when I start it up and start driving.....the temperature steadily climbs to the far right side (210)
And it will stay in there for a few miles. Then it will suddenly drop down into the normal temperature range (<160)
So i tried to check out the antifreeze by opening up the covering just before the radiator....i could turn it but not get it off. I thought maybe thats the way it was supposed to be, just to vent it
So i checked out the resuvoir. It had a gunky buildup around the outside and the coolant looked to be a dark brown (i KNOW that wasnt a good sign)
So I took it in for a coolant flush (and also got an oil change
)HOLY SHIT....what awaited me there was quite shocking
THe inside around the cap was crusted over with a brown sludge. THe radiator had brown sludge on it......
The attendant told me that my vehicle takes Dex Coolant and it should be an orange color. So as they are setting up to flush it... I start to talk to them and ask about it. Why in the hell would it become sludge like that. They told me it could be of two reasons
1- When dex cool levels are low, it could turn into the sludge
2- When dex cool is mixed with traditional green antifreeze/coolant, it could turn into sludge
So as they are flushing the system...they told me about how another woman came in with a similar problem...but it was so far along that traditional flushing didnt work and she had to spend around $2000 to get it powerflushed (much stronger systems)
So the system is flushed now....and i havnt noticed any problems with the temperature guage. I will check again tomorrow.
But I am still nervous. I hope the flush fixed it. I dont really have another 2000 to spend to get it powerflushed if its still a problem
Anyone else have dex cooled systems? Anyone else know any more info about it?
