Cosco Buckle Broken

You should be able to download the instruction for this model from this site
Instruction Manuals

You will have to remove the buckle loop holding the harness at the back of the seat and release the straps. Once you insert these through the seat cover and back into the slot on the seat back you can lock the harness by re-inserting he buckle loops.

You should see a harness strap over each shoulder that goes though the shell, behind the seat, and connects to a metal splitter plate.



The front of the harnesses (2) extend down though the buckle tongues then into the hip area of the seat.



There is a crotch strap that comes out of the shell where the child\'s crotch is. The buckle is attached to this strap.



There will be a LATCH (Lower Anchors and Tethers for Children) strap that goes through one of two belt paths. If used, this strap must go though the proper belt path.



Finally, there is a top tether strap the comes from the back of the seat - near the top - that will attach to the tether anchor in your car (see your car owner\'s manual)





My suggestion to you is to purchase a new seat. The protection of your child is most important.

This will help if you lay out the chest pieces and all the pieces you removed on the table first. If it helps, snap them together. Then, lay out the pieces with metal prongs that lock into the buckle that goes between your child's legs.

1st pull through the belt adjusting piece through the bottom cover ****.

2nd pull the square release buckle through the second ****, on top of the piece that tightens and releases. This is the piece that you push with your thumb to release the seatbelt.

3rd pull both side seatbelts through the respective side right and left and make sure they are flat.

4th slide on the two pieces with metal prongs on one left and one right seatbelt. Before you do this, ensure that you have put the correct piece on the correct side and that they will latch properly into the buckle. Snap them into the buckle to ensure you have it right.

5th attach the two respective chest clips on one right and one left seatbelt. Snap them together to ensure you have it right.

6th pull the top shoulder seatbelt straps through one of the top cover slits. If you have a newborn, then it will be the bottom **** at the top. If your child has grown, then it will be the top two slits. Ensure both seatbelts are pulled either through the same **** on either side.

7th after you have pulled the shoulder straps through the top slits on the cover, pull them through the slits in the plastic carseat frame. Pull them through until you see them at the rear.

8th attach on their respective sides the shoulder strap at the back of the plastic carseat. There is a big brass metal piece with "hooks" at the top. The shoulder strap has a seatbelt "loop" on one end that can be hooked on. Do this on each respective side and make sure it is secure.

Contact the manufacturer. They ought to email you a manual within minutes. Manuals for car seats are very important, so you'll know when your child outgrows it. In my car seats, the harness is hooked on the back to a metal buckle-looking thing that is attached to a piece of webbing. The webbing goes under the seat and out the front, where you pull on it to adjust the tension. Simply remove the harness straps from the buckle-looking thing, pull out the front, push through the higher harness strap position, and reattach to the buckle-looking thing.

turn the seat so you are looking at the bottom, insert the strap- one end on each side- turn the seat in an upright possition facing you, put the buckle pieces on appropriate side, attatch the center piece- at the chest- insert the strap into the appropriate slot- the adjustments- now turn the seat so you are looking at the rear of it, attatch the metal retainer.

Well.. I really could use some more info about how the carseat looks but thinking todler if it is the largest todler one you should just put the seat belt over the childs arm and waist and buckle regularly. If it is the one with the pull down plastic piece. you run the seat belt through the first side put your hand in the other side get the belt and pull through the last side then buckle.

Please right back and let me know if this helped :)

I know this is months later, but here you are in case you (or anyone else) needs the info again. First, though, I feel that it wouldn't be responsible to neglect to tell you that if you got the seat in 2000, it is expired and no longer safe to use. Car seats generally expire after 6 years because the plastic degrades over time - in a 10 year old seat, it can look fine but actually be brittle enough that the entire harness can rip out of the seat if it's an accident. For the manual, visit Cosco's website and fill in the product number and date of manufacture. It will bring up a PDF file of the manual that you can download. To rethread the straps, first replace the **** strap. Slide the metal plate down through the slot in the seat, with the buckle facing out. Slide the metal clip under the tab and push it down to lock it in place. Facing the seat, start by threading the end of the harness strap down through the slot of the left side of the bottom (where the child's right hip would be). Under the pad/cover, thread it across the bottom of the seat and up through the matching slot on the right side. Pull it until you have equal lengths on both sides. Thread the buckles onto the the strap (one one each end) and buckle them. Thread the chest buckle onto both ends, making sure that the harness doesn't twist. Buckle it, too. Push the ends through the harness slots. Pull the harness through to the back, making sure that it goes OVER the metal bar, but UNDER the plastic adjuster handle. There is a loop sewn into each end of the harness. The adjuster strap has a splitter plate, kind of shaped like a Y. Slide each loop over the ends of the plate and all of the way into the slot, so that the curved ends of the splitter plate are exposed and the strap is secure in it's slot. Adjust the harness height by squeezing the metal bar on the back of the seat (the one behind the harness) forward and moving it and the plastic adjuster bar up or down to the correct position (at or below the shoulders for rear-facing, at or above the shoulders for forward facing). Do note that the very top slot is NOT for use with the harness - it's only to adjust the headrest when the seat is being used as a seat belt positioning booster and is not reinforced to support the harness in an accident! Adjust the tightness of the straps with the button/extra length on the front of the seat. Properly tightened straps should lay in a straight line without sagging and you should not be able to pinch up any slack (lengthwise going down the harness, not across the width of it) at the shoulders or hips. Adjust the chest buckle to lie in line with your child's armpits, never his neck or belly.

The straps need to be removed from the metal clip in back, and then the plastic grommets must be pried loose from under the fabric with side pressure and an upward push. Its not easy. Bad design. There are no screws involved, but a standard screwdriver can help with the release. The oblong grommets have ridges that must be compressed to release.

ok I had such a hard time with this, i looked on the internet for hours and found NOTHING!! haha so i went to babies r us and checked out a similar one so here it is.
first the strap goes on the bottom, pull them even and the add the buckle, plastic buckle thing, and the other thing soft thing. then put the strap through the back of the seat (you should have two ends) not the must go OVER the adjusts! now take the metal piece that adjust the length and pull it long enough for it to reach the two straps and hook them up!! haha if this isnt good enough go to a store that carries the alpha omega elite car seats and check it out! GOOD LUCK!!
