My lines seem to be shot so I'm just going to rip out the old and replace with new hose. Not a big deal but what about those troublesome check valves? I'm aware of the princible behind the check valve but has anyone eliminated them? I ask because one valve has come apart and rather than epoxying it back together I just assume dump it in the trash.

Thanks

What is the purpose of the check valve?

 

To prevent complete drainage of the hose thus reducing start load on the pump but I have yet to see this on any other car.

You can live with only one: near the hinge of the hood. Makes a good connector piece to allow 2 short sections of tube.

EDIT:
Do not install the check valve reverse!!

I bought both check valves from eurowebparts for under $3 a piece...and they do prevent drain back...so you get spray immediately...

Well worth the small extra cost & hassle, I think. And yes, a single one should work about as well.

If anybody is tackling this job, be aware that the factory hose clamps are one-use crimped clamps, so you have to cut them off and replace them. Save a trip to the parts store by buying the tiny little ones in advance.

Jim, memory too faded by age to recall how many are required...

 

Im living with out one,drivers side.It crapped out so i trashed it,but it still has the other.

How have you been?

I got another ac compressor ,waiting for it to get warm to install,then convert it to the new stuff.

 

Hey Paul, I'm doing good & you? Gonna go with the 134a this time? Let me know if I can be of any help or if you want to stick with the R-12we can always try it again.

I think Im gonna go for 134 this time ,my luck this is going to be a recurrent problem!Until I break down and get a new compressor.Cross you r fingers that this one lasts more than 1 summer.
Stay in touch,maybe we can have a gathering in southern NE. Im thinking of contacting the TOOLMASTER and arranging an" adjust your timing belt day" when the weather gets warmer.Anyone around RI interested? Next who else is an "expert" to help teach all of us?
