Blown upper radiator hose, what else to replace?
Posted 25 May 2006 - 10:21 AM
So after my last coolant hose incident (see link) I'm ready to rebuild the whole she-bang.
I'm going to do upper and lower rad hoses, 2 heater hoses, radiator, and what else? I'll check out the PITA hose under the A/C compressor, I know if I don't replace it'll go next, so we'll see on that one. Should I do the coolant temp sensor by the thermosat and the thermoswitch on the radiator too? Any other hoses or cooling system components I'm missing? I'm going to wait to do the water pump till replace the t-belts, accessory belts, oil pump & seals, and cam seals.
A compression test is probably in order as well, got my fingers crossed that my head gaskets are intact!

Just pull up/down, left/right on the fan and feel for any movement. There shouldn't be any at all.

on some models i believe there is a very small hose under the alternator (at least on the XT6), it's about center of the top of the motor. replace the hose and clamps on this one. have to make the hose longer than stock if you don't use a pre-bent hose for this one.
there is also a hose at the throttle body, i completely removed it so as not to heat up the air intake. less hoses and clamps as well. route the hose wherever it goes, i forget. depends what intake you have where or if you have this one.
not terribly hard to swing the a/c compressor out of the way for easier access to the hose under there if you like. unbolt it and wedge some 2x's underneath to hold it out of the way. it has enough play to move around a bit.

I pulled the timimg belt covers while I was there, the belts looked good, so I left them be for the time being. I tried to get at the PITA hose under the A/C compressor, but long story short, it remains there, hopefully I'll get at it when the timing belts and oil and water pump get changed.
Now for the radiator. Roos only told me it came off a 90 Loyale, Auto, Turbo. When I compared them it was noticeable thicker, I don't want to say dual core, but beefier, were the turbo rads bigger? When I put it in it was about 1/2 inch taller, so the mounting bolts didn't line up. I pulled it back out, and switched the rubber mounting gromments on the bottom with the original radiator. Put it back in and it still wouldn't line up. I spent most of the time trying to line up the radiator, but it still was about a half inch off. I pulled the gromments off and it lined up perfectly, the bottom of the rad has a little play, but nothing that is too concerning to me.
Test drive was great, temp gauge never hit above 1/4. I flipped on the a/c and ran on the highway and in town with stop and go and it never got above half!!! I went from Denver to Boulder and back for the Memorial Day weekend, with and without the a/c, and she was cool as a cucumber!!! I'll keep my eye on the coolant level to make sure it's full and not using any.
