Sounds like when you last had someone work on your car, they knocked the wire going to the sending unit off. Look around the thermosat housing, normally located were the upper radiator hose goes to the engine. Most cars have the temp sensor on or around this area of the engine. Most gauges show hot if this wire touches ground(any metal part of car) but some work in reverse.

How come it smoke smell like rages burning


Often times your engine , once overheated, will take time to return to normal....the high temps of your engine,will cause burnt odors due to old oil residues, anti freeze overflow etc..sometimes a simple engine cleansing will help to eliminate these odors..take care not to spill any liquids such as oil, antifreeze, power steering , brake or transmission fluids onto your engine....good luck

I have a 90 Honda Prelude si and steam is coming from the over flow tank, but its not showing hot on the gauge.


Sounds like you are having a thermostat problem. It sounds like it is sticking at times and you may also have a bad temp. sensor. At times, if the thermostat sticks in the closed position, the sensor in the outlet side of the t-stat housing will not read the proper engine temp..Next time it gives you problems, lift the hood and carefully check the temp. of both of the water hoses to the radiator. If the top hose feels hot and the lower hose is only warm, then the t-stat. is stuck in the closed position and needs to be replaced.

I was driving and all of sudden the serpentein belt ripped and the car started to shake like crazy. then it started to smoke and overheated. one of the pulleys at the bottom, not sure if the harmonic...


Power steering pulley is on the top. The largest pulley is the crankshaft pulley.
But the 2 on the bottom are the crankshaft pulley and ac compressor. Slightly
above those 2 pulleys is the water pump. Which ones not turning?
And when the serpentine belt broke your water pump was no longer circulating
engine coolant because the belt turns the water pump.

When the serpentine belt breaks you should not drive the car even
though it will run. How long did you drive the car after the belt broke?

So you replaced the belt and then started it? And you can actually drive in reverse?
If you drove the car very far with the belt broken you may have done damage to your engine. I mean
its most likely you did do some damage.

2000 nissan maxima On warm days I get a check engine light and the car smells like anti freeze . The temp gauge never shows it is hot. we have only had a few days above 65F so it has not been happening...


Replace your overflow cap. The seal under the cap goes bad and can no longer hold under pressure and will seep out a little or a lot, it also won't always give a check engine light except if it gets below the refill sensor. This is the cheapest trick to go with and then if this isn't it, at least you haven't spent $200. Do you see fluid on the ground or does the overflow tank look chalky white?

2003 Buick Century is over heating in the morning only. Radiator, thermostat and sensor have all been replaced. Water pump and fans have been checked. When it idles it gets hot but when you rev the motor...


Sounds like the intake gasket or even possibly the head gasket have gone south if everything else has been replaced. Internal engine leaks will cause engine to overheat very easily.

Serpentine belt slipped off due to anti-freeze.


Probably wet electrical components. Use an air hose to blow everything off , and let it dry good before you try it. Or, the mass air flow sensor could be dead.

My engine keeps blowing out the anti freeze through the fill tank overflow. I have a 2004 Super Duty 6.0 turbo.


start you truck. let the temp gage get to where it will start blowing the antifreeze out. than turn your heater on full blast. if the temp goes down and the water doesn't come out than you need to change you thermostate.
