Putting non dexcool compatible coolant in the cooling system can cause problems and sludgy buildup in the cooling system but Most coolant you buy these days will say on the bottle "compatible with any colour coolant " or compatible with dexcool" and if it doesn't you can easily find a brand that will be compatible with dexcool coolant at any automotive store.
If you have allready mixed the coolant with non compatible coolant I recommend to flush ur coolant system and use a dexcool compatible replacement coolant flushing the coolant system every few years is a good practice even if you have 5 year life coolant..
When the engine is cool
Manual calls for DEX-COOL It actually depends on what type of coolant is in it now. If it's green, it's been traded out with normal coolant. If it's reddish, it still has DEX-COOL in it. NOTE: you should never mix the two types together. DEX-COOL and normal coolant can clog up the system if mixed together. Some places sell a type that is safe for either type of system, but i'd go with whichever is currently in your system, $5 for a gallon of regular coolant or $8 for DEX-COOL but it improves expectancy of your heating and cooling system (which the venture sure can use)
If only adding coolant to a leaking system it is safe because soon you will be forced to drain the coolant and fix a problem
Yes.
Your engine should be cold ( to be on the safe side) when adding antifreeze/coolant. i let the car sit overnight and then add it.
is it safe to use prestone coolant in my1998 lexus es 300
In general, a coolant is any liquid that will keep your car from overheating. While, antifreeze is a liquid coolant that is formulated to withstand sub freezing temperatures without freezing to a solid state.same thing but different name,but i guess coolant is to keep your engine cool and the antifreeze also does the same plus it keeps your engine safe from frezing as well.
it calls for gm's dex cool compatible coolant but there are several brands that are making universal fluids that are safe in most makes and models and wont void any warrantys you may have. good luck
Check your engine coolant level at the reservoir ( do not take a radiator cap off until the engine is cool )
Let the engine cool off after being run.The cooling system pressure is a result of the coolant being heated - once the heat dissipates, so will the pressure, making it safe to remove the top of the coolant reservoir.
fail safe mode is for the 4.6 L V8 engine only - it means that you have lost your engine coolant - find the cause of the coolant leak and repair it , then refill your coolant system
Coolant is used to keep an engine in a vehicle at a temperature safe for operation. If no coolant is in the reservoir, an engine will not start.
