Note that the straight V8 water outlet is for the later LA engine, starting around 1985?? For example, I know you can ask for an outlet for a 92 Dodge van/pickup with a 5.2L engine...

The straight water outlet appears to have started in '68 actually, though it was used only on cars with factory A/C for the first few years. The '68-'78 unit is for a larger-diameter thermostat than is used on the \6; the '79-up item takes the 2-1/8" thermostat correct for the \6:

Four Seasons # 84909, listed for '79-'92:

There is also the one for the '92-up (Magnum) 3.9/5.2/5.9 V8s, Four Seasons #85181. It looks to flow more and weigh less (it's a racing thermostat housing!), takes the correct 2-1/8" thermostat, and has the correct 1½" hose diameter:

Thanks, Dan. I did not know anyone made a stamped steel version currently.

Ok, this just hit me, I had to take out my coil in my lower radiator hose to accomidate for the weird angle on the outlet on the radiator. Will this have any negative effects. I've heard both sides from it will be fine to, any rpm over idle and it will collapse, I want to know before I start driving it. I could put the coil back in but it will be a pita to to do so.

Thanks,
Seth

Using support coil all depends on construction of hose. Some newer designs are such the now coil is not needed, while other hoses need the support. If your hose is quite stout, and resists collapsing when hot & squeezed it may be fine without a coil.

If you see that temperature is higher than previous to new radiator install, than coil most likely need to go back in.

I used to think that coil was important, til I did some research on why it was there and why it's been discontinued from most current-production hoses. The coil was there so the hose wouldn't collapse during the vacuum-and-then-rapid-fill cooling system fill-up procedure used at the end of the assembly line. Once the car is operational, the only reason why the lower hose would tend to collapse is because of grossly excessive pressure drop across the radiator (i.e., the radiator is clogged). This is the case even if you are running an exotic coolant (the waterless type I use) which does not operate under pressure, and it is even more the case when you are running with a normal pressure cap that tends to keep all the hoses well "inflated".

Soooo, if no coil and you get lower-hose collapse, service the radiator!

Thank you Dan for clearing that up!
