Well, I can't seem to figure it out. I've never had a problem with overheating before, and this new problem is wracking my mind. I have changed out old and cracked hoses. Replaced the thermostat. Replaced several heater bypass hoses. Tomorrow, its getting a radiator flush. What else could be the issue? Will I need to find a new engine soon? I can answer some questions but you may need to explain what you may want me to check.

Do you have the proper amount / level of coolant?
Did you try "burping" the cooling system?
Is the coolant level going down?

Ok. Coolant level is good. I don't know what burping the system means. Also the coolant is flowing when I hit the gas. It drops a bit during high flow, then levels out when I let up.

how do you know you are overheating. you don't give much info in your post. if you are depending on the stock gage to tell you the temp you are relying on a component which is known to be faulty a lot of the time.

And if you know for a fact it's overheating did you have a major overheat incident before you repaired the coolant system?

Well....the overflow bottle is boiling. The gauge, while faulty, reads fine after a good whack. The car only overheats on the road. Idling is fine, no problems there. The overheat incident was when I was in Tucson. I had both lower radiator hoses blow as well as one of the bypass hoses. When I picked up the car the following friday, I blew another bypass hose. I finally got the car home last night after replacing the thermostat and upper rad hoses. When I got home the overflow bottle was boiling again, but the temp was not in the overheat range. Above normal for sure, but not to the point of overheating. After the flush tonight, If it still overheats. I need ideas as to what the problem is. Should I replace the radiator or the water pump/Timing belt?

no way the overflow bottle can be boiling. you might have a blown head gasket

I'm trying to figure out why you would say no way to the boiling. I watched it boil. but now i've got other issues. wont start. engine is flooding consistently. when it runs, its rough and occasionally pushing sooty black smoke.

Are you watching it boil, or just watching air come out of the hose and create bubbles? And unless you get a temp reading on the water in it you have no real way to confirm it. I would be guessing a blown H/G too, do a coolant system pressure test and bleed the air out of the system.

skygunner58203

well. Had it checked out. Radiator is fine. so is the head gasket and whatnot. Fan Clutch is bad. So, now I have a question. I'm going to do the E-Fan writeup on xenonz31.com. If I buy a 16 inch Hayden Fan kit and the relay kit, will that work in place of the taurus fan? Its rated for 3.0 engines with about 1400 CFM.

I also had one other question not including my thread on the digital dash. Would a faulty CHTS cause my rough idle, gas smell, and constant dying of the engine. The car drives fine in the morning when I first start it Its as the day goes on and it gets warmer that it starts failing.

Well, I hate to be back for the same old thing. But here I am. Just dropped 1500 into the ole girl and was told by the shop it was now fixed. guaranteed to run cross-country. We drive 50 miles out from Sierra Vista and lo and behold the same damn thing happens. Didn't Overheat this time. Smelled Coolant, then the rad light came on. Pulled over and steam is pouring out the passenger side. Bottle is overflowing and one of the upper rad hoses is bulging to like almost 2-3 times normal. I'm at my wits end as I am now sitting in a hotel after towing the car back to the shop. So far we have replaced every hose both above and below the plenum, all upper/lower rad hoses, thermostat, water pump(timing belt too) 90% of my vacuum lines and some air hoses. They tell me the head is fine and the radiator has proper flow. Any Ideas?

Your electric fan is too small or not coming on. Did the temp gauge start reading high before you noticed? Maybe something stuck in front of the radiator or its dirty? Did they bleed and pressure check the coolant system after they are done?

rogerz

thermostat?

skygunner58203

I don't have an electric fan in my car. no, the needle didn't say it was hot. Said it was dead center normal. I don't know if they bled the system of air or not. I'm hoping its not a thermostat or a head gasket...even tho they are saying its not the head.....

skygunner58203

Hey all, just letting you know that the issue is solved. The radiator which was fine before, suddenly bogged up with crud. When they replaced it (for free, which was an awesome bonus) They found that a rust deposit of some kind had fused with some stop leak and closed it up tighter than a virgin in church. One new part later and we are finally on the road home. Still trying to figure out how that much stop leak got in my system.....
