    So I've been reading quite a lot of posts and can't see where this has been answered. So hopefully someone can chime in or link me to a post where this is discussed. I have a '92 cougar 5.0 HO engine with the reverse rotation water pump, like in the attached picture. I want to retain the entire front serpentine belt system in order to use the more modern AC compressor and other accessories that came off the donor vehicle when this goes into my Mav.

    I know I have to swap to a front sump oil pan, but was hoping I could get some advice on where to drill out the timing cover from the '92 engine for the dipstick tube, and clear all the belts and pulleys. It does not have the boss like the older timing covers. The current one is sacrificial if I have to replace it anyway, so any ideas might be worth giving a try.

    Has anyone figured this out or does someone know of an aftermarket timing cover that has been modified for this application?

    I do have a standard rotation cover I bought used (pre-EFI, has the front dipstick tube hole), but it is definitely from an older generation of engine. Can this go on, find a reverse rotation pump and use my existing serpentine belt pulleys?

    Thanks in advance.

    I have one of each but can't tell if my reverse rotation cover has the boss, I need to pull the accessories to see.

    That's the "late " reverse water pump cover used with electric fans... It's very different from covers that used mechanical fans...

    AFAIK the original pulleys only work with it as it shorter overall than earlier covers... There are some differences in the earlier covers, the EFI on my T-Bird 5.0 is approx 3/8" shallower than the one on my Comet...

    Back when I was installing the 306 in my Comet, I was talking with the local "mustang" guys and was told there was never a reverse rotation cover used for the cars(at least prior to the covers used with electric fan)... Mid '80s & early '90s used same cover whether reverse or std rotation... I basically verified that info as three engines I had with EFI & reverse rotation pumps all had the 302D cover... The last one(351RF) was used on trucks and is only one that inlets are redesigned to enhance flow when spinning pump backwards...

    I drilled my timing cover in the blank boss on the right side at the bottom. It's been that way for probably 15 years. I use a serpentine belt setup with reverse rotation pump.

    20150208_190718.jpg That's sort-of the cover I'm using ill get closer a pic of it tonight, I drilled a hole and used plastic air line for the tube silicone on the bottom side of the timing cover. I'm not using the factory brackets either though. But one could easily make it work I would think

    Thanks everyone. The interesting thing about my cover is the round area where the impeller fits into the cover, not bolted on as the style shown in Krazy's table of pics, which was very interesting. Mine is just like the one in my original post, but it does have a belt driven fan, not an electric fan.

    I looked up the ford part number for the cover and it's: F1SZ-6019-A and I verified that the pump is supposed to be a reverse rotation for this car. Interesting thing I also found is that there are both electric and belt driven fans shown in the parts catalogs for this year of car, so maybe that was just a transition year and I got lucky enough to have the belt driven one.

    Nick, looks like your set up is the closest to what I may have to do. I look forward to seeing a closeup of how you did that.

    All serpentine water pumps are reverse rotation whether electric or clutch fan, with one exception, early 81-89 Crown Vic/Marquise/Lincoln. it uses a standard rotation, I kept the explorer cover because it has the boss for the crank sensor & I want to go back to EFI eventually

    You won't need the crank sensor unless you go back to the Explorer distributorless ignition. If you go with the conventional HO SFI or aftermarket you won't need it.

    Some version of this yes except maybe with LS coils instead of the two 4 towers coils

    Put the parts back on the front of the engine and found a way to snake the tube behind the tensioner pulley. Should work fine. Will have to shorten the dip stick once I get the engine rebuilt and back together and find out where the oil level hits on it. Had to tweak the bends a little, but not bad.

    It all came with the donor, so hadn't really thought through that yet. If it will fit in, will start there, then maybe look for that down the road. The Mustang set up does seem more compact and looks great in your car. Definitely will use the intake from the cougar as it points more to the front and should miss the tower. I had bought an explorer, but didn't like how that intake pointed straight off the side. Was your set up an after market bracket system, or did you take it from a donor?

    I'm doing the same thing, my serpentine setup is from a Bronco. It actually fits well in the car so I plan on staying with it, no point in spending money there when it can go into other parts of the car.
