Question about 2004 Honda Odyssey

1 Answer

Did your head gasket fail?

Hi, I posted the torque values to answer your question but I was wondering if your head gasket failed. Recently, I was experiencing the smell of antifreeze for a couple weeks and finally noticed one day my temperature gauge up in the red. I guess I had a slow leak and finally noticed it when the extreme heat affected the a/c performance. Well, I've discovered a coolant leak between cylinder block and head at the left front corner of the engine. I have a 2004 Odyssey EX with 46000 miles on it.

Yep. Defiantly sounds like you got a blowed head gasket. Probably a warped or cracked head as well. You need to have it pressure tested to find out for sure if it is a head gasket. If it is then you will have to pull the head off send it to a machine shop and have it checked for warpage and or cracks. The 3.5 has 2 heads. Do them both.

SOURCE: coolant leak at the front of the engine

The water pump is located along the left side of the engine underneath the plastic covers. You coolant leak is most likely a radiator hose.

SOURCE: I have a 1994 Honda accord ex. It is leaking antifreeze

If your antifreeze is leaking into your engine oil, it will destroy the engine quickly. Check the level of both. need to get a pressure gauge on it to apply pressure to the cooling system to see where the coolant is going first. White smoke is a sign of coolant in the engine oil.

Can I retorque the head bolts on my subaru forester 2003, I've just recently replaced the head gaskets?

Gaylene Green,

If you already had a heating issue... just skip over all this meaningless RE-Torque "STUFF"

If there was no overheating
before this procedure... I would suggest either the WRONG GASKETS were used... or they were somehow reversed blocking a water passage).

TORQUE has two ways to go...
Too loose = leaks (water and/or combustion)
Too TIGHT = Broken bolt/stripped threads

If it will make you happy

Sure... TIGHTEN... and then RE-TIGHTEN... after running.

That USED to be the way it was done... until they came out with WONDERFUL "Modern" head gaskets... (tighter... never looser... and NEVER (MORE) too tight.

If you think your torque is too much... you MUST also follow the REVERSE torque pattern when loosening (else risk a fractured casting (FOR REALS)).

Although I seriously doubt the desired effect...

The answer is SURE...!! Go for it... Re-Torque...

(Could not possibly hurt... unless you do it wrong!)

Just not sure of the "OVERHEAT" diagnosis...
sounds more than a bit odd.

If there is any previous history of overheating... I would pursue that as an INDEPENDANT issue.

Thermostat, defective water pump... radiator cap... or crusted up radiator (any or all of the above + rotten casting plugs in the engine).

Head torque... Naaah.

At startup engine runs rough with a white smoke out of exaust with a sulfur smell. . stops after tthe engine reaches op temp.

On a vehicle that old, especially with high mileage, the symptoms you describe are fairly typical of a failing head gasket. When head gaskets begin to fail, they will allow water to drip into one or more cylinders, which will burn off as steam when the car is first started. Check to see if you are losing any coolant, however small the amount.
If the vehicle has recently been allowed to overheat, near 100% probability that you will need to have the head gasket replaced.
If by "sulfur smell," you mean a smell of raw gasoline, the problem can also be a sticky startup injector... but less likely than the chance of a bad head gasket.

What is the torque settings for a mitsubishi colt hiline 2.0i cylinder head?

There is no torque value. Commonly, Head bolts are tightened and then removed in sequence as you step threw 3 values: 23/33/45 ft lbs then the final value is achieved by rotating the bolts 90 degrees so the final value is unknown.

You have to get either a hayes manual or follow a procedure online if you are replacing the head gasket. If you are not replacing the gasket do not "re-torque" the head bolts thinking that you can fix a head gasket leak.
