Do you have the right mix on the coolant you have in the engine? Could you have trapped air in the coolant system, did you have the heater system on when you were filling up with coolant. I assume you changed the radiator cap when you replaced radiator. I guess it could be caused by headgasket, are you loosing coolant, does oil look milky or oil in coolant. Belo link list a few things to look at but you have addressed most of them. Ford Ranger Overheating (repairpal.com)
Basically, remove and replace, drain coolant from radiator, locate t-stat housing, remove bolts, remove t-stat and replace with new,make sure the pellet end of t-stat goes in first, re install housing and new gasket or o ring, refill, burp air, and top off, put on the cap, That's about it.
Hello again Vicki, you can read my first post to you on type. Now for where and how. Put suitable container under radiator drain valve. Start to drain old antifreeze, you can also loosen radiator cap for faster drain, but make sure antifreeze doesn't start to spill all over your driveway or garage floor. When radiator and engine are mostly drained, I would recommend to change the thermostat. Follow the top radiator hose down to the engine. This is where you'll find the thermostat. Remove the attaching bolts and remove thermostat.If you wish to flush your engine,you can put water down the thermostat hole as well as the radiator cap hole, or you can do a fancy flush. Shut drain below, reinstall thermostat housing without thermostat, fill radiator with fancy flush cleaning solution and water replace radiator cap ,run for time stated on can of flush. Now you go back to where I began and start the draining again. Dispose off antifreeze correctly it is dangerous to animals if they ingest. Close drain,and fill engine with antifreeze thru thermostat housing, when almost to top install new thermostat and gasket. fill radiator almost to top, start engine, open inside heater and let engine warm to operating temperature. At this time the antifreeze level will drop, because thermostat will open, and you can fill some more .This should eliminate any possible air bubbles. Fill your coolant tank. I would like to know how you make out. GOOD LUCK.
well its bound to make a little mess but you should have a drain plug on the radiator at the bottom towards the engine side on one of the 2 tanks (sides of radiator ) unscrew drain plug and let drain into a pail or pan ( 2 gallon ) after it drains remove lower radiator hose. use a garden hose and fill radiator and let it flush for a little, hook lower radiator hose back, tighten drain plug and fill with a 50/50 mix new antifreeze,
No, the flush kit is mounted on the heater hose and you need to drain the system. Removing the lower radiator hose and termostat is the best method for flushing draining the coolant system.
From your description it sounds like your engine is overheating. Make sure you have enough coolant in the radiator and the coolant reseviour. Check your hoses, radiator, and waterpump for leaks. Have your thermostat replaced if it needs to be. If you can't get hot air from your vents when the engine is heated up it most likely means your water pump impeller is broke and it's not circulating coolant.
you need to flush the radiator out.
With the engine cold, remove coolant bottle cap to release pressure.
Drain engine coolant from drain plug on radiator.
With the drain plug removed disconnect the highest hose connected to a radiator.
use an hosepipe and put it in place of the disconnected radiator pipe.
turn on the water to the hose pipe and let it flush out any sludge accumulated in the radiator. after a few minutes turn off water supply, reconnect radiator hose and drain plug and refil using recommended coolant mix for your galaxy (purchased at most autofactors and garages).
Also check your thermostat as if this is faulty it would stop the flow of coolant running around your engine.
The upper radiator hose is connected between the upper radiator and the thermostat housing. Drain the coolant then remove the upper radiator hose from the thermostat housing, replace if necessary. Remove anything blocking access to the two bolts holding the housing to the engine such as the belt cover. Pay attention to the orientation of the thermostat so you install the new one correctly. If the housing is corroded or pitted you have have to replace it or suffer leaks. Push a rag into the engine opening now exposed and clean the contact surface well so it won't leak later. Installation is the reverse of the process.
Look into the inside of the radiator. If you can see the tubes that the coolant flows through and they have deposits around the ends then it has lost it's capacity for water flow. They way to correct this is to remove the radiator and send it down to a radiator shop and ask them to have it rodded and cored. They remove the tanks and run rods through the tubes and clean them of all deposits. This greatly improves the cooling capacity again. You probably have a severely contaminated system on your vehicle.
