Koyo Radiator Failure
I recently heard the low coolant buzzer going off so I checked to see what was causing it. It seems to be leaking by the threads on the coolant level sensor.
From what I can tell, there seems to be a plastic insert for the threads that some how broke and will not allow me to unscrew the coolant sensor.
My question is, has anyone heard of this or had it happen to them?
If so, HELP!! Does anyone know where they sell replacement parts?

koyo radiators are 100% pure aluminum they dont use a plastic threads for the level sensor. You sure its a koyo? Now the stock sender piece has plactic threads on it which i think its a shitty design, that could be your stripped peice.

Were you having trouble with the car overheating? If not, your efficiency is basically a waste (lower radiator temps do not make the engine run better).
Because the thermostat controls the engine temperature, as long as the radiator is adequate to keep the car from overheating, it is fully sufficient (a bigger radiator does not make a colder engine).
Actually, the under-engine pan and the skirts coming down from the hood latch make more difference for overheating than the radiator, as they channel air through the radiator at highway speeds.

. I didn't buy it, came with the car. There appears to be a white nylon ring under the level sensor though, and it turns with the level sensor. The sensor neither tightens nor loosens.
If this piece were stripped don't you think the sensor would come out?

i have heard good things about the stock radiator, and more good things about the stock fan/ shroud. I hear more about over heating with e-fans and aftermarket rads that the stock setup.
Post pics of the broken piece so we cans ee what your looking at, might be more clear then.

I guess we both may need to find parts.

I've got the same problem, but mine is much less severe... for now. I can tell coolant is escaping but I have yet to have to add any more (9 months and counting).

I wish I was driving!
I like to install a sacrificial zinc anode with a new aluminum radiator or a new engine, as well as run a new block ground. The $10 anode is cheap insurance for your cooling system.
