I have a 2003 1500 QC with a 5.7 Hemi.

I need to add coolant, as I have a small leak from one of the radiator plastic tank seams.
This is my 2nd radiator in this truck with this fault ARGHHH!!

Anyhow, I find that the original MOPAR HOAT coolant that was an amber/beer colour, seems to have been superceeded by a flourescent red/pink colour variety. It's NOT a manly colour for a truck lol

Both these coolaants state MOPAR 100 thousand mile/5year, have the part number of MS-9769 on the 5 litre plastic bottles and are HOAT.

What gives??

I don't want to mix these coolants if they are not compatable?

The stealership that I bought this new colour coolant from says, I "Should be" OK??

I know that there are a lot of clued up people on here so I'm asking, is it ok to mix these different coloured coolants?

Help???

Al.

 

I will be honest is saying the last time I did a flush and refill I used regular Prestone coolant. Ive never used the HOAT stuff.

 

Yeah, I've changed my opinion on HOAT. It's so hard to get, and damn expensive. This spring I'll do a good flush of the HOAT and just go with something decent like Prestone.

If the new bottle says HOAT on it, and you got it from a dealer, I'd feel fine using it. The color is a dye anyways, and really related to the contents. Dodge may have change the color to make it more visible.
