I always refer to it as tar tape, I am sure there may be another proper name for it. But at least I think the guys at the counter will know what I am talking about as the tape looks like tape made of tar?

Mtndewnut,
Does your D have electric fan assist for your A/C? wrapping your return lines will help. You may want to check your fan clutch. It may be getting weak turning the fan when the engine is idling, thus why your A/C is not cooling enough when your D is not moving.

I have to find a electric back up fan for my truck. I bought one but it's TOO big to fit in the front without hitting the front clip when I shut the hood. I measured the distance between the clutch and the radiator and I only have about 1 inch so I can't put one there. Anyone have an idea. I have to get my ac cooler as well as my motor when it's hot outside and the a/c is on.
I did have a big electric fan tho. Anyone have a replacement name, size, and part number?

I am sure there should be plenty of clearance between your radiator and the clutch fan to put in a slim 15 inch fan? Unless the 98 models have tighter clearances compared to the 2000 and newer models?
Otherwise, I guess you should go with that Mark III fan that Indy got everyone tickled over!

Just wondering if you wrap the lines with an aluminum backed tape, the kind that is used in HVAC, that also has a fire rating and is made for high heat applications, if this would work as well instead of the tar tape. Any thoughts?

The stuff I picked up is aluminum backed and is thick so it will keep the cold in and the hot out. Keep that in mind.

The "tar tape" is also refered to as "cork tape".
M.G. good job on insulating the suction lines! Don't insulate the liquid lines it won't help, it will actually hinder the system. The liquid lines (the ones smaller in diameter and hot to the touch) are generally around 30Deg.F warmer than the outside air in a good functioning AC system.They need to be not insulated because they are giving up heat to the outside air as they are intended to do.The benefit you got from insulating the suction lines besides the reward of cooler air is compressor life. After the refrigerant leaves the evaporator it still has capacity to take on more heat, it's other job is keeping the compressor's temperature under control, by insulating the suction lines you increased the cooling capacity system wide and now your compressor also runs a little cooler than it used to and should live a longer life as a direct result.Good job. I'm gonna do mine too, after I replace a bad expansion valve for the rear evap.
Another type of tape one might consider is header tape, I'm think'n of wrapping my lines in cork tape first and then in header tape to protect the cork tape.I can't think of any type of tape that can withstand more heat than header tape.

i just wrapped mine in pipe insulation (59 cents for a peice 4 feet long) and tied wrapped it on the cold side ac really cold (did the same on my caravan years ago) my my d freezes you out
and just in case someone asks (no the pipe insulation did or does not melt) ran like this for 2 months, then just for looks I bought some aluminum duct tape $2 and wrapped all the pipe to make it look nice rater than seeing tie wraps
so for $3 canadian I now have to open the window once in a while to warm up, even my wife turns it off all the time causes it is tooo cold and rolls down the window when it is 90 degrees outside LOL!!

I just got done working on the AC..............ALL DAY!!!!!!!
I got the new compressor on and pulled a vacuum and charged it last night.
I wrapped the cold line form the Compressor to the firewall and then also the cold line that goes down and under that merges into the top line. I got about 6"-8" down, and couldn't reach anymore. It's a pain where all those lines are against the firewall. I used some 1/4 inch foam insulation tape that has metal backing. Only $4.50 a roll and went through 1 and a half rolls. Then I went over it with this super high temp foil tape. It literally looks and feels like aluminum foil except it is SUPER sticky on the back. I have never seen anything this sticky before. It held to anything it touches like a champ!!! Nothing is going anywhere.
But then I also made a heater core bypass manifold. That made a big difference in the cabin. No warm air at the feet. Very easy to use, kinda pricey though. I just got done with the cold air lines, so I haven't got to test them out yet. That's tomorrow. Hope it helps mine as well as it did Means!
Now, when I finally get my electric fan, I should be roll'n Frosty Style for sure!!! When I put the fan on I'm going to do a "custom" cold air intake Mean Green Style! I always wondered about the "custom" CAI in your sig....Then I saw the thread yesterday....I love Ghetto mods!!!

Yeah I do too, as long as they're cheap (the wife wouldn't have it any other way) and function well I'm all about it. There waws some company on ebay making ramair setups for the newer Rams and I believe the Daks, It is the same concept as mine but it looks refined whereas mine looks ugly. Only $50 too. I wonder if they ever fulfilled their promises to make the same setup for our body style Dak/D's.

Hey Mike, awesome idea on wrapping the a/c lines... I'll have to go take a look at mine here shortly. One thing you definatley should do though is get the thermo-tech insulating tape & wrap your fuel rails. this will keep the rails from getting heat soaked and heating up incoming fuel. I did this on my ram (along with the cooler) and it helped out some with fuel economy (6% better on the hiway).

Are the fuel rails the 2 black rails on either side of the intake? What all do you need to wrap on them?
