  1. Do you still have the Early Eliminator silver body decals? Like the ones in this picture for the front doors?
  2. I lost one of my front door trim panels/strips from the glue peeling back and the wind caught it one day. Please let me know if you have one you are willing to sell. I've had trouble finding one online.
  3. Agreed. Two of the outer mounting brackets do not line up but the mounts using the rubber grommet lines up just fine which is enough support for the radiator. My Jeep hasnt had any issues with this setup.
  4. The electric fan is stock wiring. The fan +12V wire comes from the secondary fan relay. The ground wire from the fan goes to ground. The coolant temperature switch located on the radiator is what switches the relay on/off. To re-purpose the coolant bottle, the 5/16" line coming from the radiator overflow line by the radiator cap was routed into the bottom of the bottle. I managed to find a rubber grommet that fit in the bottom of the bottle and was about the same outside diameter as the hose. So, I inserted the 5/16" hose into the grommet with some Seal-All and then pressed all of that into the bottom of the bottle.
  5. Review on Krusty's Hitches. I must say this man does an awesome welding job. The fabrication and shipping was very fast. No damage to the hitch when I received it. The hitch also came with new bolts. I painted the hitch with POR-15 rust proofing when I got it. That is some great stuff by the way. All the dimensions were within spec and everything went on good. Thanks Krusty!
  6. Hey all, Here is the model and information you need to know about my Jeep. 1989 Jeep Comanche Eliminator, 4.0L Straight 6, Automatic Transmission, 2x4, I have A/C and cruise control. I have managed to complete my closed to open cooling system conversion. I did not spend a lot of money and I also did not go the cheapest route. I shouldnt have to replace any more water pumps or worry about cooling ever again. Here is a list of components that I bought: //////////////////////////////////////////////////////////////////////////////////////////////////// 2-Row Radiator - $100 https://www.amazon.com/gp/product/B01EVWTXLY/ref=oh_aui_detailpage_o09_s00?ie=UTF8&psc=1 Quality: 8/10 Functionality: 10/10 Comes with elbow and straight radiator cooling line fittings. Radiator Cap - $35 https://www.amazon.com/gp/product/B01F93S3E2/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 Quality: 9/10 Functionality: 7/10 It is very hard to turn on and off the radiator. 4' of 5/8" Black Heater Hose - ~$15 total Autoparts store 4' of 3/4" Black Heater Hose - ~$15 total Autoparts store (2) 5/8" to 3/4" Hose Adapters - ~$15 total Autoparts store One Gallon of Concentrate Coolant - $15 Autoparts store One Gallon of Distilled Water - $3 High Flow Thermostat Housing - $33 http://www.hesco.us/products/7882/cooling-system/133247/hi-flow-thermostat-housing-hfth2#.WRuBvWjyuwU High Flow 180deg Thermostat - $19 http://www.hesco.us/products/7969/thermostats-and-housings/43013/hp--gmfordamcjeep-thermostat-180-degree-4364#.WRuIYGjyuwU Thermostat Housing Spacer - $37 http://www.hesco.us/products/7969/thermostats-and-housings/43017/thermostat-housing-spacer-hesths#.WRuIiWjyuwU High Temp Blue Silicone Gasket Maker - $12 Autoparts Store Hi-Flow Water Pump w/ Gasket - $87 https://www.4wd.com/p/flowkooler-high-flow-water-pump-natural-1747/_/R-GNLS-1747 Hose Clamps - ~$10 Autoparts Store 6' of 5/16" Hose for Radiator Vent - ~$10 Autoparts Store (1) 5/16-18 by ~2" long (1) 5/16-18 by ~1-1/4" long *Not exactly sure on length because I gave up on using the housing spacer (I will explain later) *The housing spacer and thermostat housing comes with gaskets. Total: ~$396 Well worth it, will never have a cooling issue. Works like a charm. My Jeep is preventing global warming from happening. //////////////////////////////////////////////////////////////////////////////////////////////////// A few pictures of stuff I bought... Start taking off parts... I had to take off the supports on top of the radiator, loosen the belt, and accessory fan. See photo below. NOTE: See the square rubber supports on top of the radiator? You need to reuse those. Take them off and put them on the new radiator so you do not forget... :doh: At this point I drained the coolant and took off all the hoses and transmission cooling lines. There