Another newbie question (overflow bottle)

I fear being booted from the site for continuing to ask silly questions, but believe me when I say I jumped into this truck with ZERO automotive skills.

I'm in the middle of replacing radiator, thermostat, and fan, so far so good. Just waiting on a fan spacer and trying to find a lower radiator hose that will fit...the standard hose appears to be half the required length!?!?

Here is the question. I am installing an overflow bottle. Does the hose from the radiator go into the bottle or does it clamp onto the neck of the bottle? I'm guessing it goes into the bottle and then clamp off the neck.

Thanks again.

There's no such thing as a silly question.

You're correct. The line needs to go to the bottom of the bottle. What I've done before that works good is to slip a piece of steel tubing into the end of the hose and bend it so that it goes down to the bottom of the tank.That way the clamp will seal the tank nipple against the hose but the tube will keep it from getting pinched off.

Only dumb question is one asked at work , on friday , just before quitting time .

Correct , insert all the way to the bottom of bottle so that the coolant will be drawn back into the radiator as it cools. I just secured the hose with a hose clamp at the neck.
Be sure that the end of the hose does not seal against the side or bottom of the tank , I cut at a slight angle on the bottom of the hose to keep this from happening.

What is up with the lower radiator hose ? Is the outlet fitting on the radiator on the proper side ?

Is the water pump the correct one ?

Did you save the old lower radiator hose , take it with you to the parts house.

Do you still have the old radiator , are the ins and outs in the same location as the new one?

I cheeted, when i replaced my cooling system about 2 weeks ago ( water pump, thermostat, hoses, radiator, new fan schroud, and a new fan) I whent to a Upull it and found a overflow tank from a 80s chevy truck and mounted it infront of the winshield wiper fluid tank. It fit perfectly over the top of the horn, just had to drill two new holes for the mounting pionts ... The tank I got has the intake on the bottom... I wanted to use a WH overflow tank but found that I was running out of room on the passenger side inner fender with battery, battery manager, MAF and air filter ... Send me a pic of your bottle, would love to see your set up .....

I'll describe with all directions FACING the engine compartment.

Not sure if it is the right water pump. The top hose connects to radiator on top right, the bottom hose connects to radiator from bottom left. The original setup had the bottom hose running under pulleys/fan connecting to a section metal pipe that was connected to the water pump by a 4 inch section of hose. The factory hose would never reach? I'm wondering if the original radiator had the bottom hose coming out of the bottom right side of the radiator? I have the hose I took off but have not been able to find a replica.

I got the radiator, shroud, and bottom hose from Tom's. It makes me wonder if the water pump is different..ie the bottom connecton on opposite side.

That's what I was wondering also.
I know serpentine driven setups run backwards compared to our older units and have the water intake on the other side of the pump than the older ones.

Otherwise everything else sounds right ....

Except the lower hose having a section of pipe in it . Sounds "custom" , but I may be wrong.

You could always just go without one. My Bronco is 38 years old and has never had one. I've worked on several Bronco's that never had one either.

I can still kick myself for not putting one in sooner. I went for 15 years without one. I got tired of constantly topping off my radiator every few months so finally installed one. It makes quite a difference with better heat transfer because the system is always full. Temperature swings are smaller, ~180-200 deg. I used to get near-over temp on hot days in stop and go traffic. This no longer is the case.

its true that the older Broncos didnt have one, but its a real nice upgrade to know the systems topped off and someones dog isn't lapping up your coolant spill.
