hello friends :

my lady felicia it's be normal temp on idle and from 1st gear to 3rd gear

but when i shift to 4th gear temp needle go to 90 and never come down or go up

when i switch to 5th gear the temp go normal

plz help :'(

This makes no sense at all to me; not the English, which is fine, but the fault itself. I just can't see any reason why the running temperature should be different on one intermediate than in the other gears.

What is "normal" temperature though. since you seem to say that 90C isn't on your car. It is the sort of temperature I'd expect in British conditions, if not in Egyptian.

The normal running temp should be about 90 on the guage
