Gunk up the engine sooner.
First off, check your engine coolant tank. If it's low, then that's the problem. Put more coolant in. If it's at the correct level, then look to see if there's gunk buildup. Second, is your engine overheating? If the engine is not overheating, and there is gunk buildup in the coolant tank, then you may just need to clean the sensor. If there is no gunk in your tank, your coolant level is fine, and your engine is not overheating, then it may be a bad sensor, and you need to replace it.
I find most sticker and label goo comes off with rubbing alcohol. It's never failed for me!
If the white 'gunk' is scale from evaporation then I would advise you to firstly scrape/scour it off and then do more regular water changes and thus avoid the evaporation line. If the white 'gunk' is slimey then you will need to strip down the aquarium and start off anew.
Try Gunk High Mileage Motor Flush to clean engine and Bars 2 Part Engine Fix to restore engine performance.
On engine casing, passenger's side, on flange that bolts to transmission. Probably covered with engine gunk.
You can always try fuel additives to clean out the gunk in your car's engine.

the colors of gunk you get are completely random so there is no special way to get a certain color of gunk.
Try using an engine flush. I have had luck with GUNK. Follow the directions on the can.

your head gasket has blown,get a local garage to do a compression test,hope this helps, take the oil filler cap off the engine and check for a brown/greyish gunk, if so then your head gasket is blown.
