Replace raditor 2001 chrysler 300 M - 300M Chrysler Cars & Trucks

I found plenty of compatible radiators for around $100. Expect about 1.5 - 2 hours for the job plus you should also plan to replace the thermostat and all the coolant at the same time. So maybe $75 for the coolant and thermostat. Labor varies but a good independent shop I use charges $65/hr.

I included a link to a replacement radiator just to give you an idea of pricing. Chrysler Sebring Radiator

You must do the replacement from under the car.

Faulty water pump is the next thing I'd check.
Also backflush the cooling system if you haven't already.
Check to see if you have coolant in the oil. You may have a bad head gasket.

relay changed also? That relay will turn it on and off as well

This can be caused by a failed head gasket at a point that allows high temperature gases to escape into the coolant channels. Check your coolant for odors you would associate with exhaust fumes and check the color of the coolant mix to see if any contaminants are in it.
You might also do an inspection of the oil level dipstick to see if there is anything resembling Jergen's lotion on it; this can happen with a severely leaking head-gasket too. This kind of failure by itself ~just~ destroys the engine over time but doesn't affect the coolant temperature.

your tank os on the right side standing in front of your car,it's the bottle and your radiator is in front of the engine,it looks like a bunch of black finns.

you may have a water pump that is starting to fail. Look for the water pump that's driven by the fan belt. look at the housing of the water pump there is a relief hole that they drill in the casting and when the pump begins to fail it will drip out this hole. If that's where your leak is, it's time to change the pump.

try to disconect the bottom hose and drain it, the plug is located most of the times on the drivers side bottom corner of the radiratior.

Looking at the directions....for battery removal, it doesn't state removing the air filter cover but to do that, all you do is unclip the cover of the air cleaner....very simple.
