So I decided to replace my radiator, and combine that with some other little things I had on my list for a long time. Most importantly those sweaty tranny lines!
The XJ has a separate oil cooler riding in front of the rad. Actually, that's another question I have: should I replace the tranny cooler also while I am at it?
So here's what I make of it. From the back (tranny) there are two steel lines coming in, connecting to rubber tubing, one going into the top of the rad (inflow, right?). Then the bottom hose on the rad is rubber (return hose?) that goes into a steel line that connects to the oil cooler. Steel line coming out of oil cooler connecting through a rubber hose to the steel return line going to the back (return to tranny). Or do I have the whole thing upside down?
All the rubber hoses are wet (tranny oil), probably leaking from the connections. I think it best to just replace the whole lot of them. Reasonable thought? The connections are a mix of what seems permanent connections, quick connect (a little like the ones on the fuel lines hooking onto the injector rail), and regular hose clamps. So how do I best go about that? Can I just use regular rubber tube and hose clamps on all, or are there nicer ways to fix this? Are those permanent-looking connections easy to remove? How much pressure will be on this system when running?
Further, while I pull the radiator I was thinking also to replace the serp belt and the (missing) fan shroud.
Anything else I might wanna consider doing at the same time? (I recently replaced the exaust manifold, water pump, hoses, and t-stat; the fan clutch is still good)
Thanks for any thoughts! Sorry for the exhaustive post and the myriad of questions.
