You overheated cause you had no coolant. Its not because of your thermostat or water pump. And that is your coolant flange, they warp. But never heard of them squirting coolant. Are any of your hoses broken?

I think I have big issues......I connected all the hoses back up. poured coolant in the system and it started leaking right away (without the engine running). It looked like it was coming from the flange that is attached to the block. I took a pic.....brb


Here it is. If you really look hard, you can see the stream of coolant at the bottom bolt. Now what??? Can I just change that flange? Get a new gasket? or is my block done? This is really stressing me out!!

I think i found the issue. I took the flange off and found that the gasket is pretty f'd up. I will order a gasket from the dealer tomorrow. Do you think I should change the whole flange/housing?








Thanks for your help and quick replies MCROW!!!!

I replaced the flange and filled the system with coolant. Everything held and the system had no leaks.

Tried to start the car and nothing. It wants to start but just won't kick over. Battery is at 12.59v. I cleaned the air filter. Took the hose off the MAF and found a small amount of OIL!!!!! WTF.....

Kept going up the line and cleaned everything. Put it back together and it still won't turn over!!!!

I'm at a loss.....

Do a quick checkover of your engine and make sure everything is plugged in. Especially your engine coolant sensor.

Hi

My car is overheating and i have no idea where to even start. on the hud the temperature needle stays on 90, but the radiator doesn't turn on and the temperature warning light is constantly flashing. I've checked the fuses and none of them are blown, under the hood the water coolant thing is really hot and when i open it boiling water literally sprays out as though its under a lot of pressure, and then its empty.

I have no idea what's going on (clearly) or where to start, but im keen to learn for future issues.. can anyone help?

If your gauge says its running at 90 degrees then its not overheating. That flashing light on your dash means that your coolant is too low. Top it up and see what happens. And yes it will always spray out on you when its hot, its a pressurized system.

Normal operating temperature should be around 90C not 100 or 110C.

Hi,

I've got a Jetta 3 CSX 1997 model, that also got a problem on the cooling system.
1. Two months ago I replaced the Front flange that houses the ECT sensor. That stopped the water leak.
2. Today the temp gauge stood on zero on a 30km drive at highway speeds. When I checked the system, I found it full of coolant, but when testing the ECT sensor I got readings between 29 kOhm and 10 kOhm when heated up to about 80 deg C.
3. According to the specs it must be approx 550Ohm at 85 Deg C. I put a resister of 550 Ohm on the plug and the needle stay on zero.
4. Another thing I noticed is the erratic iddling and rev counter not always indicating. With that flashing oil pressure light. Tested the pressure at Filter and head and all okay. Someone told me the rev counter is the culprit.

Anyone that can help please do so.

Awaiting your replies.

Actually that's what mine did it was squirting from the bottom where it was warped.
