Well today I decided to flush my coolant since it has never been done, with over a 125.xxx on the clock. I put in a new t-stat about 3,000 miles ago also.

I drained the radiator completely. Then I poured 2 quarts of distilled water in then 2 quarts of dex cool. I poured roughly anthoer quart of dex cool in the radiator the topped the rest off with distilled water. I started the car let it run with heater on

Now here is my problem. Driving down the interstate the temp gague is reading about 10-15 degrees hotter. At a red light the temp shoots up to 210-215 in about 2 minutes.

What is happening here? Sorry for the long post. Any help will be great.

Air in the system on the engine side of the t-stat.

You need to bleed the air out.

Take the radiator cap off when its cold.
Start the engine and wait about 10-15 minutes until you see the coolant in the radiator start to flow. (t-stat opened)
If the level drops...top it off with water.
Wait for the t-stat to close and the flow stops.
Wait one more time till it opens again and starts flowing...top it off.
Put the cap on...that should be good.

Also, keep checking your temp guage while your waiting....just to make sure you're not overheating.

Alright, I will do this first thing in the morning. Could I have put in to much coolant and not enough water? Thanks.

Depends on your climate.

50/50 for cold climates.

Half jug or maybe 1 full jug of anti-freeze is all you need in hot places like South Florida. All I've ever used is a half jug of Dexcool, the rest water.

Plus, you didn't get all the old coolant/water out by just draining the radiator. Maybe a little more than half.

Ok, Im in Alabama so I guess I didn't put to much in. I have to drvie about 60 miles tomorrow and I didn't want it overheating on me. Thanks for all your help.
