68 L-79 Upper Rad Hose

[Richard D.]

Question on this molded upper rad hose for a 68 L-79 (Manual trans, no A/C, power brakes) -

Is there a slight built in "trap" (like a sink trap) at the point where it attaches to the upper radiator connection to prevent an air pocket from forming in this hose and compromising the coolant flow in the system? My guess if that if there is, it would on the same level in the engine compartment as the lettering in the middle of the aluminum fill tank to maintain proper fill level.

Would assume that all the reputable suppliers of molded, correctly configured GM marked hoses would be from the same supplier, just wanted to double check this, as it seems I keep getting some kind of "air lock" in this hose on my car, and need to manually massage it to fill it (the hose that is) to make sure the flow is good through this hose.

Thanks in advance for any feedback on this, and if anyone has a pic of a correct hose on their 68 L-79, I'd appreciate it.

Regards,

Rich

That double bend in the upper hose is for clearance to the alternator on PS equipped cars. I believe at the start of production there was a different configured hose for non-power steering BB, and that hose was used on PS cars only. Sometime during 1969 production all BB used the double bend configuration.

Rich,
E-mail me with your e-mail address and I will send you a picture of my hose on my stock 68 L 79.
I have the power steering so if you do not mine may be different.

Rich,
I forgot to mention, I also have A/C so therefore I have the copper radiator , not the aluminum one in case the hoses differ for these radiators.

Thanks guys.

I have the DeWitts rad in mine (correct for the car, put in last summer).

And thanks Kurt, I saved the pics you sent me about a week ago, but your rad is different, but I appreciated your help.
