Question about 1987 Subaru Gl 4WD

1 Answer

Replaced broken water pump, replaced thermostat, and the temperature gauge consistently sits just below red once it's warmed up. It never seems to go into the red if I'm idling or taking short trips, but I'm worried that it will if I drive it at all intensely it will overheat. Where should the temperature gauge read on this car? The radiator is new, and it gets hot when it's running. 1987 Subaru GL 4wd wagon, 1.8 L non-turbo.

    Okay, I fixed it by flushing out the engine and radiator with the hose and then removing the thermostat. It's not a perfect solution, but the temperature now seems to stay right where it should, and I don't think I'll miss it for the summer.

    I don't think it's the water temp sensor because the engine was actually getting really hot. Anyhow, I seem to have fixed it for now by removing the thermostat.

Hi the temp gauge should sit in the lower quarter of the gauge, it has to be a faulty water temp sensor as anything else would cause it to over heat badly

98 grand cherokee little heat.heater hoses hot top rad warm bottom is cold collant barely luke warm

While it doesn't seem likely, if you've changed, or had the thermostat changed.... I'd say you got a faulty thermostat. I am curious as to what your temperature gauge says the temperature of the engine and coolant is.. If your gauge is showing hot, I can think of two more possibilities... the water pump isn't pumping right... and, if the water pump isn't working right, the problem can be a cracked head or block, which can cause an airlock in the coolant system. Check the coolant or radiator cap.

My 1991 volvo740 bertone coupewater temp. gauge doesn"t move at all after the engine is warmed up. The upper hose is hot. The water in the resevoir is cool as is the bottom radiator hose. There was...

The thermostat is on top of the engine, just aft of the upper radiator hose. The temperature sensor (first one, closest to the front of the engine) is the one responsible for the coolant temperature gauge. It's an NTC with two resistors in it - one for the sensor gauge, one for the ignition computer. There is a second one for the Luftmassenmesser Hidtstraht system, bottom right side under the intake manifold.

If you have a drop of anti-boil on the water pump - it is coming from the weep hole and this is indicative of failure of the internal seals on the pump and it must be replaced.

There is a possibility that the thermostat is stuck closed, which can be easily verified in cool weather by cool air coming out of the vents at normal operating temperature. Check the heater core hoses - one should be warm.

Be careful when working on the cooling system - it can scald when hot! Always work on it with the engine cool to the touch and never put cold anti boil in a hot engine.

Checking the temp sensor is easy - remove the connector and place a 68 ohm resistor across both terminals (or one to ground if it is a single spade connector). The temp gauge should read approximately 3/4 across the scale. Don't short it to ground as this could destroy the sensitive coil inside the sensor. If no reading occurs, then the gauge or wiring is broken.

Yes it looks like it. Provided you installed the thermostat in the correct direction, Here's the test, remove the radiator cap, start the car and wait for the engine to warm up, When you can see the temp begin to rise on the gauge the thermostat will open. While reving the engine look for turbulance in the coolant/antifreeze in the radiator opening.
If none is observed then replace the water pump.
