Well, After spending 3 hrs at the dentist for a root canal, I mistakenly added windshield washer fluid in my coolant reservoir. Is it easy to flush this system out and are there any bleeder valves that need to be opened in order to purge the air out of the system? Thanks, Sal

LOL, you can buy a do it yourself kit at an auto store. should be pretty simple. I've done my jeep wrangler in the past, simple stuff.

Or to be safe, just take it to a oil/lube shop and have them flush it.

I wouldn't even worry about it. Windshield was fluid is just water, some alcohol and some coloring. The alcohol will take care of itself , leaving you with water and colloring.

Depends on the type of Anti-Freeze used by Dodge on his year model.

My 2005 Dodge had the "orange" anti-freeze that would not mix with any other coolant fluids.

I learned that the hard way.

Unless you can't mix it with water it's not going to be an issue.

“Ignorance more frequently begets confidence than does knowledge: it is those who know little, and not those who know much, who so positively assert their conclusions as universal and absolute truth.”

From the factory service manual: (Cliff notes - it's ethelene glycol with some anti-corrosion additives that gets mixed 50/50 with water).
ENGINE COOLANT

WARNING: Antifreeze is an ethylene-glycol base coolant and is harmful if swallowed or inhaled. If swallowed, drink two glasses of water and induce vomiting. If inhaled, move to fresh air area. Seek medical attention immediately. Do not store in open or unmarked containers. Wash skin and clothing thoroughly after coming in contact with ethylene-glycol. Keep out of reach of children. Dispose of glycol base coolant properly, contact your dealer or government agency for location of collection center in your area. Do not open a cooling system when the engine is at operating temperature or hot under pressure, personal injury can result. Avoid radiator cooling fan when engine compartment related service is performed, personal injury can result.
CAUTION: Use of Propylene-Glycol based coolants is not recommended, as they provide less freeze protection and less corrosion protection.
The cooling system is designed around the coolant. The coolant must accept heat from engine metal, in the cylinder head area near the exhaust valves and engine block. Then coolant carries the heat to the radiator where the tube/fin radiator can transfer the heat to the air.
The use of aluminum cylinder blocks, cylinder heads, and water pumps requires special corrosion protection. MoparŪ Antifreeze/Coolant, 5 Year/100,000 Mile Formula (MS-9769), or the equivalent ethylene-glycol base coolant with organic corrosion inhibitors (called HOAT, for Hybrid Organic Additive Technology) is recommended. This coolant offers the best engine cooling without corrosion when mixed with 50% ethylene-glycol and 50% distilled water to obtain a freeze point of -37°C (-35°F). If it loses color or becomes contaminated, drain, flush, and replace with fresh properly mixed coolant solution.
CAUTION: MoparŪ Antifreeze/Coolant, 5 Year/100,000 Mile Formula (MS-9769) may not be mixed with any other type of antifreeze. Mixing of coolants other than specified (non-HOAT or other HOAT) may result in engine damage that may not be covered under the new vehicle warranty, and decreased corrosion protection.


COOLANT PERFORMANCE

The required ethylene-glycol and water mixture depends upon climate and vehicle operating conditions. The coolant performance of various mixtures follows:
Pure Water- Water can absorb more heat than a mixture of water and ethylene-glycol. This is for purpose of heat transfer only. Water also freezes at a higher temperature and allows corrosion.
100 percent Ethylene-Glycol - The corrosion inhibiting additives in ethylene-glycol need the presence of water to dissolve. Without water, additives form deposits in system. These act as insulation causing temperature to rise to as high as 149°C (300°F). This temperature is hot enough to melt plastic. The increased temperature can result in sever engine damage. In addition, 100 percent ethylene-glycol freezes at -22°C (-8°F).
50/50 Ethylene-Glycol and Water - Is the recommended mixture, it provides protection against freezing to -37°C (-34°F). The antifreeze concentration must always be a minimum of 44 percent, year-round in all climates. If percentage is lower, engine parts may be eroded by cavitation. Maximum protection against freezing is provided with a 68 percent antifreeze concentration, which prevents freezing down to -67.7°C (-90°F). A higher percentage will freeze at a warmer temperature. Also, a higher percentage of antifreeze can cause the engine to overheat because specific heat of antifreeze is lower than that of water.
CAUTION: Richer antifreeze mixtures cannot be measured with normal field equipment and can cause problems associated with 100 percent ethylene-glycol.

What did you mix it with anyway?

Thanks for making my point.

Not a good idea to run this truck, probably drain and flush it right where its at. That type of antifreeze is not cheap but you have to use it. Isn't there a Preston premix that mixes with any type of antifreeze it say. Wonder if we could use that?
