Default Does the engine fan on a 1998 Honda civic lx supposed to run constantly?

2008 a crack radiatior lead to a new system being paid for and installed. 2010 the car runs hot and the driver rigged the fan to run after saying it over heat. I discover I am dumping fliuds but the mechanic at Midas in Columbus only fixes the top hose. Still it continues, I have no idea nor did the mechanic the jumper was installed . I found it but the fans constantly runs. IS this normal1 and 2 what could cause me to lose all my coolant in two day no puddles even when I idle the engine for hours I get over 40 then its dry the next day. I am worried bout paying to have the mechanic swap part after part until the stumble on it. I also wnet in for a tun up which he said I did not need but my hand held diagnostic said the number 2 spark plug misfires I will change them all in about a hour or two but when I do what about the leak or lack there of. I have a thermostat and two sensors I was gonna put on to make the fan run as suggest but it is running and does so if the ignition is own. I am more lose than ever.

Something is not right here.I am not experienced,but i can see that there is a leak of coolant somewhere,causing your engine to overheat.Take a good look at your exhaust gases.Do ou notice white smoke coming from the exhaust when you start your car? If it is cold out, this may be normal. If the smoke does not disappear after the car is warmed, you have a problem.I can think of simple problems,like a gasket,a seal or something like that but,things may get serious if coolant leaks into your engine.Your head gasket may need to be changed,transmission fluid may be entering the intake manifold through vacuum modulator,so you may have to change this regulator,or in worst cases,it may be a crack in your cylinder head or in the entire engine block.All these if you notice this white smoke.If not,your engine may be overheating due to a broken thermostat,a sensor,or,maybe he is right and spark plugs misfire leading to overheating.Here's one to check if this happens.Take the used spark plug which allegedly misfires and take a good look at it.If electrodes have glazed appearance and the core nose is too white,it is overheating then.In that case,check your ignition timing and fuel mixture(it could be too weak).If you see a crack on the spark plug,or its core nose is split,coolant is leaking,so here's overheating again.Don't throw them away before checking.Of course it could also be a hose
