Did you pick up 90 degree swivels or just hard 90’s?

Figuring two for the transmission to -8an
two to the radiator to -8an
and two for the front cooler.

I'm probably fine with what i have, but I really hate to not have enough when the time comes.

Were you able to get it to relearn without taking it in? I’m guessing you don’t have Tech2 or an OBD tool capable of doing a relearn?

I could be wrong, but I think a big part has to do with the fact of disconnecting the battery prior to disassembly.


Very true…but regardless by the end of Feb the weather has to be better than anything we have in Michigan.

nope never disconnected the battery, plug-n-play if the engine is off there is no power to the throttle body
when cleaning I have always cleaned them by hand with spray cleaner and rag, I don't push on it hard enough to bend the butterfly but enough to get the grime off. just hold it open all the way and clean all sides and what can be reached inside the intake i always clean the maf at the same time.

I’ve done the same thing, as well as removed it and cleaned it and then reinstalled it. Never a problem.

That’s the first I’ve ever heard of anyone not unplugging the TB or unhooking the battery when cleaning or changing them out.
I’m curious now…why do you guys think others are running into issues with needing to do a relearn (by that I mean taking it in and having it done)? Is it the difference in OEM vs. aftermarket parts, specific years not relearning as well compared to others, or maybe not giving it enough time to work out the issue?

Anyone running a Melling water pump? What did you think of it compared to OEM and are you running Melling gaskets as well?

I have no idea. Maybe they’re turning the key on when it’s out? All I know is I’ve never had to do a relearn. I unplug them when I take them out, then clean them and put them back in. There’s no voltage going to them unless the key is turned on. Or turn the butterfly by hand wide open and clean it.

I’ve thought about rigid foam cut to shape and wrapped in black fabric. Friction fit from the inside.

I used some foam insulation board from Home Depot for a different project a couple of years ago. About 3/4” thick and real easy to shape. Easy enough to stick in place with some Velcro.

I do the same with no issues.
