I have a 2.0L,16v,92 corrado that has been acting up lately with over heating, the symptoms discovered so far are the fan is only activating once the ignition is turned off, the dashboard fan is always blowing cold, there is no water in the oil system and no leaks to be found? if it is as simple as the thermostat why can i not find any diagram to show the location of the thermostat on my model?
thanks for your help in advance
and patience for reading this
I wouldnt recommend the dealer right away though it is a good idea to check with them,perferrably a trusted mechanic shop that wont charge you an arm and a leg. But anyways the thermostat should be located under the car more towards your left once your face to face with it if you put it on the hydraulic lift bumper facing you-the left side of the oil pan, you will see a tube about 3 inches , water pump above it, just fallow the radiator downward and it will lead you to that tube wish i could post a picture to clarify this more. While you change you thermostat i recommend a neuspeed thermostat . stock is at about 71*C and this one is 80* delay time but once it opens it cools off so much more and at that check the water pump because it may have never been changed. and the cooling fan for any shorts. hope i could help some how.

The clutch seperating will cause slipping and hard to put in gears.But as for the overheating you need to check the cooling fan clutch when the vehicle is warm and at operating temperature turn engine off.take key out and spin the front fan it should be a little stiff to turn when the engine is warm up the fan clutch fluid would cause the fan to grab and spin more than when it is cold.
The engine has little or no coolant. The radiator fan temperature sender needs to be in contact with coolant in order to work, and the heater matrix inside the car uses diverted engine coolant as well.
Do not start or run this engine again until you've refilled the coolant system, to avoid airlocks as you do so set the heater inside the car to hot. Unfortunately, once you've refilled the system I strongly suspect that you'll discover the engine has a blown head gasket and it's not a cheap fix: it starts off expensive due the the labour costs and each additional fault caused by the failure just adds a lot more each time. Usually, you must use a proper water/antifreeze mixture, but as it's expensive and very likely to need draining down again for repairs just use water for now but refill later with the correct mixture when repairs are complete. "Antifreeze" isn't just for winter: it prevents corrosion inside the engine all year round and also prevents the engine from overheating as it's more effective than water alone.
Signs of a blown head gasket are plenty of white smoke from the exhaust even when the engine is warmed up and white creamy deposits in the oil and under the oil filling cap which is an emulsion of water and oil known as mayonnaise. You might not get both symptoms, but the easy and foolproof way to check is to get a garage to do a "sniff test" on the coolant. This is a cheap chemical test on the coolant and instantly indicates a failed head gasket.
If the gasket has failed, then it can work out cheaper to transplant a complete engine as the labour charges are far lower, but avoid so-called "cheap" recon engines. Either pay for a proper professional remanufactured engine (definitely not cheap), or fit a known good engine from a scrapped car.
Could be a problem with the reader coil for your transponder immobiliser. The Corrado's ignition key has a transponder chip inside it which is matched to the ECU. There is a small coil inside the ignition which reads the code from the key. These quite often go faulty. You can find further info on the Corrado Form. www.the-corrado.net
