99 I30 replace radiator

[muthiahmerchant]

I was trying to replace my radiator. removed bunch of screws on the top but could not remove the electrical connector. Any tips on how to remove the 2 electrical connectors is greatly appreciated.

Thanks

On top of the connector, away from the radiator, there is a release tab. Depress/squeeze it and then pull out the plug.

Any reason why you are replacing the radiator? In our 99 I30 there was a radiator leak so I used Bar's Leak Pelletized Radiator Leak Sealer. Then I realized that there's a 4-inch crack just below the filler neck. I used JB Weld Stik to seal the leak and so far, repair looks good. Of course this is only temporary while I weigh my options - OEM radiator from IoS is @ $425 while aftermarket is @ $125. I normally go for OEM part but this time may go for OEM-compatible.

After I drive for a while the top of the radiator and surrounding parts are spashed with coolant. The mechanic said I should replace the radiator. I got aftermarket radiator from advanceautoparts. But i will try the sealer before replacing the radiator. my car has 180000 miles. But in any case, how to disconnect the wiring harness. its just so tight.

If coolant is splashed over the the area, it's possible that you have the same crack like mine, just below the radiator filler neck. As for the connector, as I have said, squeeze the tab on the upper part of the plug to remove it.
