So i noticed my 01 is leaking coolant and it looks like it is coming from the radiator on the bottom corner on the passenger side. but then i noticed the hose running to the firewall and the ac condenser so i am wondering if that front part of the radiator is only for the ac system. my ac does not work so that would be no great loss, but i was thinking i could just remove all ac components, get a smaller belt and it would not leak any more. i might have a small power gain, but i am mostly looking to stop this leak without buying a new radiator. it seems like i can simply disconnect this smaller "radiator" and i should be fine. my question is if i do this, do i need a new heater core with out the two open holes?and will my defroster still work bc i have heard that you need the ac compressor for the defroster, but then how does that all work if your jeep did not come with ac? any and all help would be appreciated.
Whoa......lets separate the issues. Leakage in your cooling system will not be "fixed" by removing any or all AC components. If you have a radiator leak, the only way to fix that is a new radiator.
As far as removing the AC components, you can do so, but you will STILL need an idler pulley put in place of where the compressor sat. This is how the factory did the belt routing for "AC delete". There is NO way to use a shorter belt and get around this.
The defroster will work fairly well without the AC system. It just works better in damp weather with the AC system present.
I don't own an XJ any longer, but I still think they are the best of all the Jeep products ever made. My XJ was my favorite vehicle in my 50+ years of driving.
So...I stick around and give advice.
alright, is the ac in any way connected to a radiator? because it looks like theres two separate radiators, one with the trans cooler lines, bottom hose, top hose and a cap on it, then theres a smaller one in front of that with what looks like a line going into the firewall by the heater core, then there is another hose connected to the ac condenser from that front "radiator"
okay im going to pull the radiator and try to find a hole in that, but when it was running it appeared as if the coolant was leaking from the ac condenser, which makes no sense to me. if i do the ac delete how does the condenser come into play with the heater core? will i have any leaks or just the two open ports sticking out of the firewall with nothing in there where the hoses used to be going to the condenser?
Your AC condenser and radiator have no connection other than sharing the same mounting points.
If your Ac doesn't work, I would doubt any "leak" is coming from the condenser. What color is the fluid you see?
You can *not* use a smaller belt on the 4.0l engine if you choose to remove the compressor. You need an AC delete pulley. There are a zillion threads on it so I suggest you make good use of your favorite search engine.
yeah i knew about the ac compressor having to be replaced with a pulley, the condenser is screwed either way because i had a tree branch come through the grill and mess up about 6 rows of the fins on it, but it did not puncture the condenser. but the fluid was dripping off the bottom corner of the condenser and it was green, smelled sweet, and had flakes of stop leak in it. so i just have to figure out how antifreeze got from the cooling system and onto the condenser.
Does anyone actually make a idler for a 97+? I know people have said they do, but I've never seen one.
I'm thinking a flat 1/8 plate with 4 holes to mount to the AC bracket. Then at the end it comes up 90 degrees and has a pulley mounted on it. Then you gusset the end with the pulley is to brace it. The idea would give you a small flat area you could mount electrical add on's, or a small storage box. Think about having a clean secure place to throw some sandwiches under the hood.
