hello!

my car have a rare problem... very very rare.

when engine is cold, sometimes start the fan whe have 60/70º , and have missfire.

i was thinking the problem can be the cold water temp sensor, located near to thermostat.

any ideas?

i try to put a new coolant liquid, clear radiator, but still the problem...

thanks very much!

 

please... any help

today I start the engine, and sounds like "ratatata"... after various minutes, go better, but start newly the fails, and the fan start at 50º!!!
