TOPAZ 52079753AB Auto Transmission Oil Cooler Line Compatible with Jeep Grand Cherokee 2000-2003

So when replacing the radiator on my 20023 Jeep Grand Cherokee Limited (4.0L), the original lines were so stuck that even a vise, PB Blaster, and heat could not separate them. Some forums said to just use a hose but the threads on the radiator did not match any brass parts at the hardware store. At my local discount auto parts store, these lines were just under $100 EACH. This set of BOTH cost about 30% of the cost of local, and being a Prime customer I got them in less than 2 days. They fit perfectly. And since these are not high pressure lines, I have no worry about their ability to last. The ones I got had some German manufacturer name on them, and they seemed quite sturdy, easily as sturdy as the ones I tried to remove. I guess you could use some type of pipe dope on the threads so they wouldn't corrode and get stuck, but I didn't bother. These are a flare fitting.Also, do yourself a favor and buy new rubber hoses and clamps. No reason to spend all this money and have a cheap piece of hose ruin your job. I had some of this hose left over from installing an oil cooler on my other car and it fit perfectly: https://www.amazon.com/gp/product/B000HE6H3S

When replacing the radiator on my '99 Jeep Grand Cherokee, I found the existing transmission cooler lines were completely frozen to the threaded inlets on the old radiator. Trying to remove them actually twisted and ruined the lines, so I ordered this Topaz kit. The new lines fit perfectly. I very carefully added a little anti-seize to the threads of the inlet ports on the new radiator just in case I need to remove the lines some time in the future.

Bought this product even though it is for the 4.0 Jeeps. My 2004 Jeep GC WJ with the 4.7lHO with the 545 RFE broke the lines when I replaced the radiator, and I needed a product fast. This was going to arrive the quickest, and was also the cheaper option. The two hoses fit and work, not leaking, the length is approximately right but the bends in them are the issue. The shorter lower transmissions cooler line isn't as much of an issue, its the longer one. I had to un-bend some portions so the line would fit over the sway bar instead of under. It worked if you are in a pinch and can't find another one.If you can wait, Amazon sells the lower line, and the upper can be bought on Rockauto (which shipping is sometimes long).

This was the part that stopped my jeep from leaking red fluid after I replaced the radiator. The old one started to rust and was not making good connection at the lower connector coming from the transmission. Tight area to work at but it can be done with a 7/8 wrench, a flashlight, and patience.

The original listing stated that the cooler line kit would NOT fit my vehicle. I went back to my Jeep and looked at my lines (2 of them) and they looked to be a match. They were!There is only one way to replace both of them and that is to remove the radiator. Excellent fit! Exact match as the originals!

A little expensive but exact copies of OEM Jeep, good bends, and a perfect fit hugging the radiator as needed .There is little room on a Grand Cherokee to work when installing so every thing better be correct.

Worked like a champ. Built like OEM. Received quickly, installed with no leaks. All the bends in the tubing matched original so hose connections were simple.

This fit perfectly on my 01 jeep Laredo!
