SOURCE: Service Brake system flashed three seperate times over 24 hours

2 suggestions:

(1) I would suggest someone scan the ABS system for codes. I Have an '03 silverado 2500HD Crew cab, and it needs an EBCM (Electronic Brake Control Module) "ABS module". "Service Brake System" message on dash, ABS and Brake warning lamps lit as well. May be the R/F ABS wheel speed sensor, but what you described happen, shouldn't have caused damage to it.
(2) If the aftermarket rim and tire combo are larger than stock (larger overall diameter), then this may affect the way your PCM functions. You can reprogram the PCM to recognize larger diameter running gear so trans shift points and the speedometer and such can function properly.
I hope this helps.

It sounds to me like you have a vacuum leak or maybe a vacuum line connected in a wrong location. To find this if it's a leak, have a mechanic perform a vacuum test by blowing air through the intake. If there is a leak you will here air being forced out from the leaking location. Some shops also use smoke.

Hope this helps.

Most of the time when you run a fuel system cleaner in a engine that has not had a cleaning the sludge will clog the fuel filter. I would check the fuel filter before anything and if that is good, I recommend running a complete test on the vacuum lines sometimes if there is a leak in a vacumn line it will mess with the timing advance and cause the vehicle to behave different at certain RPM ranges

SOURCE: I have 95 Chevy Lumina. March 2010 I had water

Was the car over heating before the water pump and head gaskets were replaced? Putting in a new Radiator will make it run even colder.and take even way longer than the one hour it is already taking to warm up.The computer in the car commands the engine cooling fan On/Of at a predetermined temperature.It receives this data from monitoring engine sensors such as the engine coolant temperature sensor.So if it is defective and the computer is not recognising the defect it thinks that the engine is running hot when it is realy running cold and will command that the cooling fan be on.Resulting in the fan running in 24-7 as you put it. If you want the engine to warm up faster and the cooling fan to operate normaly then I would replace the engine coolant temperature sensor and the relay for the fan circuit as well. If you need to talk to me further about this you can use the reply box below. Please let me know how this goes for you and I hope this is usefull for you. Good Luck and have a good XMASS.

2002 Dodge neon Problems with the head leaking?

It leaks what... coolant or exhaust gas?
If it's exhaust gases it's more likely to be the exhaust manifold gasket at fault.

If it's coolant leaking out somewhere it could be a hose/radiator/coolant tank, though coolant can also leak from the head gasket area.

A classic sign of a leaking head gasket is a creamy white/grey sludge on your oil dipstick. This is caused by coolant finding its way via a blown head gasket into the oil system

2002-dodge-neon-problems-head-leaking-drn4r4jcf5cpqfgonvky3zim-5-0.jpeg A creamy sludge on the dipstick - caused by coolant finding its way into the oil system because of a leaking head gasket.

Other indications of a leaking head gasket/head is overheating and rough running.

You can also try removing the cap from the coolant bottle and letting the engine idle. If bubbles continually appear this may be due to the exhaust gases finding their way into the cooling system via a leaking head gasket.

In most cases replacing a head gasket requires the cylinder head to be skimmed as well. This is because the alloy of the head tends to warp slightly.

A workshop would be able to diagnose a faulty head gasket within minutes. Having a head gasket replaced and the head skimmed isn't a cheap job.

Nowadays there are 'guaranteed head repair' additives available. Just follow the instructions on the can if you decide to use one. I personally haven't used such an additive.

Your local mechanic should have a tester that can tell you. It uses a chemical that will change color if exhaust gases are present in the coolant. Very cheap to check- should charge you for 15-30 minutes.

We changed the water pump on 1996 chevy cavalier, the thermostat was good.Then we drove it about 15 miles and it overheated .The problem then was that we forgot to bleed the system.We had it bled and was...

It could be a head gasket. To test, have or do a chemical test for exhaust gases in the coolant. It's an easy test, and I have heard that autozone will rent you the tester. All you have to do is buy the test fluid, hook the tester to the radiator cap opening, car running at normal temp., and watch the test fluid container to see if it changes color, verifying exhaust gas in your coolant.
You could also have a shop do a leak-down test and check for a head gasket failure that way.

Overheating and wont keep running after key is released

Sounds like you have a blown head gasket. In this case though, I feel that you are blowing hot exhast gases from the combustion chamber into the water jacket causeing it to heat up. In these cases, the engine will generaly get hot in shorter time than what one would normally suspect. Typically just a head gasket is needed. Have your mechanic check the radiator for combustion gases. This is checked with a fluid in a bolltle that will change colors if found. GL
