Paul,
As a reference, my fans turn on at 179.6F and off at 170F, as measured from a probe in radiator. Engine temperature when this occurs (as measured from a probe in intake), fans come on a little over 180F and off a little under 180F. You might have your fans coming on a little too late and suffering from a snowball effect where your system can never catch up. FYI, my fans don't kick in unless at idle or in bumper to bumper traffic.......never while car is continuously moving at any speed above about 30 mph. I've never seen high temps. (260F) at idle. This is where your making the least amount of heat in engine. Allow the fans to run manually at idle (prior to reaching 160F or so) and see what happens. What size is hole in front of radiator/bumper? How is air escaping front hood area? Is outlet opening(s) twice the size of inlet? John |

Oh it doesn't matter when the fans turn on it still get's hot. I have a pretty big opening in the front of my car. and openings in the hood and the fenders. The hood I opened as an attempt to cool better but it did nothing. The hood was crap anyway, 2 front end collisions. Anyway the water going back to the engine is definitly cooler then what is coming in.
IT's raining so I can't do any work, rats. |

I checked the spark plugs and they look really good. The oil looks fine, no signs of water.
QUOTE Did you see the bubbles completely go away at your fill point while engine was warming up? If you lower the level at that point about 1" and increase idle to about 1200-1500 or so, you will be able to run engine while water is expanding. If air bubbles you present then, I'd suspect a blown head gasket. You could also pull your plugs.........if a cylinder is pumping water, you'll see a rusty color on plug. no bubbles if i increase the idle. The guy at the parts store suggested that i ring the car for about 15 sec. and see if there is any buildup of presure for the cylinders. That turned out negative. No word from Meuller. |

what is the guage going to do? The car is boiling over. It is hot. It's not the guage that is overheating it.

Paul,
I didn't know you were boiling over.........never heard that in your previous posts and thought your gage was suspect. Take Brad up on his offer to help in person. The brief/vague descriptions you've described are somewhat difficult to use in diagnosing problem. Good luck, John |
