the engine coolant must not drop it temp with blower in cab on, or the stat is bad (no way) and or the fan is locked up.
the fan must not be engaged , on cold days, (unless parked for 1hour idling) the fan can over cool the RAD that is for sure.
if no stop lights where you live remove the clutch fan, run no fan at all.
see if car runs ok that way, (carefully) if yes, rig up an electric fan.
here is all I know on the clutch

even suz words for testing the bugger.
cheers to you and good luck with kick car.
Thanks for your reply. Sadly I live near our capital "city" (630k pop), so there are some stop lights and also traffic stalls on rush hour, so I will keep the fan there, but go today with some zipties and cardboard to figure out how much to block the radiator.
Yeah I checked and the first STAT was for 4mm lip, I went to change it on the parts dealer 15 minutes before closing time to get correct one with 1mm lip.
Your reply gives me more confidence that its is the fan clutch. (The fan runs always even now that at 4C (39F)). Also when engine stopped and cold if I give full force push for the fan it only rotates 1-2 revolutions, so the clutch is always sticking.
About electric fan replacement. The set I can get here is fan + stat controller, the stat comes with T-connector to water hose. What is your installing recommendations.
There are 2 STATs available, 92C (197F) and 95C (203F). This is the fan ON temperature point.
- Which one you recommend?
- Which hose should I plug it on the G16a's RAD. Ie the one that returns hot water from STAT housing, or the lower hose that feeds colder water to engine ?
I am some what afraid that 197 or 203F for the lower (colder water) is too high for fan to turn on and might damage my engine? The instructions on that electric fan package recommends connecting it to the lower hose, but I would like to hear your opinion.
