The thermostat needs replacing any time you service the cooling system. You should also replace it if the engine is overheating, and you suspect it is defective. A blown head gasket will exhibit, certain symptoms. Coolant in the oil, white smoke from the tailpipe, overheating, air bubbles coming from the radiator, missing on one or more cylinders, a brown looking foam on the underside of the oil cap. A compression test will help to verify this.
You will need a new head gasket if you see engine coolant in the oil. I don't know about the thermostat.
I don't know which one was at fault but I replaced the head, the head gasket, and the intake manifold gasket.
perform a pressure test on the cylinders. if they don't hold pressure it's a blown head gasket
feel the top radiater hose and see if it gets warm, if not the thermostat is dead, if your head gasket has gone, check for steam coming from exhaust tailpipe.
If the vehicle does not have any bad head gasket symptoms like fluid loss or cooling system pressure build up or white smoke out the tailpipe then the head gasket does not ever need to be replaced.
i am have the same problem i change the thermostat also and that never worked took it in and they told me the cylinder head gasket need to be replaced so i did that and still didn't work now there saying that the head is cracked so after i get this done i will let you know if that was the problem.to do this it is going to costly i am in to it for about $2500.
The answer is...it depends. A majority of cars have the gasket going on top of the thermostat. You will have to look for things like a cutout for the thermostat to fit in and such to really know or you might even have to pull out the repair manual.
why do you want to. This would be a terrible idea as the 2.2 engines have head gasket issues. When the gasket weakens, the engine will start to overheat, and without a thermostat you wont know until the gasket blows and you ruin the entire engine. So you "can" run without a thermostat if you feel like blowing your engine.
what are you asking here? PLease be more specific ...like - how do I know if my head gasket is blown, or what do I do about a blown head gasket ......
As far as I know, it should have a gasket. Make sure to use gasket sealer as well when replacing it.
You will not know until your remove the head. You have to remove the head in order to replace the gasket and once you have the head removed have it magna fluxed at a machine shop. That will reveal any cracks.
Head gastket located between the engine block and the cylinder head. Going rate around $400 at a local repair shop. The gasket is cheap however the replacement is labor intensive. If you don't know where the head gasket is you definitely want it to be replaced by a professional. Saludos,KW
you will have antifreeze in your oil!
it goes out and your heat will be gon
I have a 1991 190e 4 cylinder with the same problem - in cold weather the engine does not warm up. I know that I have a head gasket leak due to oil in coolant. I changed the thermostat but no improvement. I suspect the head gasket leak somehow affects the working of the thermostat or circulation of the coolant.
There are no repair procedures. A damaged head gasket must be replaced. I know that from recent experience. You can try the various guaranteed head gasket sealants available at your local auto parts store but (a) they won't work, and (b) they WILL find a way to weasel out of the warranty. --Ken
If you remove the head then of course you replace the head gasket.Where can you get sodium silicate to fix a blown head gasket?Know that adding sodium silicate to an engine is only a temporary fix for a blown head gasket and will not permantly fix the problem. The only permanent fix is to replace the head gasket. I would never add any head gasket fix material to any engine.
You may not see anything on the gasket. Usually a head gasket "blows" because of overheating that causes the head to warp. A gasket can be bad but there should be a visable break very often in the ring around the cylinder.
That's easy actually i don't really know haha sorrry you guys *blushes*
Normally the answer is no. The only way the rings would need to be replaced is if the engine was worn severely or if you just kept driving it with the blown gasket and did serious internal damage. No way to know until it is opened up.
You will have to remove the head, inspect the gasket for breaks, check the head for flatness, and have a machine shop test the head.You will have to remove the head, inspect the gasket for breaks, check the head for flatness, and have a machine shop test the head.
Check the head gasket and the intake, both are common problems on that car
The most common cause is a leaking valve cover gasket. Try tightening the bolts ever so slightly. If that does not cure the leak, and you know for sure the gasket is leaking, then it will have to be replaced.
They don't work and are only an emergency repair. If you have a blown head gasket the only way to repair it is to replace it.
Is you Geo Tracker overheating or the temperature is running almost hot then you need to change you thermostat
