Had a loss of coolant a while back after lending my car out. The level remained constant since, but dipped again slightly last week, and the cat is sniffing the front so I figure I should investigate.
What I've noticed -
Car runs OK far as I can tell, no loss of power etc. No obvious shit or foam on the dipstick or under cap. Oil temp gauge behaves normally - rises to optimum and holds Can see corrosion, or leak build up on radiator, fluorescent green (coolant?) nearby in engine bay :
From my novice perspective the radiator looks shot, but perhaps there's another explanation for that crud.
So I wonder whether a) yep radiator needs replacing b) fan isn't working causing car to overheat (but why doesn't gauge move?) c) thermostat sticking or d) god knows.
You can test the fan can't you. Can somebody pls explain how to do that? (Had a look on google but couldn't find it)
Any thoughts before I take it to the garage?
Cheers, PD
