I got a 97 w/2.3 and lately its been heating up rather quickly 10min to running temp apposed to 25-30min running temp. The engine dosent go past running temp at all and Friday on the highway the thermostat kicked open. Never seen it do it before. And i looked in my resivor(sp?) and the fluid is brownish. Dose this mean that i gotta change the fluid or what?

Thanks guys.

 

i would recommend changing it......while you got it out, change your thermostate......it prolly is about time.......

 

Yes, and older Rangers had huge galvanic corrosion problems. Change it soon and use the new OAT (organic acid technology) coolants -- they help prevent that.

 

Alright I figured I would have to do that. Any brands of coolant you guys recommend?

 

I think I found which one Ill use, I get stuff from this company so this is what they have
