How can you tell if the head gasket is blown on a 1998 Saturn and could that be the reason it keeps overheating?
Hello All !
I have two Chevy S10 Pickup Trucks and they both have died from overheating / Blown Head Gaskets .
There are several ways to determine if a Head Gasket is " Blown" . Basically what this means is that it is the Head Gasket that that seals the surfaces between the Engine Cylinder block and the Head has a leak .
If the Head Gasket is "Blown" or leaking you will most definetly experience overheating . In both of my cases a component of the engine cooling system failed and caused the "Blown" Head Gasket . In Truck #1 , the radiator fan clutch broke and caused the engine to overheat and then subsequently caused the "Blown Head Gasket . In Truck #2 , the Water Pump Gasket leaked and the engine overheated and caused the "Blown " head gasket . Truck #1 was driven past the point of no return and we had to replace the whole engine .Truck #2 was caught in time to forestall any massive engine damage and the Head Gasket replacement did the trick . The big problem I have with all of this is that in both trucks , the Idiot gause didn't actuallly show an overheat condition . We determined from the smell of the engine that something was amiss. By the time we twigged to the Overheat condition , the damage was already done . Chevy lets us down with their poor overheat warning system . I am considering checking if this might be covered by the Magnason & Moss Act ( the Lemon Law). So far this fammily has lost seven GM cars to overheat problems . We have had 1 Corsica , 3 Grand Ams, 1 Buick Alero (a Glorified Grand Am ) and now 2 1998 S10's .
The 2000 Alero we own now is experiencing the same problems as all of the other owners on the Internet . Dashboard cracking problems , Ignition switch problems , fuel pump failure problems and so forth .
I wonder if there is a Class Action in this somewhere ?
Here are the methods I use to determine if a Head Gasket is "Blown" .
The most telling is of course overheating . You can pull the oil dipstick and look for a grey or milky colored oil and that indicates that there is a leak between the water cooling jacket and the oil system . Another method is to pull offthe Radiator Cap and look for explosive bubbling of the water ( kind of like Old Faithful ). This indicates a leak betweeb the Exhaust system and the water cooling jacket . The last method I use is to do a cylinder compression check and you can see if there is a leak from the engine cylinders .
Some of these same symptoms can also indicate a cracked block . Cracked blocks can occur during a winter freeze or if you are silly enough to add cool water to a overheated engine . You can generally add water to an overheated engine ONLY if the engine is running . If the engine will not start and is still very hot , you can cause the Engine Block to crack with the introduction of cool water to the Radiator . It is best to wait at least an hour after an overheated engine condition to try to add cool water .
If all else fails , see a mechanic . They should not charge more than $200. labor for a head Gasket Job and the subsequent head machining (to check for warped head from overheat ) should be less than $100. and the Gasket set should be less than $100. DIY cost may be around $ 200. and the cost at your favorite Mechanics Shop should be less than $500. or you are buying his KId's Braces ths year .
The Moral of this story shoud be "DO NOT DRIVE AN OVERHEATING CAR" . The longer you wait the more damage you cause .
97 Plymouth Breeze is showing symptoms of a blown head gasket and bad valve seals but is not overheating?
How can you tell if the head gasket is blown on a 1998 Saturn and is there a chance the head gasket is blown if it keeps overheating but otherwise runs perfectly?
The easiest way to see if a head gasket is blown is to check the oil, if it is light brown and milky looking then the head gasket is blown. My 1998 Saturn would always overheat. I had replaced the radiator twice and all of the hoses but it continued to happen. The people at Saturn did not know the problem. I brought it to a raditor place and the replaced the gauge that reads…
Overheating can be a number of things. Bad water pump, coolant low, fan inop, bad thermostat, leaking coolant, cooling system clogged, or a blown heads gasket. Check for coolant around the water pump signaling a bad water pump. if the temperature rises and no fan comes on, that's your problem. blown head gasket- look for coolant in the oil or oil in the coolant. it will look like a milkshake. uncap the radiator while its…
Symptoms of a blown head gasket are: White smoke from the exhaust especially at startup. Loosing coolant with no apparent leak. Oil level overfull. A white or grey substance on the underside of the oil fill cap. Engine overheating. Possible Engine miss. Air bubbles escaping from the radiator, cap off, engine running.
A cracked block means that the engine itself is cracked. A blown head-gasket means that the gasket between the engine and the head has blown. Either can be caused by overheating the engine. When an engine overheats the head can warp causing the head-gasket to give out. In some engines the heat cracks the block. If the block is cracked, it's over. If the head-gasket is blown you can always machine the head surface and…
The 3.8 GM V6 is prone to blown intake gaskets much more than blown head gaskets. The blown intake gasket causes a loss of coolant which in turn causes overheating and a blown head gasket. The problem exists with most 2000 to 2003 vehicles equipped with the 3.8 Liter V6. There were defects in the upper intake manifold gasket, throttle body nuts, and the throttle body gasket.
If it was a head gasket then the compresion would be low in the affected cylinders low compresion as a result of wear wil make the car hard to start and overheating can also lead to electrical problems, Besides blowing a head gasket, overheating can also cause a cylinder head ro crack. Low compression and engine not starting or hard to start are symptoms. As mentioned above, do not discard the possibility of electrical problems…
