hose by the firewall and one hose going in front of the carburetor. The silver Jeep was put back original, as far as I know. Any input

    I have seen other Jeeps with the routing in front of the Carburetor and my Jeep had them both at the firewall.

    Mine has both back along the fire wall now, but I took off the air pump and all the emission control items right after I got it, and so maybe when I did that I rerouted the hose to the back to get it out of the way, but that was 47 years ago so I do not remember for sure. :shrug:
    It might be a case that originally they had them both back along the fire wall, but when they added all that emission control stuff they had to reroute the one heater hose to the front. But I also notice in the yellow Jeep a flush out tee back by the heater has been added, so maybe somebody along the line did some hose changing. I also notice that the coil is in a different location then mine is, which was right behind the air pump where the front heater hose is routed in the yellow jeep, and my coil is still in the original position so I think the coil would have been in the way to route the hose that way it is in the yellow jeep.
    So in answer to your question, who knows for sure.;)

    WYOMIKE, can you get me a picture of where your coil is. Need to install mine and was going by the Renegade II picture

    The bracket I just sent you is the same as the yellow one that has it bolted to the alternator bracket.

    Here is where my coil was mounted from the factory. I must say however over the years I have seen coils mounted a lot of different places from the factory. So all I can say that for the time frame mine was made, May 71, this is where they mounted them.

    With that location of the coil, I can see why both hoses where routed around to the firewall

    Did anyone notice the non-used original hose loop (@ rt front of intake & painted blue) and the added loop on my jeep, and also the silver jeep and the added loop on my jeep?
    I do believe it had to do with ca smog for the different routing.
    fwiw re the prestone "T". I dislike to see those and feel it was the cause for the p.o. to invest in a re-core of rad, heater core, thermostat housing, water pump and my recent freeze plug replacement. If you do, don't use the caustic cleaner for any longer than a few minutes. I've seen some people use vinegar. Whatever is used flush the heck out of it and add the correct anti freeze mix. Since I now have it running and allowed it to heat cycle a few times I plan to again check the pH and may have to drain again.
    Too many people use it and end up leaving it in entirely too long.

    The hose routing and coil location on my '69 match the second picture. It was smog equipped as well.

    1967 CJ5A, what does your rad cowl sticker read? I'm curious about how the roll-in of federal smog requirements resulted in added components. I'm also qurious how many jeeps retain the air-pump and related components.
    I posted my pics as it is rare to see a jeep, much less any vehicle, basically unmolested. Restored vehicles often include liberties taken by restorers, shops that have wrenched on them, and owners over time. Our jeep has had hands laid on it as well, although I think it's been minimal, save for r&r of cooling components, addition of rad overflow, tune ups, filters, past conversion of oil pressure gauge to mechanical, my recent replacement of oil leaking coil and spark plug leads (retained original).

    Oddly enough, there is no sticker, nor evidence of one. I'm not sure what to make of it. The Jeep has original paint too. Before I got it, there was little evidence of any work done under the hood, other than a carb rebuild, ignition tune up, and radiator repair. Alternator, water pump, smog system, etc. were untouched.

    Didn't mean to hijack this thread, yet smog equipment appears to have triggered changes to underhood configuration.
    The federal clean air act did not become effective until 1968 model year as the req's were made law in '67. Regan signed a law in CA in 67 that also affected '68 model year vehicles.
    Motor Vehicle Air Pollution Control Act of 1965 directed establishment of auto emission standards.
    idk if 67 required any "controls" and know that 68 vehicles (some anyway) had a vacuum valve that controlled spark advance until warmed up and iirc this is when heat risers first appeared. Does your jeep have a exhaust heat riser and damper in air cleaner snorkle?

    The heat riser is present, and as I understand it, its function is to block off the exhaust on that side, forcing hot exhaust through the passages in the intake to the carb. There is no snorkel or shroud on the exhaust manifold to create the hot intake air. The oil bath air cleaner, unlike the paper element filter, has no provision for a snorkel.
