After 20 minutes, your motor usually comes up to temperature, so that's when the thermostat will open, and start circulating coolant through the radiator. (before that it is just recirculating in the motor). It also takes that long to build up heat pressure, so a leak appearing from the radiator at that point does make sense.

Removing and replacing a radiator is a fairly simple disconnect, reconnect job.
But a new radiator can be somewhat expensive. Some are made from aluminum, some copper (being that yours is a 2001, it's probably aluminum).
So the first step would be pricing out a replacement.

To actually R&R it, let the engine cool, drain the coolant, and dispose of properly, disconnect the hoses, if it's an automatic transmission, disconnect the cooler lines, and plug them with small rubber plugs, and then locate and remove the radiator hold down (it can either be the top plate, or just a couple of simple clamps, usually on the top only. Then lift out and remove the old radiator (it just sets down in the bottom locator) installation is the opposite. Set it in, connect the lines, refill with fresh coolant.

I would not try repairing the old radiator on your own. It can almost be considered an art to clean and re-solder leaks on them. You would then also need a tank and a pressurizer to test it after.

However, you can take your radiator to a radiator shop, and have them repair it for you. Depending in the leak, this can save a substantial amount of money.

A job like this should take less then an hour if you have a new part in-hand, longer if you decide to take it in to be repaired.

i would look around the fuel injector themself be sure to use a flashlight for safety and go to an auto parts store and replace the o-ring or rings on the ones that is needed.

This might be a result of an oxygen sensor. If you take the vehicle to a store like autozone, they will attach a diagnostic sensor to your vehicle at no charge, and then reset the unit, and be able to tell you what is going on. This is at no charge, so there is nothing to lose. I hope this helps.

sounds like the clutch field on or bearing on the front of the compressor went bad take a closer look at the pulley on the comp. and see if there is any debris or melted plastic coming out behind the pulley,if so the clutch,field and bearing should be replaced,hope this helps