is no pressure in the transmission lines so no fluid should leak out! Here is my old radiator taken out of the truck. This also shows the fitting types for the transmission lines. See the bottom elbow transmission fitting? My new radiator came with a replacement. The stock one is one piece and not a swivel fitting like the new fittings. You MAY have to grind, file, sand, etc. the diameter of the new elbow fitting so the plastic quick disconnect fitting will slide on the new fitting. Either that or you can file the plastic piece like I did. See below. ^^ That plastic piece goes on the elbow fitting ^^ I found that there was two holes that did not line up to support the radiator...Both sides. So I zip tied them on. Not too important since there are other brackets supporting the radiator on the top. First issue I found with the housing spacer... The belt comes pretty close the to lower housing bolt. See below. Also you can see two brass inserts. That is a 1/4" plug on the right (wrapped in teflon tape) and 3/16" plug on the left. Normally sensors go there on the newer jeeps. The Renix older jeeps have the sensors elsewhere. Second issue because of stupidity (Halfway my fault). Hardware store worker said the housing bolts were M8-1.25. They are not... They are 5/16-18. So I stripped out the holes and the bolts. I said screw the spacer and used original bolts. Bad luck for trusting the hardware store kid. :fs1: A little fabrication was needed for the radiator cap on the support bracket. It comes pretty close. Also, the vent hose is a 5/16" hose. I re-purposed my coolant reservoir bottle for my overflow tank. I forgot to take a picture but the two heater hoses go straight into the heater core. This shouldn't affect the A/C as the heater valve is open when the A/C turns on. This info is straight from the Jeep service manual I have. Heat comes out of the vents when the blower fan isnt on which is the only case which could be bad... Heat could build up without the blower fan on and melt/overheat things in the HVAC. Other helpful things to note: Make sure to put fan belt shroud/cover on before the new radiator is in. Make sure to put the rubber supports from the old radiator onto the new radiator. !!!!!!!! LET THE SILICONE CURE BEFORE FILLING THE SYSTEM WITH COOLANT !!!!!!!! Feel free to message me for any questions about my experience with this upgrade. :cheers: :rock on: :clapping: :waving: . :MJ 2: .

  8. Check out my DIY booster swap in my signature. It outlines which ends are bubble and standard flared.
  9. If you haven't already... click on the link in my signature for the dual diaphragm brake booster upgrade.

  11. what was your way of purging the air out of the system? I usually start the engine and let it warm up close to operating temp, shut off the engine, let it cool a bit till the radiator is 'warm". then open the radiator cap. Repeat maybe one or two more times.
  12. Upgrade your ground cables!!! Recommend doing the WJ/XJ brake booster conversion. It makes your stopping power so much more. Replace the hard vacuum lines with rubber hoses of the same inside diameter. Use POR15 rust proofing on the rear of your frame, bumpers, and rocker panels. Expensive stuff but works amazing. Duck tape your spare set of keys on the connector for the rear lights! I do this because it looks like a terrible electrical job with all the tape but if you ever lock your keys in your jeep all you have to do is go underneath the back to the connector, rip off the tape, and you have your spare set with you!
  13. This^ Tires deform due to the weight they hold. To more accurately find out your vehicle speed you need to measure your dynamic rolling radius. Then find out your current RPM, the gear you are currently in (if you are in OD then use that...), and the differential gear ratio. MULTIPLY... (RPM * 2 * 3.14 * 60 * [measured tire RADIUS in inches]) to get your inches per hour. Then DIVIDE that answer by the transmission gear ratio, the differential gear ratio and 63360 to convert inches to miles. (RPM * 2 * 3.14 * 60 * [measured tire RADIUS in inches]) / (Transmission Gear Ratio * Differential Gear Ratio * 63360) = MPH The final answer is your actual vehicle speed in miles per hour. I found that my GPS was pretty accurate to my actual vehicle speed since I also have bigger tires on my truck.
