Do I Have To Refill Radiator With Special Antifreeze??

Flushing Radiator, Never Seen This Color Of Antifreeze....

 

Yes - like most German cars, it does not take the cheap stuff from Walmart. The manual calls for ...

Selection Of Coolant

Use only coolant approved to MB 325.0, such as Valvoline
GO5, or an equivalent extended life coolant. Refer to the
recommended Fluids, Lubricants and Genuine Parts for
correct coolant type.

CAUTION!

Failure to use the proper antifreeze could cause
radiator plugging and engine overheating. Do not
mix antifreeze brands or types. Do not use plain
water alone or alcohol base antifreeze products. Do
not use additional rust inhibitors or antirust products,
as they may not be compatible with the radiator
coolant and may plug the radiator.
Adding Coolant

When adding coolant, a minimum solution of 50% ethylene
glycol antifreeze coolant and water should be used.
Use higher concentrations (not to exceed 70%) if temperatures
below -34°F (-37°C) are anticipated.
Use only high purity water, such as distilled or deionized
water when mixing the water/antifreeze solution. The
use of lower quality water will reduce the amount of
corrosion protection in the engine cooling system.

NOTE:

require more frequent coolant changes.

thanks goldwing. i appreciate the quick reply. should i be worried i added DEI radiator relief????

 

Other than using midrange gasoline, I stick with the recommended fluids. Someone else who knows what that additive is will have to advise.

 

If there is an issue you will know soon. I may not be the best person to listen too, antifreeze is antifreeze in my book. As long as it is clean and you use distilled water only your good with 50% to 70%. I run richer incase I add water on the road for some strange reason and above 50% prevents rust, I avoid being close to the line.

Od Schoo Woody ( before the L was created )

 

Woody you know youre the man! But I disagree about antifreeze is antifreeze. This stuff is specifically formulated to protect certain metals from corrosion that occurs when its constantly in contact with a liquid. From what I read GO-5, which can be found at pepboys, is the newest 'latest and greatest' for specifically aluminum blocks, like ours has.

Now... If you use the wrong type I don't see the antifreeze eating away at the engine lol, but...... Its possible the tarnished metal would gunk up the antifreeze, eventually, right?

Which means the enthusiasts on this board would be ok anyways since they change it at a regular schedule.

It only takes about 25% antifreeze to prevent corrosion, so here in Arizona I use as much water over antifreeze as possible. The reason for the higher antifreeze % is for actual avoidance of freezing.

 

I thought antifreeze also raises the boiling point and the thermal efficiency of the water, therefore being good in hot conditions, too.

 

In the SRT6 Service Manual (and other sources) it states that nothing cools an engine better then distilled water. Antifreeze lowers the freezing point and provides corrosion protection. Pressure; (16LB) in our case, provides a higher boiling temp. (just like Grandma's pressure cooker).

Since my SRT6 is never exposed to freezing temps, I run 75/25 - - distilled water/anti-freeze.

Never combine Water Wetter or similar products with the anti-freeze in our Crossfires..

 

Why not????!?! Now you have me worried. I put a bottle of water wetter in months ago. I have never heard of compatibility issues, but then again it doesn't mean it is not possible.
Could you please point me to the article, so I can read up. I may need to flush my coolant system.

Thanks!

Cut and paste from our service manual

(Hey Woody - this is good reading and may help you with your cooling issues)

OPERATION
CAUTION: The cooling system is designed to function with a 50/50 mixture of MoparT Antifreeze/Coolant, 5
Year/100,000 Mile Formula (MS-9769) or equivalent, and distilled water. Higher concentrations may result in
poor cooling performance and premature water pump seal failure. This antifreeze/coolant may not be mixed
or substituted with any other type.


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. The coolant then 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 require special corrosion protection. Use
coolant approved to MB 325.0, such as Mopar part number 05066386AA, or an equivalent Extended Life Coolant
with the HOAT inhibitor system. 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 a fresh properly mixed coolant solution.

CAUTION: Mixing of coolants other than specified (non-HOAT or other HOAT), may result in decreased corrosion
protection, and engine damage could result. The subsequent engine damage may not be covered
under the new vehicle warranty.

COOLANT PERFORMANCE
The required ethylene-glycol (antifreeze) and water mixture depends upon the climate and the 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 the 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 the cooling system. These act as insulation causing the temperature
to rise to as high as 149°C (300°F). This temperature is hot enough to melt plastic and soften solder. The
increased engine operating temperature can result in engine detonation. 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 the
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 the 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.

COOLANT SELECTION AND ADDITIVES

CAUTION: Do not use coolant additives that are claimed to improve engine cooling.

OPERATION
Coolant flows through the engine block absorbing the heat from the engine, then flows to the radiator where the
cooling fins in the radiator transfers the heat from the coolant to the atmosphere. During cold weather the antifreeze/
coolant prevents water present in the cooling system from freezing within temperatures indicated by mixture ratio of
coolant to water.

Sometimes we want the snake-oil to work - but has the outlaw Josie Wales said: "Hows it on stains? spuuut"

 

looks like an option is Zerex G-05 is the original full chemistry in newer Ford & Daimler Chrysler vehicles.

1. how many gallons if you drain the radiators does it take,
2. and is their a stop **** to drain with
3. is it easy to do, and do u have to purge the system

 

DaimlerChrysler’s rationale for its G-05 HOAT/distilled water mixture recommendation:

Honestly don’t know if it makes all that much of a difference, as I’m not a chemist.

Another thing about water wetter, is that its a very old product. Newer coolants like GO-5 may not have even been around when water wetter was developed. When I used it in my mustang, which is an aluminum engine that uses GO-5 antifreeze like the srt6, it slightly gunked/browned up my coolant. Next time around I used "hyperlube" which is a new product ,and it actually cut down a few degrees (according to dashhawk monitor) and did not gunk anything up.

 

Thank you Brian!

This might seem good but it goes against engineering wisdom.

If the additive is increasing (improving) the rate of heat transfer from the engine's metal parts to the coolant (thus, running the engine cooler), shouldn't the coolant temp then be hotter? The gauge on your dash measures coolant temp. (assuming same fan, same amount of coolant, same radiator, pump etc..)

Do you want a cooler running engine or cooler coolant?

For true measurement; install a cylinder head temp gauge and a exhaust gas temp gauge. This is how we monitor/adjust/tune our engines in flight...


Your welcome..

 

has anyone tried the new peak for all cars

 

i had my ic pump changed a while back , and it had blueish color antifreez from the factory, i notices the tech did not clamp the hoses before he pulled the old pump so some antifreez was lost. after replacement the fluid looks clear/ grayish...
i checked the freez point good to -27 degree's

does the dealers use a clear antifreez,, this was in a mopar jug ..
i know they just did not add water and if they would have it would have been blueish.... and not a good freez point,

i thought i read somewhere their was a clear / grayish antifreez from dealers..

thanks

 

I will bet money they used the wrong stuff. I would flush it out and refill it myself with the correct coolant!

 

it was mopar
the freez point good to -27 degree's

 

I stand by my statement.
