Thanks for the information. The odd thing is, the car runs just fine. When it was at hot, still performed great. The temp gauge would surge up to H, then down a bit. Kept doing that over and over. The coolant container was boiling hot. Now no heat comes from the heater inside. I'll be taking it into the garage tonight. Thanks.

Engines like to run hot actually but once you start to lose the coolant, it's a whole different ball game and one where the engine strikes out every time.

The other odd thing was the coolant never dropped below the full line. Thanks again.

Well if it's overheating the coolant expands rapidly and it may show full in the overflow tank but you'd need to check it when cold, too.
 
From what you say I'm thinking the cooling fans cut out perhaps. If you had a chronic overheat you'd never have made it home. When at freeway speed, you don't need the fans as much, if at all, to cool the car down.
 
So the general rule (with exceptions) is:
 
low speed overheat/traffic---cooling fans or other air circulation issue
 
high speed overheat-- coolant circulation issue
 
very fast overheat within 5-10 minutes of driving --- head gasket/blocked or stuck thermostat

Thanks again. I did hear the fans kick on when at a stop periodically. But I didn't check the fluid level when the car was completly cold. Will do that. With this problem, I still managed to drive it 40 miles home. Speed ranged from 35-70. I went back roads so I didn't have to stop as often.

I have a 2000 Mazda Protege. When I tried to start it yesterday morning, the engine was turning over, but it just wouldn't start. Any ideas?
 
Thanks

95 Protege won't start by merf888

I copied this from another post. I have the exact same symptoms. I would greatly appreciate any help. Have a '95 Protege ... just wouldn't start one day. Fuel pump runs when you jump the diagnostic port, EFI and circuit opening/fuel pump relays work and Ohm out correctly. Started hoping it was the timing belt but looks good and turns the camshaft fine. Have compression and spark (although suspiciously weak looking spark ... have new wires, coil, cap and rotor and plugs). Only thing I found which puzzles me is that at the connector port under the seat to the pump, I only get about 6.5 volts with the key on. It should be full battery voltage. I'm not getting any initial prime pulse or fuel pump noise while cranking .. only during the diagnostic jump. I'm about ready to try to start it while jumped just to see if it will start at all. Could this be the PCM module? I'm about to do a fuel pressure test but this has me questioning the fuel pump operation.

Solution to 1998 Protege Check Engine code P0240 by slavuta

Just want to post a solution to a common Protege Problem.
Car: 98 Protege ES, 1.8L, Manual Trans
Symptoms:
Rough idle - when disconnect clutch, the engine goes below normal idle.
Check Engine light is on. OBD-II code P0240. Light may turn off for some time.
 
Problem:
Main air intake is leaking between air filter and intake manifold.
 
Solution:
Replace the plastic pipe OR
Use medical gauze to wrap the pipe in between ribs to close air leaks. And on top of that wrap tightly with flexible duct tape.
The light should go off after 3 full cycles (car fully cools off - warms up)
 
How it works:
The code P0240 Suggests that it is one of these:
1. your catalyst is not working (O2 sensors before and after the cat read the same).
2. Main vacuum leak
3. Something terrible in the engine with the valves.
 
I had new OEM O2 sensor up front installed earlies same year for fuel economy issue (BTW-it worked!) so I didn't think that was an issue.
I drove alot and didn't see catalyst overheat.
I checked all vacuum hoses for leaks and found cracks in the intake. I decided to fix that and magically it fixed rough idling and check engine. Enjoy!
