My Dodge Grand Caravan has a Cylinder 5 Misfire,?
OK ,you could have a bad injector causing this too happen,you already replaced everything associated with a miss fire code and you still got a miss fire on no 5 cylinder,take no-5 plug back out and run a compression check on that cylinder and find out how much compression it has on that and each other cylinder,if its constant misfire under strain or at idle you may have a burnt valve on it,if you got good compression and the wires are new and none of them are crossed and the plugs are gaped right it has to be in the engine part of it,let me know if its doing the exact same thing as it was before you swapped any of these parts out on it,good luck
2008 Dodge Grand Caravan white smoke coming from exhaust?
If it was just a small amount of white smoke that quickly dsappates upon start up in the morning It was likely water vapor from the exhaust system. when hot metal cools off it pulls moisture from the air which condenses inside the esnaust system. Most mufflers actually rust from the inside out. Stainless steel coated exhaust systems last a little longer, its the heat of the engine usually blows out a small amount of water, and then some will vaporize into steam. White smoke or black somke can also be fuel, the difference is if its fuel it smells strongly, and the engine would be missing too. Its normal to get small amounts upon start up, its usually a lot more visible when the weather is cold.
What does it mean if there's oil in my radiator?
Means you have a leak between the oil system and the cooling system. Probably means you also have coolant antifreeze in your oil... check the dipstick for water contamination. That's a worse problem.This is bad and is a sign that the walls between the coolant and lubrication system have corroded through (from depleted coolant - too old) or your engine block is cracked from freezing or severe overheating. Both oil and coolant travel through passageways in the block and the walls between them can be thin. Another possibility is a head gasket failure.This is not a totally uncommon ocurrence I have heard, and to fix Head gasket is not too bad but the corrosion or cracked block will likely be expensive. Continuing to drive this way will eventually destroy the engine totally (it's not that far from there now, even though it may be running). The watery oil will foam and be ineffective. the metal parts will rust and eventually the engine will seize as the hole gets bigger and the leak worse.
Average cost for blown head gasket 2005 dodge grand caravan?
Labor on this job for both banks calls for 8.0 hours, parts require a head gasket set@ 185.00 it is recommended to replace the head bolts because these are torque to yield bolts (they stretch) they are 45.00 add coolant,oil change, and misc.shop supplies, machine shop work, tax and you are looking at about $1150.00 out the door!
What could be the cause of a car’s temperature gauge to fluctuate?
There are several possibilities.1) faulty teperature gauge. In this case the gauage will have to be replaced. This is relarively simple and inexpensive depinding on the make and model of the car.2) Issue with the radiator, coolant of the car. This could be caused due to insufficient coolant, leakage of coolant, damage to the radiator of the car. This will require extensive repair. In this case, it is advised to get the issue diagnosed and fixed at the earliest to avoid engine damage due to over heating.Hope this helps. :)
What problems go along with a bad catalytic converter?
A clogged catalytic convertor causes the symptoms of a loss of power when accelerating or going up a hill. This is an often overlooked cause of loss of power, can cause check engine fault codes and lights, and mechanics will often change a few parts unnecessarily , especially if it is only partially plugged. A couple ways I check for plugged cats when a low power complaint is a symptom, and other obvious basic maintenance items have been checked for service is to have someone hold the rpm at about 1800 to 2000 steady. Then check for a good push of exhaust with my hand from behind the tailpipe. A plugged or partially plugged cat typically leaves a hot sickly feeling exhaust flow from the tailpipe. Compare to a known good working car nearby, known to be performing properly and with the same amount of cylinders. That slow , hot sickly flow at 2000 rpm compared to the hard push blowing your hand away of a not clogged cat is a dead giveaway, and I have NEVER misdiagnosed a plugged cat , or made false diagnosis with this method. Another way is watching a vacuum gauge connected to the intake manifold. When revving up, if the exhaust is plugged the gauge reading will climb then begin to slowly drop as the exhaust pressure builds up. Further testing will be needed to verify which part of the exhaust is plugged. Diagnostic by codes is unreliable and until now I had not heard of it. A code p420 only refers to catalyst efficiency. And can be set by faulty o2 sensors. Removing the exhaust and testing for engine power returning to normal works. But the hot sickly flow has been most accurate with my experience, in several cases where shops had missed it, were stumped and called me to come check. They are always embarrassed for missing the simplicity, but need not, as cars and their complicated electronics and even age old problems can lead to loss of power without any immediately obvious cause.
Will exhaust leaks at manifold gaskets cause the engine to misfire?
I'm going to address the issue that has so far been overlooked. Most gasoline passenger and light duty trucks on the road today utilize electronically controlled fuel injection. Exhaust manifold leaks have the effect of “fooling” the oxygen sensor. Exhaust gas travels in pulses with high and low pressure zones. Exhaust gas leaks out during the high pressure event. Outside air is drawn INTO the leaking area during the low pressure event. The result is an oxygen sensor that reports a lean condition. (Too much air in relation to fuel). The Powertrain Control Module (PCM) will then increase fuel delivery to compensate. With a leak of sufficient magnitude, the PCM can end up substantially increasing fuel delivery in an attempt to “correct” the perceived lean condition. The engine (or that half of the engine) actually ends up running quite over- rich (Too much fuel in relation to air). Spark plug fouling can result, which in turn may lead to a MISFIRE. If this situation occurred on , for instance, a 98 Ford F150 with a V8, the following may be present. Lean exhaust code and misfire codes set on the bank with the exhaust leak present. The exhaust leak did not cause an immediate misfire. But it is the root cause of the resulting mayhem.
What happens if you drive your car with no power steering fluid?
Contrary to the other answers, steering a car with failed power steering is quite possible. It is difficult at low speed, and extremely difficult when stopped, but it can be done. You'll build your arm and chest muscles doing it for any extended period of time.My '87 Mercury leaked power steering fluid like a seive, and I was still able to drive it - even pulling a trailer - without the hydraulic boost.But the other answers are correct that doing so can and eventually will cause the power steering pump to fail. That in and of itself is bad, but it's not the worst thing, especially if you are far from home when it happens.Most modern cars use what's called a serpentine belt to run the engine accessories: the air conditioning compressor, alternator, power steering pump, and radiator fan are all run by the same belt. If one of these fails, the belt can snap, leaving you with an engine that will quickly fail due to either overheating or lack of electrical power.In short, keep at least enough fluid in the pump to keep the shaft lubricated, even if it's not enough to make the system work.
