Leaking antifreeze and it's not a pipe or the water pump
I noticed a large pool of antifreeze under my truck and it was leaking in a steady stream after i had let it sit for about a hour and a half. My truck is either a 1984-1989, i can't remember, Ford F-150 with a 351. My father thinks that it may be my freeze plug but we haven't taken the time to look at it. what other things could it possibly be? And if it is my freeze plugs will it require me to remove my motor?thanks for your help.
I have 1998 Dodge Caravan 3.0- antifreeze suddenly started pouring out from R side ( as you are standing looking under hood) Had new rubber gasket placed yesterday to a waterpipe but noticed leak is right below the pipe- forgive me, I am girl with little engine knowledge. I don't think it's the waterpump because it's on the other side. Have been trying to find engine cutaway diagram to see if I could find source of leak. Van has not overheated, yet, but as soon as water or antifreeze is added, it comes back out in steady stream.

Re: leaking antifreeze and it's not a pipe or the water...
May require vehicle on hoist or at least on ramps, and a flashlight/troublelight to see exactly where its coming from. Could be just a frost plug, but until you can pinpoint the spot, don't drive it, or run it for that matter & cost yourself more money.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Yes most likely it is. Theres a small hole on most water pumps when they start failing antifreeze will begin to leak out this hole. when the pump is moving faster the fluid doesn't have a chance to leak.
Obvious places include the hoses where they are clamped, the water pump gasket, and any fittings on the radiator, including the cap. Sometimes leaks only occur under pressure, so check while the engine is at operating temp and look for small streams pissing out from some of these places. Other leaks only occur when the engine is cold, in which case you generally find antifreeze on the ground. If antifreeze is dried up you can often still spot residue.
If all of that fails, it is also possible that you are leaking antifreeze into the engine via a leaking head gasket or other means. You would notice either puffy white smoke billowing from the exhaust if it is leaking into the cylinders, or you would notice a milky white residue in the oil if it is leaking into there.
you could have a expansion plug on the left side of the engine block leaking antifreeze,if your blazer is a 4x4 remove the skid plate under the front bumper and you should be able to see where its leaking from,a water pump will be a steady drip while its running usually but a expansion plug will pour out very fast
First, No your truck engine shouldn't need to come out if it is a frost plug. May be hard to get at but most times patience & the right tool will pop that bad one out for you if thats what it is. Do yourself a favor though, unless its the hole with a block heater in it, just by a rubber plug (similar to a thermos plug) designed to replace the metal frost plug. take your old plug with you for correct sizing. It's just a round plug with a nut in the center that you tighten once you've put it in the hole, and it expands & seals. Just remember you want it tight but not so tight that you snap the nut. Clean hole good prior to install. Will save you lots of time and aggravation. If it is your block heater, just buy another the same, they are pretty easy too.
Now to the Caravan, click on link below and scroll down to figure # 2 and click on the picture, that is your engine. Where about do you see leak from (area) Maybe below # 9? http://www.autozone.com/shopping/repairGuide.htm?pageId=0900c1528003c50f
Freeze plugs are usually on the side of engine block. If the freeze plugs leaking, it is a simple job to replace them without removing the engine. You should get under the truck to locate the source of leaking antifreeze.
freeze plugs checked they are fine all 3 of them. and nope the air conditioner isnt running. example: if i start it and let it idle it will leak visibaly but not a steady stream. after the motor starts to heat up the stream gets bigger and bigger but no gushing. oh and i forgot to mention the water is just water not other fluids in it. not to sound stupid but im not sure about which of the hoses are heater and radiator but we checked them all. there is a plate covering the face of the big end of the transmission and a pipe coming out of it and looks as if it is going into the motor. its leaking at the plate and entrance of the plate is what it seems like.
