Flushed my coolant - Now have problem

[Miles]

Unscrew rad cap and start car. Let it reach norm operating temp. Rev car. Watch coolant bubble out of reservoir. When it doesnt burp anymore, replace cap. Enjoy.

The problem is called an air lock. Keep bleeding the system. It is kind of like when you go into a new house & turn on the shower for the first time. It spits & sputters all the air out before you get a steady stream. In an enclosed system like your coolant system, the air just can't find its way out.

My coolant light is always on, has been since I bought the car. The guy just had the coolant flushed before I bought it, so it may be too much water like you guys are saying. It doesnt really bother me, its full of coolant and it doesnt run hot, but I may try and burp it or something.

Thats what I did after my headswap, just leave the cap off, start the car, wait for the light to come on, then have someone start putting in the coolant till the light goes off, repeat for a couple of mins and you are filled up and ready to go. Good luck.

I had another question though. Is it possible to put too much fluid in the expansion tank? The last time I added fluid, I filled it up all the way to the top of the neck where the cap screws on. Could this cause damage? Would excess fluid simply spill out of the tank?

The excess would usually just drain from the overflow

I haven't looked at my 03, but my Moms 94 had the level sensor located on the end of the shaft of the overflow cap.

Clean the two exposed contacts with a wire brush. The contacts allow a small charge to pass from one throught the fluid to the other. If they are corrded, no signal is received and you get a low level light.

the newer cars have a degas bottle and not a overflow tank, there is no sensor on a wand like the cap on the 1994 mustang. the sensor is built into the degas bottle ( where you put the coolant)

I am almost 100 percent sure the sensor is not sold seperatly, we sell the whole degas bottle when this happens

if there's air in the system, the heat won't work ... i went thru this nightmare when i replaced my rad assembly... what i did was basically just squeeze the hose for a good 30 seconds, that sucked the water thru the system and pushes the air out (the rad cap was off) and after i did that, it worked fine.

but if ur heat works, there isnt any air stuck in there.
