Hi is there anyway I can clean gunk out of my radiator. I recently had it flushed.its causing me to have loss of a lot of antifreeze/water n my radiator. Its shooting gunk through my thermostat area

SOURCE: Engine overheating at high rpms

check the casting on your replacement water pump..4.0l engines require a reverse rotating water pump..may be causing your problem.

SOURCE: loss of coolant (leak) in the radiator. causing overheating

They can be a real challenge to find, especially if the leak is buried somewhere that you really can't see. Then after driving around, the fan and wind spread the coolant all over , making it even more difficult to locate the source. 1st try 'stop leak' which can be purchased at parts stores, you might get lucky and it will fix the problem. Sounds like a good idea to replace the radiator if it's rusty. You could have a leak at the head gasket, or even a freeze out plug on the block. A couple of suggestions to help locate it: pick up a small mirror at a parts store, the kind that folds and extends. Get the car up in the air so you have plenty of room underneath to move around, and securely supported so the car won't fall on you. Clean off any drips or visible coolant. Start the car and crawl around with your mirror and a good flashlight, and wait for evidence of coolant to appear. It's a matter of patience and poking around to find it. Good luck.

Testimonial: "great advice!"

The best way is to overhaul your radiator so all the dirt
can be taken out. But, for the meantime, open the drain,
and let the water flow until most of the gunks are gone.

You have an air bubble at the top of the engine.
The antifreeze spewing out of the overflow happens due to your perfectly functional radiator cap
passing the overheated coolant/air mixture out of the system into the reservior (in an attempt
to relieve overpressurization of the cooling system)
The sudden nature of your overheating comes from the boiling of the inadequate amount of
coolant/antifreeze in your engine, since it cant properly cool the engine, so it boils (overheats quickly), and pressure rises immediately within the cooling system.
The Fix is free: locate and open the (air) bleeder port at the top of the engine, and add the usual
50% coolant/50% water mixture to the radiator until the radiator is full to the level indicated in
your owner's manual (or the "Full" line). Then close the bleeder port and replace the rad (radiator)
cap.
The air bleeder port is normally located near the thermostat, and should be opened each time
that coolant is added to the radiator. The air bleeder port need not be opened when adding
50/50 coolant to the reservior, since the rad cap is going to be closed while adding coolant
to this part of the cooling system.
Warning: driving beyond the point where your engine temperature gauge indicates overheating will
destroy the car's engine - it'll seize up due to overheating, and the only fix for a seized/burned-up
engine is replacement (of the engine). Seizing an engine is really easy with an air bubble in the
top of the engine - you could easily burn up/warp the head, necessitating replacement of the head
and head gasket.
