Overheating, with new parts!

A desperate girl again guys. My car overheated 3 weeks ago. my brother replaced the water pump, thermostat & the fan switch, still gurgles out of the reservoir. the electric fan works because it turns on when you use the AC. he also jumped it at the fan switch and put a new switch just to make sure. now the temperature remains 1/2 way on my intrument gauge but the reservoir boils and gurgles, please help!.
thanks.

Last time I saw that it was a blown head gasket. Is there any black sooty stuff showing up in the reservoir? Along with your other overheat problems its starting to add up.

No black sooty stuff on the reservoir just 50/50 coolant and water.

hmmm do you sit in alot of stop and go traffic? if so, does your fan run when your idleing? take a flip flop or something like a newspaper rolled up and see if you cant stop the fan with it... your fan may have a bad clutch in it and not be putting out the kind of cooling it needs...

Ha! That sounds familiar! Flip flops... Every mechanic should have a pair!

How many miles do you have on your car? Have you ever had a coolant system flush? If you have a lot of miles on the car, it is possible that you have a blockage in your radiator. The failed cooling fan clutch is also a strong possibility. If you aren't getting any milky residue or black grit in your coolant resivior, I would lean towards either the fan or the blockage in the radiator. When the car is cooled down, open the radiator cap and see if you have a lot of white build up on the inside of the radiator. If you do, you seriously need a good system flush.

Remember, always start with the simple stuff first as that is usually what goes wrong first... Also, if you have a bad radiator cap, your cooling system won't keep the correct pressure in the cooling system and cause it to over heat.

Good luck,

Getting a cooling flush and new thermostat, also the cooling fan is strong with the test (flip flop)

Let us know how this pans out. I am interested in knowing what the problem was... If I can think of anything else I will let you know.
