The freeze plugs can be found on either side of the block. They may be hidden from view by the exhaust manifolds but can be seen from underneath.

Why water coolant leaking from water jacket


water jacket? You mean the engine block? Failed gasket, loose core plug, and hopefully, not a cracked block.

87 ford ranger coolant leak not from water pump replaced it today appears to be coming from right behind it


I can give you a couple of possible causes(1)freeze plugs in the block,there round & look like drink coasters,but are brass(2)intake manifold gasket can be leaking from the corners where water jackets are/also the head gasket both are on all four corners,I don't know what motor you have,but there are pipes that are called crossovers that run from the back off the timing cover to the heater core on the fire wall,sometimes on top of the manifold on one side & there will be a hose connected to it possible bad hose or corroded tube?

Car is overheating quite frequently


could be water pump. Check weep hole on water pump body to see if its dripping. if it is, then your pump seals are bad. Now, if coolant is leaking from engine, it could be from water jackets or engine drain plug. this all depends on where you're seeing coolant leaking from. Also, if it's not registering as hot, you might want to look at the coolant temperature sensor.

My 1991 honda accord runs hot its full of colliant and it pushes it out of the jug whats going on


Sounds to me like a blown head gasket. Compression leaking over into the water jacket and or leaking from combustion pressure leaking over into the water jacket pushed coolant out the overflow. This would be the better of another possible problem, water leaking into the oil! Water neither cools or lubricates the bearings which unfortunately live a short life. Check your oil. If it looks like Chicken Soup you may need a short block. I hope it is only your head gasket.

2000 mazda protege water leak under passenger side. A/C not used. Can't see any water in engine compartment or on firewall. Floor carpet is dry. Just drips from big bolts on frame under pass. side.


Possible the hot water line to the heater that has leaked from the water jacket or the connection at the heater pipe. You must be able to use a good observation lamp to look into this section so that the joint from where the leaks appears is located. Possible that the gland or the connector can be tightened to stop the leak.

You may have a head gasket in the throes of failing.
Some of the symptoms are coolant loss, rough running when cold (a small amount of water is sucked into a cylinder when it cools down), above average coolant temperature (causing the fan to run on). When checking your oil, pay close attention to any signs of discoloration and sniff the coolant overflow bottle for traces of exhaust fumes.
The gasket can fail between different points; cylinder to water jacket. This causes higher than normal coolant temps and can cause hard starting and rough idle when cold. If this point fails, the combustion can force hot gases into the water jacket and then sucking in some coolant when the motor cools down. The latter can cause cold-starting problems and stalling until warmed up and free of water in a cylinder.
Oil passages to coolant jacket; oil is under higher pressure than coolant which can force some oil into the water jacket. When severe, it can make Jergen's Lotion out of the oil (that doesn't help lubrication) and discolor and lend odor to the coolant.
If you don't mind dirty hands, I would remove each sparkplug from the cold engine and look for signs of rust or even dewy coolant deposits on the base of the plugs; been there, seen that.
Unfortunately, a failing head gasket won't set any error codes until severe enough to cause other problems to monitored areas.

Water in oil


Possible failure of Engine head- if there is mis firing in the cylinder.
Possible faiilure of the water jackets to the main outlet.
Possible problem in the water pump section.
So if your engine seems to fire and work fine the leak is somwhere in the engine jackets but in both the cases it needs immediate attention, to remove and identify before you have a costly maintenance.

Coolant leak on olds alero 2000


Engines are designed with frost plugs that are designed to blow out if the coolant jacket should become frozen. Look carefully using a light and a mirror (ladys compact works well) Following the block heater cord to the engine will help locate these plugs. You may find the block heater has blown loose as it is installed in one of the frost plug holes. Best of luck.
