I drained my coolent today and changed it but the old stuff looked a little rusty. it is not oil bc there is no coolent in my oil. The car does not smoke at all and does not burn oil. One of the mechanics I talked to said to change the thermostat and I did today and flushed the system. The thermostat was original I think. Should I worry about this at all what do you guys think?

 

There is almost always a little bit of discoloration to the coolant. If you flushed it and put new in, you probably don't have too much to worry about.

 

thanks man so no worries?

also BTW I figured out the problem on ym car with the starting and loss of tach it was the otpi pos. I replaced it and no problems the car runs so much harder. Thanks for your help.


Also my locla NAPA sells complete optis for $160 new now

 

I flush my system every year. It looks like *rusty* fluid. Maybe the Dexcool makes it look that way. I have come to terms with it and accept it as a norm.

 

Mine also looked somewhat rusty when I had the coolant flushed earlier this summer. I was told it was the radiator slowly rusting out. Doesn't seem like too big of a deal though.
