Had to replace the upper radiator hose AND the ignition key lock cylinder today.
I should have replaced the upper hose at the same time that I replaced the water pump over the Independence Day weekend (see my previous post on this topic), as I had noticed it was swelling like a balloon, but I figured it would last a few more days.
And it did.
Then it ruptured like a balloon this morning. Lucky for me, it was AFTER I had dropped the Wife off at her job. Also lucky for me, I had bought a new hose the day before at Autozone. The new hose was a Dayco brand, part number 71654. About $15 but NOT made in China.
Replacing he lock cylinder was easy-peasy, but the radiator hose pointed at a different angle than the radiator inlet on top. This being due to a dual core radiator from a 4.0 being installed under emergency conditions three years ago. On a summer holiday as well!
Anyway, in order to get the hose end to line up with the radiator inlet without bending or kinking it, I cut off about one inch from its straight section, reversed it, then rotated it 180 degrees. I coupled it back to the longer part coming from the thermostat housing with a short piece of thinwall copper tubing, sealing both sides with a blue gasket maker (NOT Permatex.) This allowed the hose to mate with the radiator inlet at its preferred angle. I used stainless steel hose clamps all around.
This coupling is now directly UNDER the air intake tube.
Ran the engine to normal operating temperature until the thermostat opened (the temp gauge makes a sudden drop from the 12 o'clock position to the N in NORMAL), then took it for a short test drive around the neighborhood.
Happy to report no leaks!
I am not sure if this will be a permanent solution...perhaps the proper fix would be to install the radiator for a 3.0 so as to avoid these hose modifications.
We'll see how long this lasts...
Sounds like my “upside down and backwards but works” theory is catching steam. I’ll consider you for a junior shed of miracles award.
