coolant change

[al06xlrv]

06 xlrv i have owned 5 years dont know if previous owner ever changed coolant. should I drain and refill or take it to a shop that does cooling system flushes?

It depends whst does it look like. If it apoears clean and radiator and resovoir are not merky looking just change it. A flush does not usually hurt so its a toss up if the system is clean. Make sure you get an actually flush if you go that way.some shops use a cleaner to flush thst needs to be 100% removed or if left in engine can cause damage. Main concern is not useing tap water to mix with coolant

thanks mickeytee. everything looks clean I just go with the drain and refill

In reading the manual it looks like the charge air cooling system for the supercharger is a separate system? I guess I should drain and refill that also

 

[mickeytee]

Yes. Also make sure the pump runs . ive seen a lot of v that the pumps are froze up and dont even work. There is also a special coolant for superchargers ive seen . i would certainly look into that on some of the hellcat forums.

I've replaced my coolant 3 times in the last year. Not because I wanted to. I used the Harbor Freight Vacuum Fill tool. It does a quick vacuum test of the entire cooling system before you fill and then filling is super easy. No need to worry about burping the cooling system. It's a LITTLE pricey but I've used it on 2 of my cars so far. I suspect I'll use it on all of them now since all of the modern cooling systems require "burping" after filling.
