The Civic 97 was over heating. I checked the car maybe a month and a half before this issue started. It hadn't been serviced in over 1.5yrs.
I did the basic airfilter, oil filter, oil, sparkplugs, checked coolant and cleaned the dizzy.
It didn't look too bad.
After the car had over heated, I couldn't work out if the engine had seized. From what I understood the driver said the car halted. She then let it cooled down and drove home.
In theory if it overheated and lost all the water the engine would have seized and it would have been thrown in the bin.
I did a cooling system pressure test and found a leaky hose. I also replaced the thermostat and the thermostat gasket. The civic uses a rubber gasket. Some cars use paper or liquid gaskets in the thermostat housing.

Description:
TRIDON THERMOSTAT 77C - 52MM (DIA), BYPASS
Bypass style thermostat with jiggle pin. Opening Temp: 77c
/techt/thermostat.htm
- Install thermostat so that the jiggle pin valve is positioned toward the high side of the housing
- Jiggle valve? this valve prevents air lock from occurring in the cooling system by allowing trapped air to escape while also reducing coolant leakage through the flange

For Offset Thermostats with Jiggle Pin Valves
Caution: Failure to comply with these instructions may result in serious injury.
1. Allow cooling system to cool before servicing.
2. Prevent accidental starting of the engine by removing the ignition key.
3. Drain and flush cooling system.
4. Remove the outlet housing and take out old thermostat and gasket.
5. Clean gasket mounting surfaces.
6. Install thermostat so that the jiggle pin valve is positioned toward the high side of the housing with the copper pellet toward the engine (see installation sketch).
7. Install new gasket or rubber seal.
8. Replace outlet housing. Tighten bolts evenly.
9. Refill cooling system and run engine with radiator cap removed to normal operating temperature while checking for leaks.
10. After engine has reached normal operating temperature, shut off engine and allow engine to cool and recheck coolant level. Add coolant if needed. Test radiator pressure cap and replace if needed. Install radiator pressure cap.
------------------ KIA ------------------
When the Kia was brought to me it had no oil. Well maybe a cup still in it :( It had been burnt and charred. Quickest tell was to look under the oil refill cap and PCV/Bypass lines. As they are clogged and extremely dirty.
Not much can be done but hope for the best. I used an oil additive which flushes the engine. I believe it is pretty much a de-greaser which turns the oil to water.
I haven't done any reading, but just my feeling.
Some people recommend 500ml of diesel into the oil and run for half our. Because of the detergent properties in the diesel. Also kerosene is another example i have come across. I used kerosene to clean the gearbox out.
Some people recommend against these engine flush additives on badly maintained engines. The sludge build up could be preventing leaks e.g. rear main, rocker covers, sump etc.
So many things could be said regarding sludged engines. Could do multiple short term oil changes.
Dont put engine flush in the old oil. Just dump it and put in new oil, run the flush then change to new oil. It all depend on how much you wanna spend and time.
