Over Heating - 5/11/2008 11:15:50 AM    jim jones   Posts: 8 Joined: 11/17/2007 Status: offline 01' discovery I flushed my radiator and changed the fluid over to dex-cool, i didn't get all of the old fluid out because it was suggested not to remove the drain plug but to remove the radiator hose. So once i started filling up i noticed the left over fluid, i continued and topped the system off, i have tried to bleed the system as much as i could over the period of the last 2 months...   But my heat hardly works now and my car over heats all the time, i sit still in traffic for 5 mins, and the car is over heating, any suggestions as to what it might be...  maybe drain the fluid again from the drain plug and start from scratch... ?

If you want to stay with Dex-Cool that is fine, but you MUST do a complete flush first. _____________________________ If it ain't leakin' it must be empty! Yes, one man can change the world.

I would remove the lower radiator hose and the t-stat housing and then do a complete flush of the radiator, heater core, and the engine block. Buy some coolant flush from the store and go from there. You know that continuing to overheat the engine will cost you $7,000 to fix, right? _____________________________ If it ain't leakin' it must be empty! Yes, one man can change the world.

Then give me a shout that will assure you of getting all the air out of the system, allowing your heater to work properly and the engine to not run hotter then it should. Also buy a bottle of Water Wetter or Purple Ice which you will add to the coolant while bleeding the system. _____________________________ Mike Retired service manager.

RE: Over Heating - 5/11/2008 1:17:01 PM    Disco Mike Posts: 9298 Joined: 4/27/2006 Status: offline Never pull over and just shut it down, that is what kills an alloy engine. If you aren't throwing alot of coolant, turn both heater to full high and high fan speed and let the engine idle till it cools down, otherwise the engine will get hotter if you just turn it off and let it sit. _____________________________ Mike Retired service manager.
