Default 91+ closed radiator in an 89 renix?

How could I convert my 89 open cooling system to a 91+ closed system? Also if I did this do I retain the mech fan and the e fan?

Put the later radiator in with a coolant reservoir to match.

What's wrong with your system now?

I think my rad is clogged up and it doesn't seem to be taking water from the reservoir

Just so you know, you have the closed cooling system and will be converting to the open cooling system. I just did this last year on my '90, piece of cake. Buy all your parts for a '91 or newer. I kept my old resevoir, only because I couldn't figure out how to mount the newer version. I connected a line from the bottom the the tank to the radiator fill neck connection, plugged the top line connection and drilled a vent hole through the cap. I even installed a newer style heater control valve. It's a good idea to replace your tstat, water pump and belt while you have the radiator out. Good luck!

I'll agree with all of that, except it's best to save the money and frustration by eliminating that heater valve.

O ok i thought cooling systems with the rad having a cap was a closed system may be wrong not a mechanic but yeah I was planning on swapping all new cooling components in whether I keep it open or closed but I'd really like to switch it just for simplicity.

I just did this swap, watched the same 3 bleepin jeep videos, but I just ran a toggle switch to my electric fan and ran the hoses without a heater valve but used the connecters to get the flow correct like in the video, works great, post up when you got it done
