The radiator on a 1995 Saturn is flushed by draining the coolant, refilling the engine with water, and adding a flush. It is allowed to circulate and drain before refilling with coolant.
Yes. Measuring resistance involves imposing a small current through a device and measuring the voltage drop. If there were any other source of voltage, the reading would be in error. You could also damage the ohmmeter if there were an external voltage source. You should also take the device out of circuit before measuring it, so as to not bias the results by the resistance of other devices in the circuit. It all depends on the situation, for which you are responsible for evaluating before you start.
If coolant needs to be added and the owner does not know what kind is already in the engine, it should be drained and flushed before adding any new. Most coolants are appropriate, but it is not recommended to mix brands or types. Use a coolant safe for aluminum blocks or buy Yamaha brand coolant specifically for your model. The coolant should be premixed 50/50 or if it is not premixed, mix it 60% coolant and 40% water before adding.
Use the highest available voltage setting. One should know the system voltage before attempting to measure, other wise it may lead to accidents.
With a "Fluke" it still reads the correct voltage but with a "minus" sign before the figures. HOWEVER do not do this with an oldfashioned moving coil meter, it will blow up literally!
Yes, but you should measure solids before measuring liquids. If you, for example, measure water before measuring flour, the flour will stick to the measuring cup.
It's on the bottom of the radiator, and there's also a coolant drain plug somewhere on the block, but I've never flushed the coolant on mine, so I don't know exactly where. Don't forget to let the engine cool COMPLETELY before you do this. It's not just a matter of you getting burnt, you could also damage the engine if you drain the coolant or oil while its hot.
It most likely has an air bubble. Allow engine to cool completely. Find bleeder valve and open to remove air bubble. This may require adding coolant. Close valve when coolant comes out. Fill reservour to correct level and go for a spin.
Because the windings of transformers have resistance, the primary and secondary currents will cause voltage drops. To compensate for the drops, the transformer may have been designed to have a higher than specified output voltage when there is little or no output current. The no load output voltage typically is only slightly greater than the specified voltage. Before measuring the output voltage, measure the input (line) voltage. If it is not as specified for the transformer, calculate its effect on the output.
The universal coolant is a good way to go if you are not sure which it takes. The 98 Saturn has a big colored dot on the reservoir, green or orange Here's my opinion. They make a universal coolant now, perhaps Prestone or some other brand. It claims it can be mixed with ANY type of coolant... if you're not sure what it takes, go with that. Take your time flushing your coolant if it looks like mud. You may have to flush it multiple times to get all the junk out. I bought my Saturn used. When I checked all the fluids my coolant was a browish color. I ask my mechanic he told me that who had it before put both green and orange coolant in it. He flushed it and put in orange coolant.
The voltage before it is hooked up to a resistive load.
After.
