overheating FAST?

[PewterLS]

I mean this car was sitting for a couple of hours, took of in it and drove a 3/4 of a mile (at 45mph) and the car was overheating (guages went off and car went to safe mode). Antifreeze boiling out and I also noticed that the hyd, fluid on the driverside reservior looked as if it ran over also.

I am doing a compression check to make sure that it wasnt a head gasket, but I dont know what these cars will do with all the nice gadgets that these cars have.

Any ideas?

I was thinking maybe a thermostate, but would it heat up that fast?

IS there anything that I should look for while I am under the hood to make sure that I have everything covered?


Also, how does the hydraulic fan work? (I am assuming that is all that runs off the pump?) maybe powersteering also?

The plastic cooling pieces are cracked to hell.

Check the degas bottle.

+1 just did mine and fixed my issue

I would start with the thermostat. It is cheap, easy to replace and more than likely the issue

What is the degas bottle ands what plastic pieces are we talking about? I read in the tech section about the degas valve but nothing for a bottle?

Ran a compression check and it seems like all cylinders are good!(all around 150) That is really good news.

With these questions I suggest you take it in to your mechanic. The Degas bottle system has been used for over 30 years. It is what the overflow reservoir evolved into.

Lol thanks.
I assumed that was it but was unsure. I rather know details than make assumption when asking for advise or input from others
I mess with cars as a hobby, but rather learn vs paying someone else turning the same wrench as I can

Its the plastic bottle for coolant on the driverside, mine was sparying it all over the place due to a pinhole crack that started to leak when the pressure and heat got up.

got mine off amazon for $64

heres the link for the replacement, wasn't to hard to do

Roger. There's a wealth of information in the tech articles.

Well, looks to be the degas tank.....

There is a pretty big crack down the side. It does suspense me that I have not smelled or seen antifreeze anywhere. The car is parked i'n the garage every night also and never s puddle or drip.

I went ahead and pulled the thermostat and replaced it since I was already i'n there

For those who have done this, I think that the hardest part of all this is going to be hooking up the bottom hose to the degas tank lol

I hope you bleed the cooling system right after doing that, or its going to continue to overheat. and yes, the bottom hose is the hardest part just because the tight area

Actually if you take the driver side wheel and inner wheel well off, they have an access hole to get to the bottom of the degas bottle. Makes it really easy to get it on and off.

Check Hydraulic Cooling Fan Speed.. If its running slow and not actuating then its the Hydraulic pump actuator. About 150$ fix

I was going to do a search today and see what is the best way to check the fans and make sure that they are working correctly.

I do know that the driver side can was still normal (little low) but the passenger side one looked as if it overflowed.

I did notice that there was some trash between the condensor and the radiator, nothing bad, but I am going to pull it out or see if I can get some cleaner down there and rinse it out. I know that it didnt cause the problem, but at least if this doesnt fix it when it is back together, I can eliminate one more problem

There's only one fan. The driver's side reservoir is for the power steering fluid and the passenger side is the hydraulic fan. With the A/C on the fan should kick into high. From what I've read here the actuator seems to be the culprit.

I had the same problem, and I took the wheel well off. But I still didn't have enough room. That's when I had my dad bend the metal around the access hole back a little. Doing so gave me plenty of room to put the hose on AND tighten the hose clamp!

He was talking about the Reservoirs

Passenger side is Hydro fluid for fan. Drivers is Power steering

You will know if its working right.. it Spins pretty fast and youll beable to hear it with the hood closed. And your fluid needs to be a DARK red. Not milky pinkish.

That means you have water in it and needs to be completly flushed and replaced. If the actuator is your problem check out my Write up on how to replace it.
