Consequences are poorer fuel mileage and possible Check Engine Light. I'd start by replacing the thermostat, and flushing the coolant system.

What's probably happening is the thermostat is stuck open, allowing coolant to freely flow through the engine. This lowers the internal temperatures and keeps the combustion process from fully completing (causing worse gas mileage). Start with that and see how it does.

Truck never reaches operating temperature


low operating temperatures is an indication of an air lock in the cooling system
gauges need the sender unit to be fully immersed in coolant to work but if they are not then the variable resistance material in the sender bulb cannot accurately relate to the coolant temperature
example if you have leak develop in a good system and you do not regularly scan your gauges like a good drive will do. it is possible that you will smell a dying engine yet when yo look at the gauge it will be reading cool to cold because the coolant has dropped to a point where the sender is no longer in contact with the coolant

Is it normal on 94 grand prix 3.1 for the temp. gauge to NOT stay at a steady temp. all the time? mine seems to go up to 210 at a stop light then go back down after i start rollin again, i just had air...


Have you checked your cooling fan to see if it is working propely? Let the car idle and get warm and listen for the fan to kick in (if they are electric) or just watch to see if the fan starts to spin faster if it is the old school type with a clutch. Have you replaced the thermostat? A bad one will let the temp rise since it opens too late and then the temp will drop off. But it won't due this only at a light and it will do it infrequently.

M\I have merz 124 model 1988 230cc i have a probelem on my odometer the tempreture is always high till max 120. is it possible to get it repaired anywhere pls help me tq


Mercedes issued a bulletin about 15 years ago about the Temperature Gauge...let's see if I can remember what they said......

''As long as the coolant is not ejected from the reservoir bottle , the gauge being in the RED zone is not cause for alarm as long as when resuming driving on the highway the temperature returns to normal.''

In other words, they expect the temperature to rise when you come into traffic or a drive thro ....but as long as no coolant is escaping, this is normal.

However, if coolant always runs at above 190F you have a problem. This may be because the aux' electric fan/s is/are not operational or the thermostat is not opening fully.

If the system is full and low coolant light is not on and you don't need to fill up the coolant often, then those points apply.

When it gets to 120 next time, get out and leave engine running and open the hood/bonnet. The electric fan/s should be running. If not you need to check for power at the fan/s or from the Temp' Sender on the cylinder head .

On these older Mercedes the fan will come on if you bump the fan boss with your hand or a rubber mallet.

One more test: With engine cold but running for about 2 minutes... grasp the top radiator hose...if it is firm you have a head gasket failure or cracked head.

How many liters of transmission fluid needs 2.4L engine? 2002 Mitsubishi Galant.


Hello, After you've replaced the trans filter and pan gasket, pour 3 Qts ATF into the fill tube and start the car. With your foot on the brake, move you gear selector from park to low and pack to park again. Leave the car running in park and check the trans fluid level. Normally after a service your transmission should take about 4 Qts, but it's easier to add more than take some out if you overfill it. Top it off to the bottom of the fill mark. As your transmission temp rises, your ATF will expand and your fluid level will rise. At that point it will be at the top of the fill line. Hope this helps, James Booth. PLEASE RATE THIS!!! :))

Are you sure the coolant isn't heating up? I had the same issue once and the problem was i hadn't opened the high point vent on the cooling system. there for no liquid was getting to the sensor ie. it wasn't reading the true temp of the coolant. If that's not it try pulling the sensor out get enough slack in the wiring so you can get the sensor into a small pan of water. put scalding hot/boiling water in the pan have someone watch the guage put the business end of the sensor into the water and see if your temp rises. If not you were ether given the wrong sensor or a defective one.

Tempature gauge doesnt rise like it should


Mostly likely being the temperature gauge isnt going to the normal position usually indicates a problem with your engines thermostat, this problem with the thermostat usually is accompanied by poor heater output so if your heater isnt getting as hot as it use to chances are your thermostat is opening to soon or is stuck in the open position which is why your temp gauge isnt rising to the normal halfway point like it should...
