Default Blown hose, any tips on replacing it?

Hello

My Kitten decided that it is time to change the water inn the cooling system completely and it blew a water hose. One minute I am picking up speed nicely (bit over 5000 rpm on the clock) getting to the motorway and the next there is a huge cloud of steam behind the Kitten... Old hoses and high rpm, nice combination.
Anyway, I have found the blown hose, it is part number EAC3454 shown as part number 3 in the pic


Now the question is that is there a good (or even a reasonable) way to get to it to change it, part has been ordered already (as is the water pump gasket). My own guess is that it might be possible to get to it by taking the water pump away and then I might be able to get to the other end too without taking off the intake manifold.

Any advice is appreciated!!

Kay

I've read about the job here but have not done it myself when I had an XJ6:

I had a kit of all hoses, that one included. I changed it with not Too Much Pain by removing that AIR pump. I am not sure yours would have one. I did not remove the water pump. Its just a matter of folding the hose to make it slip over both tubes. By the way, if one hose is gone, you should probably consider doing more than just the one. Good luck!

Hi,

Just a quick update on The Kitten, got the hose changed and it was a quite a job to get it done. Anyhow the new one is place and Kitten is purring nicely, all I am wondering is that should I bleed air out of the cooling system now and if I should what is the best way to do it?

I wonder why the old hose did not work anymore????

Good deal that it's done. What did you do to get at it? "So far" I haven't had a problem with bleeding the coolant. I just keep an eye on it by checking before I go anywhere.

I think the system is self-bleeding, hope so anyway as I've never done anything special to bleed my coolant after a change of coolant or thermostat replacement.

FWIW and Im a little late to the party. Mine developed a leak at number 13 and that required removal of the intake. Which to my point, is that its not that hard and my feeling at the time was since I didn't know the age of any of the hoses I just replaced them all. You might consider planning for that.

Hi,

I just took out some other hoses out of the way and got it done that way....
I am planning to get just about complete "hose job" done so changing the other ones too. But as of now I have enough of bruises in my hands for the moment!!!

YEP. The system is self bleeding. I just completed the cylinder head removal on my car. After the job was done, I filled the system slowly via the coolant reservoir and there are no problems with air in the system.

Oh that water pipe hose...

I replaced mine when I did all the hoses a couple (or maybe a few) years back. It was seeping a little at the forward end. I removed the intake manifold nuts and bolts and all the intake plumbing and throttle body. I was able to get my hands in that way, but the hardest part of the job was slipping the new hose back on. I used a little dawn dish soap in a spray bottle to help lube it up. Some even use two sets of clamps on each end due to this being such a vital hose. Do not skimp on quality here.
