Issues overheating

[rtvickers]

I have a 04 Cobra. I replaced the T stat last November. This morning it has been overheating. The is warmed up. I just went out and started it. The temp was normal and fan is on. I turn on the ac and its cold and the fan stays on. The ac gets hot and the car gets hot but the fan stays on. Not sure if the ac has anything to do with it or not. I will do it again after it cools down and wont turn on the ac. But could my T stat be bad already? Can these terminators run without a T stat? Thanks for reading.

Did you burp the air out of the crossover tee? Take the plug out of the crossover and stick a funnel into it. Let it run for a bit and add fluid in the tee.

The Tstat was done at a Ford dealership last November. Im assuming they burped it. Ive had no issues til this morning.

K so I changed the Tstat. Filled up the tank. Let run and about 20 min into it started to get hot again. So I took out the burp or bleeder plug. And very very hot steam came out for awhile. I finally got my funnel in there and it melted it. So I just poured from the jug. It worked for a minute but then it started spitting antifreeze everywhere. What did I do wrong?

Did you check for an obstruction on the inlet side of the radiator in the grill area? Double check. Then triple check.

Have you verified flow of coolant? Squeeze the return side hose to the radiator and see if you feel flow once the car reaches 180 degrees (or160 deg based on T-stat installed). If no flow then you may likely have a bad water pump or an air bubble somewhere restricting flow.

Have you removed the T-stat to see if the car stops overheating with the t-stat out? The t-stat may have failed premature. Things do happen.

Good luck.

Im going to try and refill the system and burp it correctly and see what happens. I hope its not a water pump. That looks like a big job. It ran for about 30 mins the other day before it got hot. I dont know, well see.

I refilled and burped the system today. What a time consuming process. Anyway, I let it run for till it got up to normal temp. I dont have a temp gauge yet so I let it get up to the middle of the gauge where it normally is. Then I took it for a ride. I went through town then got on the highway and then back through town. With alot of 3k rpms and revs. Seems to be holding a normal temp. Hopefully its fixed. I think it was just an air bubble. But I did change the Tstat. I will test the old one this week and see if it is bad. Thank God so far its not the water pump. Its just been one of those weekends for me. Anyways, tomorrow I will take it for a longer ride and see what happens. Thanks for all of your advice.

Good to hear. Mine goes on he trailor to go to the speed shop Saturday morning. Done all the checks I can do locally. Hopefully its something simple but I suspiscion based on findings and research that I may have to rebuild the Supercharger. Still cheaper than a short block or long block though. That all appears in good working order.

Glad to hear it seams to be running better. Air in a water system is a funny thing. You would think the pump would push it through but it doesn't always work.that way.

Brenspeed - Certified Speedlab Saleen dealer. Believe the SC (Saleen twin screw) may have let loose. Not sure, but while very, very uncommon, the gear box seals have been known to develop a very slow leak over time which allows the oil (self lubed) to escape without notice on the early model series VI. Was told there was no need to worry about gear oil change for 50K per Saleen. A few of the earlier VI series Saleen twin screws apparently were built with an inferior gasket material that is a green/blue in color. The newer gaskets are made of a red material and are holding up fine. I may have just gotten one of the very last ones on the market (my luck) because the gasket material on mine sure isn't red by the looks. Will know more when they pull the snout to inspect the gear drive. Way cheaper than a short block or head rebuild though and is likely still under warranty. My compression checks and visual valve train inspection revealed nothing out of the ordinary. No CEL lights. Good excuse to slide a set of LT's on the car while up there as well. :)

These guys have been great to deal with and the trip is worth it. They really take good care of their clients and stand behind their work and warranty. They have not blown me off one time during this process and have answered every question quickly. I have learned quite a bit from the experience which is a good thing. Have a great week. After all that is what it is all about.

Sounds like you have the same luck I do. Something that has a 1% chance of happening, happens to me alot. I agree, alot cheaper than a short block or head rebuild. I have a whipple and I called them when I bought the car and asked them about service on the SC. They told me that they get serived. They last 100k miles. And then replace them. That just dont sound right to me. But anyway, have a safe trip and good luck. Let me know how it works out.
