something "fell off" *update page 2*

[packrat427]

^^ YES , I can vouch for that :lol: :lol:

Something fell off and now it overheats quickly ..

I am guessing the pulley center broke out , form the belt being too tight , then the belt flew off , and the pulley is hanging on by 1 bolt .

Just a guess

Let us know please .

hes going to drop it off on friday morning now, but i'll be in TX till Sunday or so. So i won't be able to check it out foe a few days.
btw, about the boiling, the car was not mine at the time so i wasn't looking to closely at everything. i only saw in with the hood open for a few minutes.

I think we need some more clarity.....
First coolant should never boil! Flowing into the over flow does not mean it's boiling. Any normal car...when normally heated up...will experience expamsion of the coolant and flow into the overflow. This is required because all heated fluids expand and will cause an increase in pressure and before something blows the radiator cap relieves pressure by dumping fluid into the overflow tank. This is why it is so critical to routinely change the radiato cap which controls coolant system pressure.

What's really important to know....how fast doe the engine get to the over heat condition? Sspecifically at idle and what's the ambient temp at this time.

Never drive an overheated car............................................... ...........................................period

Change the collant........................................... .................................................. ...............period

Buy a hydrometer....they hang in the store where they sell coolant...they measure the freezing and boiling point of the coolant....I bought mine 25 yrs ago for maybe $2 or $3.

If something "fell off" the car and it overheats. I would check the belt and pulley's. Packrat had the pulley fall off his car before.

I could not agree more. Coolant should not boil in the system, but how often, especially when loss happens, do people replace with just water? That can explain why it can boil, as well as just bubble, inside the overflow.Once it escapes the system, from the pressure cap, as you stated, Joe, the water can then boil. A cooling system does not usually contain pure antifreeze, and even it can boil, just at a much higher temp!

Possible scenario;
The guy you bought it from had the pulley hanging by one bolt, overheats. Replaces fluid with water, drives and overheats some more. By now, the aluminum head MAY have warped, thus causing boiling or bubbling in the overflow.

Just one possibility, and yeah, I really want to know, it has gotten my curiosity juices just a boiling

Didn't mean to cause a fuss here, was just trying to add to the list of things to check for

[cubstiva1]

i hope that there is not major permanent damage, i'd really like to get it running. i have an 93 festy engine that i could replace it with if its really jacked up.

scitzz1....I was not in disagreemnet with your post...I was only trying to explain how a normally functioning well maintained coolant system works.
Don't forget that as the pressure increases...so does the boiling point. If you put pure water into a a good antifreeze hydrometer, the boiling point will be higher than 212° because the hydrometer is calibrated for 1bar (14.7PSIG)

I have a question....if the water pump pulley failed...shouldn't also the alternator and the charging circuit?

[scitzz]

You know, after the first time you do one, the festy head change just isn't that hard. Even the first time should be relatively easy with help from a haynes manual, and this gr8 site! I can tell you, you would need either a 12 or 13mm, thin wall, 12 point socket for the head bolts, I think 12mm, but it has been a while......

I don't want to make ya think you need to do the job, just wanting to let ya know it is a possibility...

Hopefully it is something a whole lot easier though, and still, a good find!

[worfdog]

maybe the fan belt or pulley for the fan belt?

Mine has electric fan, don't all the festies? I mean, it is a front wheel drive

I know,I'm from the old school. When i was growing up about the only front wheel drive cars were cadillac el dorados and olds toronados and they had fans driven by a belt.I'm 54 years old and most people my age around here still call them fan belts although you are correct in calling it a water pump and alternator belt, Heck i still call alternators, generators.

Thanks, i stand corrected.

^^thats what I was thinking when I mentioned the belt.

"In my own personal experience, I have never seen a faulty head gasket leak from the mating surface between the block and the cylinder head, and boy, do I get a lot of blown head gaskets! Common symptoms of a faulty head gasket are;oil in the water, water in the oil, steam from the exhaust, as well as water dripping from the exhaust,overheating, and bubbling coolant overflow. The best way to be sure of the diagnosis is a compression test, IMO. Oftentimes, pulling the plugs and checking their condition will be a dead giveaway as well. " ..... scitzz1....I agree to a point....I have personally had 3 blown head gaskets....2 were outward as I mentioned in my previous post....one was inward like you said.

He will know more once he gets it home......look at the coolant and see what color it is first off....if it is green or clear water then I doubt it is an inward blow....time will tell

Wow, see, now I feel like a jerk, I didn't mean to come off the way I think I did, I must be frustrated, well, I know I am, I hate removing heater cores, and that is what I am doing on an escort today. I have a bad back, and all the contortion makes it hurt. I have to work for like 10 mins, stop for 20, and so forth. Guess it is making me cranky, and I do apologize.

Geneva, I have heard of them leaking outward, I was just saying that it seems rare to me.....since I haven't seen one do that.

worfdog, I was trying to play around, I am not as old as you, but at 36, I knew what you meant.....

Joe, you are 100% correct, it does increase with pressure, and yeah, wouldn't the charge light be on? hmmm, like genevadirt said, he (and we) is/are gonna just have to wait and see....

I don't feel combative, but since I think I came off that way, once again, I really apologize.....

[worfdog]

No problem, I do need to watch how i state things.The way i say somethings could be confusing to some. You just reminded me.

I know how it is when frustration set in. It happens to me much to often.

ahhhh I think it's time for a group hug. *warm fuzzy feeling*

:lol:

[cubstiva1]

he said the belts fine, i asked this morning

[scitzz]

ahhhh I think it's time for a group hug. *warm fuzzy feeling*

:lol:

awwwwwwwww ops:

[geezerstiva]

fall off??? how on earth did that happen? i'm assuming that you mean the water pump pulley right?

[cubstiva1]

i finally got a change to work on the car. i have no idea whats going on. when ever the engine is running or even cranking over, the cooling system builds a bunch of pressure and blows out the cap and into the overflow. i changed the head gasket today, with hopes that was it. it might be a bad head, ( i was in a rush and was wishfully thinking, so i didn't get it checked out). i also removed the thermostat and still the same pressure. not sure what to do now, might wait a week and see what i can figure out after sleeping on it.

Ps would i be able to replace the head on this carbed 89, with the head off a efi 93? just the head, and keep it carbed?
