Red Fluid?

changingtime · **Posted:** Thu Dec 16, 2010 9:56 pm

found a wet spot in the garage after it sat for 3 days. Stuck my head under and found one of the rubber lines near the radiator (behind/under) soaked in red fluid? thoughts?

definitely from under the radiator, i believe the condensor is in front of the radiator and don't see any leaks.

Transmission fluid cooler? It's integrated with the AC condenser.

hm, i don't see any leaks around the tranny...so, I figure it's one of the lines coming from it. the line that is wet goes under the engine...any ideas?

Maybe your lines need to be replace check carefully they are expose so they rust , I change mine last summer (52Kmiles) after 5 years of winter driving in salt and calcium...

Expensive to replace...

Well you only have 3 items that have red fluid in them,the trans,power steering,and t-case and it's not the t-case.If it's a line that goes under the radiator it is either a trans cooler line or PS cooler line(if you even have one).All trans cooler lines(and oil cooler lines,super common issue on Chevy's with oil coolers) that have metal crimped to rubber are well known to leak sooner then later at the crimps(not just a Jeep thing either,all makes).

had it checked this am. trans line from the front of the trans to the radiator. (confirmed) I see someone posted a part number, but there are two lines...I want to replace them both. would i just buy two?

of course there is a new part number and it's 95 dollars now: 55037734ad

Have you check the page of the parts list manual I suggest you? I guest not because you dont know the lines are not sold separate and got a unique part number for both.... :wink:

Download the manual here on this forum and you find out....

PS : Last 2 letters is just a revision, it alway's came with a new higher price tag from the stealer...

Unless you know someone who has the xxxxxxxAC part number, I have to pay more. I've called a couple places and they can only get the latest revision, including the website you provided (I called them).

and thank you for supplying the part number...you made the ordering much quicker for me
