Exclamation 2000 chevy malbiu radiator replacement
i am trying to repair my 2000 malibu on my own. my radiator is busted and i removed it and went to the junk yard and got one off of a older model ( must of been a 98 or 99) and when i got it home i realized that it was missing one of the hose hookups on the radiator . on my radiator there was 3 hose hookups on the passenger side and this radiator only has 2. on my overfill tank it has a little hose at the top and i have a hookup for that and on the bottom of the overfill tank it has a medium size hose at the bottom and there is no hookup on the radiator for it. what should i do? the overfill tank was already gone off the car at the junkyard and i wandered is there anyway to safely make this radiator work? thanks!

I think that if you look carefully you will find that only one hose from the recovery tank actually goes to the radiator. (most hook right below the radiator cap) The second hose is probably an "Overflow / Vent" hose that just hangs down beside the recovery tank.

If the radiator doesn't have a pressure cap and the cap is on the recovery tank then both hoses will likely have to connect to the radiator & you will need to get the correct radiator.

Please let us know what you find.

I cant belive it wont work the body style and motor are the same. thanks for taking the time to get me a answer.

There's a reason why they changed the design. Usually it has to do with air being stuck in the system and they mount the holding tank up slightly higher to eliminate the issue. (sometimes only an inch makes a difference) This helps prevent blown head gaskets, which are common, mostly due to air pockets and lack of proper coolant circulation.

Whichever way you go just make sure to get the entire system (all of the pieces) from that year so it will work properly. A "mix-n-match" is asking for trouble.

IOW, the radiator and all of it's connecting parts, tanks, caps, brackets, hardware, molded hoses, etc.

RE: 2000 chevy malbiu radiator replacement
I agree with Rupe. It isn't like the "Old days" where you could just ram something in there and make it work. If you try that now to save a few bucks it will usually cost you many. I hope that you can find what it takes to make it work without costing a fortune.
Can't you just take the radiator back and show them that it's the wrong one?

Please let us know how things work out.

RE: 2000 chevy malbiu radiator replacement
Funny, I was just going to suggest that because it's probably under $200 and you are getting in way over your head already with something that's old and may cost near $200 by the time you retrofit everything.

It should be fairly straight forward to slip in the new one. Just pay attention to all of the connections being leak free. You may also want to flush the system while it's empty and only refill with water till you are sure the problem is solved. (no leaks or other issues) If all is well after several days then drain it and refill with antifreeze. Rule of thumb would be about a quart of coolant for each cylinder and the rest water. Top off the side tank with the rest if it all doesn't fit, otherwise fill that with a 50/50 mix.

BTW, if you have any issues with an air pocket in the system (common and causes over heating) try filling it with the top heater hose disconnected. Once something comes out of the heater the air pocket should be gone so reconnect the hose and finish filling. If that's a V-6 engine there may be a bleeder by the t-stat on top of the engine to do the same thing... and much easier. Go for a ride and if all seems ok the only thing left to do is double check the level the next day. Sometimes it settles after the last of the air burps out.

Let us know how you make out.
