Question about 1989 Volvo 240

Can A coolant sensor LEAK?

I've got a leak somewhere around the 4th intake(?) in my 89 Volvo 240. I believe this is near the sensor. Is it possible for this to leak? I can quite see the problem, as it is a minute leak that usually steams off before I can see it. Thanks, Mark

Happy New Year!

Yes a coolant sensor can leak. That is more than likely where the problem is. Order a sensor and change it out. Mike

Coolant leak under starter


If the water pump is near the starter it is in the
wrong place,it should be on front of engine.(sorry)
You could be loosing water from a pipe above the starter
one which goes to the heater.Although minor,it is leaking
onto starter and you do not want that.You must cover or
put something over starter to stop it getting wet,and this
is URGENT like yesterday. You will short the whole car
if not.
LUCK

Losing coolant in my 2000 gmc sierra


These motors are famous for the intake manifolds leaking coolant.Have a pressure test put on the coolant system and look for a leak around the intake manifold corners.Check all four corners i've fixed many of these.

Just re done top of motor. Everything together and I start it steam dumps out of the exhaust. I believe a water hose is wrong from the radiator somewhere. Need to know how to run the hoses. 89 iroc camaro...


Steam from the exhaust means, unfortunately, that coolant is entering the cylinders, and very little running like that will destroy the rings and pistons. It could be anything from an intake or head gasket leak to a cracked cylinder.

I have a 1991 Volvo 240 Iput in a new Air Mass Meter. It idles low and it cuts off. If I give it gas it will stay running. It idles rough and shakes.


Have you made sure that you have no vacuum leaks? Check the air filter and housing. It may be a leaking fuel injector or clogged fuel filter. Check any idle sensors or throttle sensors. The idle may need adjusted on the car.

I have a 2001 Oldsmobile Intrigue that has a small coolant leak. It appears to be leaking somewhere under the motor on the drivers side of the vehicle. I ran it up yesterday and the fans seem to cycle...


Could be intake gaskets, Use a rad. cap/rad. pressure tester, dont pressurize system higher than the rad cap is rated for(psi). You might find the leak that way.

I have a 2002 mini cooper s with an 02 sensor simulator on the downsream o2 sensor. the vehicle still displays a post cat system lean (P2096) code.


This could be for several reasons. I believe that the mini cooper uses 2 02 sensors, so it's possible that you have a faulty second sensor.
Or you could have a broken or missing vacuum line or intake manifold leak.
The other possible causes are a bad engine temp sensor, when the temp sensor is malfunctioning the computer may increase or degrease the fuel supply, If you getting a decreased fuel supply on a cold engine then you would have a lean exhaust.I would suggest starting with the easy stuff first, you can use a can of carb cleaner to spray around the intake and on vacuum hoses to seem if the engine picks up and idle or decreases in idle. This will tell you if you have a vacuum leak on a hose of manifold.
IF you can find a leak then I would suggest locating the other 02 sensor and use a simulator on it also.
And lastly if this didn't fix it then a test of the coolant temp sensor and the engine temp sensor would be in order.

My volvo 850 gets hot but the indicator of temeperature works and shows that dhe temperature is in normal levels, also dhe radiator signals lights on.


The radiator signal lamp is on because the coolant level is low (there is a leak somewhere). The temp indicator doesn't show hot because the sensor probably has no coolant flowing past it to sense the temperature. This should be repaired as soon as possible before the head gasket needs to be replaced.
