Antifreeze is leaking from the intake manifold what causes this?
most time it is caused by intake gasket failure
Where is the most probable location of an antifreeze leak on a 1997 Chevy Blazer 4 x 4 The leak is pure antifreeze leaking under the front of the engine?
Answer Check the water pump. If the water pump bearing is worn out there will be a streak of antifreeze leaking from the bottom of the input shaft. Another prime area for coolant leaks is the intake manifold gaskets. The original gaskets fail at the front corners where the intake manifold meets the heads.
Need to check all 4 corners of the intake manifold real close. The Intake gaskets are none for leaking-- common problem with that engine, Also need to check the heater hose fitting in the left rear of intake manifold.(Top side) If there is antifreeze on the lower radiator hose then the water pump is leaking. NEUTZ.
ya, especially if you are leaking antifreeze internally or externally. if intake manifold gasket leaks usually have vacuum problem result in "rough engine idle" look for external antifreeze leak at manifold gasket first. then check oil for "milky color" - if antifreeze runs low due to leak = Yes - engine overheat. Dont drive it - you can do a lot more damage if you do.
There is a heater hose that goes in the left rear back side of the intake manifold that hooks to a quick disconnect fitting, It is common for the fitting to leak antifreeze. If it is oil that is leaking, then there is a oil sending unit to the right of the distributor that could be leaking oil. There is a long rubber gasket that seals the back of the intake manifold to keep it…
Your Chevy blazer was overheating and you put antifreeze in your car 3 days ago and it is all gone Where could the antifreeze be leaking to Its not on the ground?
I have a 1996 dodge caravan and the antifreeze and motor oil seems to be mixing does anyone know what it could be?
You have 1998 Astro van and have an antifreeze leak you have checked and replaced all the belts Where could it be coming from?
That is because it is hot ( over heating ). You need to check all 4 corners of the intake manifold with your fingers to see if it is leaking antifreeze. Chevy had a problem with the intakes leaking engine coolant. There is a heater hose fitting screewed into the left rear corner of the intake and thay are none for leaking engine coolant too. You should check the water pump for leaks too.
I had that happen once. That's a bad thing. That's either cracked head, blown head gasket, or cracked block. Not necessarily. The intake on some vehicles, especially late models, the coolant circulates thru the intake manifold. You could have a leaking hose or leaking manifold gasket. You would have other problems like cooant in the oil or oil in the coolant if you had a cracked head/block or a bad head gasket.
What's under the intake is not a hose, it's a pipe which a hose attaches to behind the intake manifold near the firewall. If the hose is leaking, it's a relatively easy task to replace it. If the pipe is leaking, you will have to remove the intake manifold which is not an easy task (minimum 6 hours to remove and replace the manifold!)
