Heating AC and Engine Cooling

195 degrees Fahrenheit.

Bad head gasket or... Crack in exhaust port in head. Check exhaust for presence of antifreeze smell or exhaust gas in radiator.

Use a hammer

Place a pan under the drain valve on the radiator (back side of the radiator, right side) Reach up and open the valve letting the coolant out. (It is meant to be turned by hand, but you might need a pliers) After the coolant has started draining open the radiator cap to allow air into the radiator. Go back to the engine and open the thermostat cap (Large cap that looks like a radiator cap, has a two step turn - push and turn again removal). Remove the thermostat located under the cap by grabbing it, turning it to break the seal and pulling it up.

To fill - close the drain valve on the radiator. Leave the radiator cap off and start filling by pouring the coolant into the (still open) thermostat cap. Note - the thermostat needs to be still removed. Have an assistant watch at the radiator and when it gets full he needs to quickly put the radiator cap back on. Then continue to fill at the thermostat cap till the engine is full. Now start the car and let the coolant circulate, refilling at the thermostat cap when the coolant has dropped. After the car has warmed up, and all of the coolant bubbles have come out, fill the coolant to the top of the thermostat cap housing, replace the thermostat and cap and fill the reserve tank to the warm mark.

Almost all antifreeze is green.

Check the wire to the sensor and be sure it is hooked up. If so remove it from the sending unit. Turn the ignition and have someone watch the gauge while you ground it to the engine. If it moves the sender is bad.

Your Oil curdles, you head gasket may leak anti-freeze into your gas, your head may crack and anti-freeze will get in your oil, the motor may crack open, your pistons may seaze up. Oil- Do a flush with Oil Flusher to clean this up. Gasket - If you are lucky. $300 Canadian. Head - If theres water in your oil, you head is cracked. God forbid. $150CAD for inspection, specific cost to your vehicle for new head. Will have to do both gasket and head in this case at least $1000CAD Motor Crack open - If she's new, replace the motor, if shes old, sell her quick for parts or fixup for someone who has free parts in their back yard.

to low on antifrezze, or air cond. compressor locked or locking-up, to low on water& antifrezze mix in ratiator, or fan clutch out, fan belt slipping, try the antifrezze amount mixed first and make sure the fluid is circulating good ,if not water pump or stuck thermostat

The cooling fan will turn off when the temperature drops to normal temperature. When the temperature generated by the device does not cause damage to the device, or when the device is no longer in use, the cooling fan will be turned off.

on the side of the block not the one buy the oil filter

You will be able to find this diagram online. Simply doing a quick image search can help you find the information that you need.

That will mainly depend on the year of the car. Go to a local parts house and purchase a Haynes manual that is specific to your car.

It should be well grounded and in a place that it can remain cool. Sometimes the fan can pull too much current and cause the relay to blow.Ê

Check your antifreeze or cooling level this happened to me.

My 08 sierra had this same message. It wasn't hot and the antifreeze reservoir was full. The thermostat wasn't reading correctly. We had that replaced and so far so good.

What kind of engine? There's steam, gasoline, diesel, 4 stroke, 2 stroke.

Yes ... they are removable for service or replacement, but they are a system requirement for the Belts and your computer requires it as part of the system.

Because GM went to a sealing washer seal system for later vehicles (including this one), one side of the hose manifold is 'stepped', meaning that it sits slightly higher than the other. Both sides use a 'standard' 5/8 sealing washer (GM, in their infinite wisdom, designed several different sizes and heights). While there may be the appearance of a very slight gap, there actually, of course, can be none if a proper seal is made. The most accurate way to test for a good seal is to use an electronic leak detector. Note: overtightening of the hose manifold hold-down bolt will result in permanent damage to the compressor body. Good luck. SDIgroup

I had the same problem, cured it with a new thermostat! If you are mildly handy you can replace it yourself. Thermostats usually cost less than $10-$15 (make sure to get the gasket with it). To find the thermostat housing follow the top radiator hose back to the engine. The housing that the hose is connected to is the housing. It's held on with 2 metric bolts, you will probably need a deep socket, I think there is a pin on the top of one bolt. If you move quickly you can replace the thermostat with out drain the radiator some (make sure the new gasket is in place prior to starting). Once the new thermostat is in place and the housing is tight you will need to start the engine and let it warm up. While it's warming up add some antifreeze mix to the overflow container to replace what you lost. Once the engine is warm, excess air needs to be bleed off. To do that open the brass valve on the thermostat housing a bit. Once antifreeze starts coming out close it. I generally wait a couple of minutes and repeat the procedure. To you lurkers who are in the know, did I leave anything out?

The head gasket is sandwiched between the head and the engine block.

its the same as you engine if you dont let the oils warm up during winter or very cold it will damage transmison.

You can get a detail layout of the AC system on the following website. Your low side port is actually located on the Accumulator.
