Maybe it was cause it was cold (40 - 50 degrees out) but I changed the thermostat yesterday, and filled the whole system with water, I mean pulling hoses and dumping gallons of water in, even directly into the engine.

also bought a new radiator cap and the thermostat is a autozone generic.


also what is this?


it has broken into many pieces. and a couple times when overheated it was shot out of the hole (the center portion of this thing) with much steam coming out.

I want to get coolant in the system but not until I get this issue fixed so I am not throwing money in the trash.

either way I had heat out the heater before today, and now NOTHING my 2 hour commute was freezing. I stopped a couple times with the engine running and fed it more water.

I dont suppose my water pump went out? revving the engine I can see water fluctuating in the overflow.

I am really suprised with how long it has overheated to red and its still running great, I really dont want to have to push it anymore, specially since I just overheated and ruined my Previa van over the weekend as well, iron block and alum head and now that wont start at all I DONT WANT THAT TO HAPPEN TO MY SC400, help?

I think you just answered your own question.

That "million pieces plastic thing" is the temperature reader, somebody correct me if I'm wrong. Find a JY SC and grab that mechinism and swap it out for yours.

my gauge is registering a temperature though.

coolant level sensor. little light above the temp gauge on dash that looks like a prison window.

Did you check the oil to see if it is a coffee colored. If that is the case it may be a headgasket. Try the simple things first like new radiator cap, inspect radiator for cracks/leaks, you may also have air in the system. Good luck

mine was coffee colored! what does it mean, i thought it was just dirty? does a new cap really help?

PseudoK

Yea mine would be a different color than that because of royal purple lol.


but yea already new radiator cap and thermostat.


but the thing is the heat was working yesterday before I changed the thermostat.

drove all the way to work today (80 miles) with no issue of overheating, just frozen from the lack of heat.

If your oil looks like a milkshake....which would indicate you have coolant in your oil.

A new cap is only necessary if your radiator is not holding pressure

Guessing you don't know how to fill a car with water?

SC4ME

yea it does lol, not saying that i would drink it, so how do i fix this problem? thanks!

SC4ME

is royal purple even good? i never tried it.

PseudoK

SC lesson number 458: that 17MM bolt on top of the thermostat housing must be for burping the system of air, because as SOON as I opened that and revved the engine heat started coming out of my heater.


now I believe the car shouldnt overheat anymore, I have only been concerned about the lack of heat from the heater. heres hopen.
