[QUOTE="okiebryan, post: 2050865, member: 24457"] You can go years without fixing an exhaust manifold leak, so long as you aren't getting gassed out in the passenger compartment. The random shutting down is consistent with an ignition coil problem. Especially knowing what I know about the 4.0L V6. If the tranny leak is from the pan, that's a cheap fix. The coolant leak will have to be fixed, but you have to pinpoint exactly where it is leaking from. You need to wash thoroughly under the hood, then pressurize the FULL cooling system (with no air trapped inside) with one of these: [IMG]https://www.okshooters.com/data/MetaMirrorCache/images.carparts.com_design_assets_classroom_images_pressuretester.jpg[/IMG] Then you will find exactly where it's leaking. Replace whatever is leaking. Radiators are very easy to replace in a 2007 Explorer. Aftermarket radiators are good to go. [/QUOTE]
