hi chances are that it wont be a fuse but your coolant temprarure sensor swith hope this helps ?
If it is a clutch fan, it will only spin when the engine gets hot. You should be able to spin it with your hand but not freely like a household fan. If it is an electric fan, it won't come on until the engine is HOT. Or sometimes with the A/C. You can check with a test light to see if you have electricity to and through the thermal switch on the radiator. (When Hot) You can also supply 12V manually to the fan to see if it is good. I blew a fan, in the process the fuse blew too. Check the fuse box in the engine..
Pressure test system to observe leak
be careful while radiator cap is off!! remove radiator cap, start engine, watch for flow of water as the engine warms. temp gauge is a goog indicator.
If you suspect a problem, radiator shops can run a "flow test" after you remove the radiator and take it to them. If you don't want to remove and replace the radiator, they'll also do that part for you.
Try at the rear section of the radiator approx. 1/3 from the top or in the thermostat housing at the engine end of the upper radiator hose You can bypass to test fan motor operation
Remove The Radiator And Have A Radiator Shop Test, And Flush It.
Headgasket or head failure.
There is usually a noticeable aroma of anti-freeze coming from the exhaust, or bubbling in the radiator with the engine running. Also, there is sometimes oil in the radiator or anti-freeze in the oil. A compression test usually tells the story.
with the engine cold, remove the radiator cap ( the one that states do not open hot). is there coolant in it? if there is then start the engine and look for any large "burps" inside the radiator, rev the engine to 2000 rpm if the gasket is "blown" between cylinders and not to the water jacket a compression test will be needed
if your engine is running hot and its not your radiator you probably need to burp it to get the air out from the hoses and radiator, that should take care of the overheating problem, if it doesnt pressure test your hoses and raiator you might have a collant leak creating hot spots
With a radiator cap pressure tester. The tool usually comes along with a cooling system pressure test kit.
because one of the head gasket is blow, or crack you have to replace both gasket and compression test the heads
