coolant bypass hose
« on: October 22, 2007, 19:48:09 »
Is it possible to remove and replace the coolant bypass hose located under the thermostat housing without removing the air conditioner and alternator bracket? If so, how is it done? Your help would be appreciated.

Hello twoods,

I am sorry to tell you that it is not possible to replace this hose if you are dealing with the original AC bracket. Removal of the AC bracket is a real task.

Is this just preventative maintenance or do you have a leak?

I have a leak and it needs to be renewed. I thought this was the case but I needed a second opinion because it is difficult. Thank you for your response.

Yes, like Joe said, it's a really tedious a job.

However, if you do decide to take things apart, it might be an excellent opportunity to replace a whole slew of cooling-related hoses and gaskets in that area.

This would be a good time to replace the water pump too, The A/C belts and tensioner places a lot of extra load on the water pump bearings.

You explained "Jonesing". Now what does "a cheesin" mean?

In the mid-70s, mid-western, urban vernacular that I am referencing, it seemed there were 3 states of "be"

a-Wiggin'; Angry (flipped his wig)
a-Cheesin'; Happy, smiling, (say cheese)
a-Jonesin'; Desiring, craving (keeping up with the Joneses)
I imagine there were others too, but these were the ones that Jack the porter at our shop used the most.

So far I am quite pleased with the results of the new fuel tank installation.
