Here are the last week of events. My car blew a cooling system hose... I replaced it, as well as drained and refilled my coolant and water. Now, once in while my check engine light will come on, the thermometer shows my car getting hotter, and my RPMs go up. This will start about 10-15 minutes into the drive and then will stop only after about 10 minutes usually in the middle of the drive. If it were overheating wouldn't it become sluggish? I'm resetting the ECU codes right now by leaving my battery unconnected for 20 minutes. Maybe it's just a computer malfunction. Any ideas or diagnosis will help. Let me know if you need any more info. thanks guys
Did you bleed all the air out of the cooling system? It is critical that you do that or the cooling system wont work properly. Dont take that temp guage lightly, it is more reliable than you think. You will have serious damage if u continue to drive with high temps in the engine.
Start with engine cold and off. Set heater control to highest heat and loosen radiator cap. Start engine and allow it to come to operating temperature. Add coolant if necessary as it warms up to keep the radiator topped off. Once it levels off crack the bleeder screw until no bubbles come out then tighten the radiator cap and fill the reservoir with coolant. The bleeder screw is the first bolt next to the upper radiator hose at the engine. Never open it with the engine hot and radiator capped. Dont shut the engine off before capping the radiator.

Yes, I took it to the shop and they tried to finish bleeding the system. So far so good, no engine light and definitely no raise in temp. It looks like all is clear, I'll post if things change. What's the most effective way to bleed the cooling system? thanks!
