Thanks for that tip Doug. I'll be installing the later hose for certain now. That way, I can avoid the problem altogether when my engine goes in...

I'm curious: what are the differences between the hoses?

I've got late NA silicone hoses from LR but they do not fit. I've got a late block in an early car. Any ideas?

I installed them in my old 84 with no problem. Radiator mounts will go bad and allow the radiator to sag.

OH NO! A sagging radiator! If that happens, will I have to get a bra for my car? And I just thought it was only for the headlights! LOL!

This, but also buy the Porsche hose, I kept cutting the cheaper uro lower hoses with my power steering pulley in my s2. The hose from porsche direct clears by a mile.

The hose was $32 iirc vs the $17 uro. Worth it.

Edit, the turbo/s2 use a different hose than the NA anyways, I'll leave the post here for future reference, but it doesn't apply to NAs I imagine.

The Porsche late hose is now $90 at pelican and $74 at sunset. That is a mighty expensive hose.

It's just a moulded rubber hose, no rocket science. I got the uro hose for 12 dollars shipped and and happy with the fitment and quality.

Since it's relevant, I did some work today with my cooling system.

I swapped in the new thermofan switch. I couldn't swap in the new(URO) hose I purchased for an '87 944(I assumed any later year would work) because I soon realized after trying to trim it to fit many times, it wasn't happening unless I somehow got a Turbo hose by accident, assuming that it's too different to use.

So I took passenger side 6-blade and swapped it for the 3-blade fan on the original assembly to make the original hose work. Got everything back together not too long ago, bled and topped off the coolant, and even though the head broke off the bleed screw, it's staying a millimeter ahead of the middle tick now. It's no longer overheating in my driveway.

How the heck do I remove the broken bolt screw without it having a head?

Karl..It depends on how much is left sticking out of the fitting. Vice grips might be an answer, but you might have to resort to removing the water outlet fitting, and drilling out the bleeder screw/bolt. If that happens use a left handed bit (yes, there is such a thing) as this will tend to run the bolt out due to the direction of the bit. Once you get through the bolt the first time, keep enlarging the size of the bit, untell there is just a shell of the bolt remaining. Then you can knock the sidewall of the bolt inward, releasing the pressure, and probably remove it with long nose pliers. BTW, you'll need a new gasket for the water outlet fitting. hope this helps some...
