Re: coolant indicator getting to close to hight!
Were you having this problem prior to having the coolant system flushed?
If so, it is likely that your thermostat is sticking.
If not, it is likely that there is an air bubble left in your system from when it was flushed. Most of the time, air bubbles will work themselves out. You'll just have to keep an eye on it and add fluid as needed. If this is the issue, the shop that flushed your coolant system should take care of it for you as part of their service.

pink foam indicates a problem oil cooler in the radiator
it puts transmission oil in the coolant system and coolant in the transmission
the fix is to remove the radiator and flush the engine properly
replace the radiator (new one)
then replace the oil and flush out the transmission Check for water in the transmission oil first as you could be lucky that the split in the cooler only allowed oil out but closed of to stop water getting into the system
CHECK THE HIGHT OF THE HEATER MATRIX IN THE CAB , IF ITS HIGHER THAN THE FILLER/EXPANSION TANK. THEN ITS AN AIR LOCK, LOOK FOR THE HIGHEST PIPE AND SEE IF THERE IS A BLEED VALVE, IF NOT TAKE BOTH PIPES OFF THE MATRIX FEEDS AND FLUSH OUT TO SEE IF IT IS BLOCKED, AND RECONNECT LOWEST PIPE FIRST AND FILL SYSTYM TILL WATER APPEAR FROM TOP AND RECONNECT RUN MOTOR, AND KEEP TOPIN UP.
1. Does the cooling fan turn on when it over heats? 2. Check your coolant level, if it is a little low it will cool normally under transit and over heat in the conditions you are describing. Also have your coolant check for proper dilution. 3. If your cooling fan is failing to turn on you may have a coolant temperature switch issue.
Hi hypajunior, Check your coolant level ensure you have power to the fan (I am assuming it is an electric fan) if you have power to the fan you may want to check your thermostat or the coolant temp sensor,it will be a thread in fitting with a plug attached to it hope this helps good luck to you
3)Dirty coolant clogging the pump
A thermostat is the cheapest part to replace, a thermostat opens and closes allowing coolant into the motor as needed to keep it cool, if it gets stuck closed then it doesn't allow any coolant into the motor thus overheating.
A water pump is what pumps your coolant around the system, and if this goes no coolant moves thus overheating. Usually when these go bad they leak coolant and are also noisy when bad.
Lastly could be bad or dirty coolant, a coolant flush can take care of this.
If I were you I would start with the thermostat followed by the coolant flush, both of these can be done in your driveway.
