Ford Excursion :: 2000 - Overheating At 252k Miles - Radiator Replacement?
Aug 9, 2015
I have a 2000 Ex with 252,000 miles. Where it is extremely hilly (Ozark Mountains). I tow a 6400 lb travel trailer. What I am having problems with is the Ex is running extremely hot when towing and climbing hills. Not in the red, but damn close. No problems what so ever when not towing. No problems when towing on level ground. I know the Ex is working hard, but I want to keep it running cooler. I have flushed the radiator literally 20 times and have done 2 chemical flushes. Is it time to just replace the radiator? How many passes does the stock radiator have? What about a bigger water pump? I have the 5.4 motor, which I love so no bashing my little V8. It has all the power I need. I don't need to climb hills doing 90mph.

For a while now I've been having issues with my truck overheating. Generally when I slow down, come to a stop, after driving a while. The other I replaced the radiator cap, as coolant was bubbling out after driving far. Thermostat was replaced. Radiator was flushed today as there was some rusty color build up. Added engine oil as it was VERY low the other day. So far I'm still getting the overheating issues and it seems to happen more so when I run my AC. I've noticed no significant leaking from anywhere else after replacing the cap. I'm thinking of either the water pump or the fan? But I dont know how to know for sure and I dont want to replace parts that I dont have to as a waterpump alone is $50-60.

My 2000 Accent with 164,000km is not overheating but is dumping coolant into the reservoir so that the radiator is about a quart low. I did have a few problems with it overheating in the past month, but that was solved by thermostat removal (always above 80F here). I stopped before the overheats reached the redline and allowed the engine to cool before continuing, no known adverse performance during the overheats. No water in oil.
Failed troubleshooting:
Drained and replaced coolant x3
New radiator cap
* No thermostat.

My Camry seems to be overheating. When I'm driving the gauge maintains and reads 6/10, when the engine is idling, it goes upto 8/10, radiator fans kick in and then temperature goes down to 6/10 and keeps cycling over a period of 5 mins.
It's got 100K miles, water pump has not been replaced yet.
I checked the hose temperature; top hose 210 F, bottom hose 192, fans kick in when top hose is around 215 F.
I checked the engine temperature where the sender is installed and it was reading 205 F. Coolant level is OK. I burped the system. Previous owner told me, he had thermostat replaced by dealer.

Today while I was working I walked back to my truck after finishing the job and saw a red fluid leaking from behind the front bumper, I crawled underneath and saw that it was leaking from somewhere between the plastic cover for the fan and the radiator but I couldn't find exactly where it was coming from, I drove 30 miles before I got to the job site with my ac on, and my ac was making a noise that seemed like a whirling noise but I kinda brushed it off as the condenser going bad or whatever. After I found my truck leaking I decided to drive 20 miles to the next job site but this time I left the ac off and nothing happened the temperature gauge didn't even go up, I checked underneath when I finished driving and there was no more coolant leaking from the radiator. I drove it an additional 50 miles before I got home and still no leaks. Could the bad ac system cause coolant to leak? I have a 2000 excursion 5.4L V8

I have a 2000 Excursion with a 7.3 diesel. I have 245k on the clock. Engine and transmission are original. I have an overheating issue when I am towing and pull a long grade. It's not as bad as it was before but it still happens and I am tired of turning off the AC and putting the heaters on full blast to support cooling when it is 90 plus outside. A list of things that I have done so far.
Newer water pump and thermostat.
New tensioner.
Installed a new trans pan with about 7-8 larger capacity.
Used some magic juju juice to clean out colling system.
Installed a coolant filter. I am on my 5th filter. The first one didn't last 500 miles before getting stopped up.
Switch to Delo ELC.
I recently had the upper hose off and when I looked inside, I didn't see any scale or build up. I also read about some of the trucks of that vintage didn't get a trans cooler. When I looked, I saw a cooler but it doesn't look like it is plumbed through the radiator.
I want to install a large trans cooler. I don't want to replace the radiator just for the sake of replacing it. Also, look at the pic of the water pump with the thermostat sitting in it. Is the thermostat supposed to be resting all the way down? I keep wondering about that.

I borrowed a friends 2000 Excursion with the Triton V10, along with his 3300lb, 28' trailer to tow a car from Ashland, OR to Reno, NV to begin a restoration project. His Excursion has 175,000 miles on it and made the trip down flawlessly, but as they say, "No good deed goes unpunished." When attempting to return last Sunday, had to turn around due to overheating problems. Analysis at a local automotive shop concluded a bad radiator cap. Attempted the return trip Tuesday and the same thing happened (only got farther due to the new cap and ability to hold pressure longer).
Finally got into a Ford dealer and have been informed that the truck has a bad head gasket causing pressure to leak into the cooling system. They suggest replacement of with a remanufactureded engine as opposed to replacing head gaskets, due to the time on the entire engine (who knows what else might be bad?). The vehicle can be driven around town for miles with no problems. But put that heavy load on it and grades and it spews out nearly "all" of the coolant.

Truck has recently developed a weird overheat issue. Ill try to give a s much background as possible:
I changed the heater core in the winter and that definitely cured the lack of interior heat issue the truck had since I got it. Blows hard and hot now. (I suspect I should also swap out the rear one too)
On occasional since then I have noticed the odd time a "gurgling sound" in the heater core area. Its not all the time but here and there.
Within the last 3 weeks or so I have gotten a check engine light. I've been a bit too busy to address it, and don't tend to drive very far (work and back) but have downloaded the comp and have a P0174 and P1299. Now just in the last 5 days I have noticed the temp gauge , which is normally firmly parked at about 1/3 in the zone has moved up to nearly the hot area. I can easily bring it back down by using full heat. I have cleared the codes and they haven't returned yet, but I'm suspicious of them non the less.
What can cause lean on only one bank? I have looked at the usual suspects and don't see any obvious leaks. Is it very common to have a intake gasket leak? what's the easiest way to check for that?
My rad appears in good shape although the AC condenser is pretty beat up. I'm definitely going to flush out the coolant, it looks good and used.

156,000 miles, I've been pulling a 21ft bass boat in the summer for years with no issues. Now on hot days (over 78 degrees) it is over heating. Can't use AC and need to slow down to 60 mph in-order to cool her down. Never have flushed the radiator but I'm wondering if getting it flushed is a waste of time and if I should just proceed to replacing the radiator? For a couple of years now I can hear a roaring sound (like a jet engine) on really hot days, when I start out driving. Could this be a cooling fan? Seems like the power is restricted during these times. Really need to increase throttle to get going?

, 211,000 miles and the third radiator that was put in this truck is leaking!! Has there been a recall This is not right. I haven't even had the truck five years and this will be over 5 grand in radiators. Is a person suppose to budget an extra grand a year if they want to own a ford diesel?

I was just outside and noticed a little puddle under the front of the truck. I crowled under her to find orange coolant on the seam of the radiater right above the drain. I thought maybe the drain was open a little but no, it was tight. I have 40000 miles on the truck.

Replace them? Have a new set on the shelf, however, the 252k ones that are installed now give no high ohm readings.

2003 F-150 Supercrew w/4.6 V-8, 2-wheel drive, 219,000 miles and very well maintained. I'm getting an intermittent overheat condition that I can't figure out. Coolant level is good and I just replaced the thermostat. My OBDII app showed it running at a constant 207 degrees (195 thermostat) after the thermostat. Appears to have good pressure at the cap. It ran great for 30 minutes at idle and then did fine for a five mile test drive.
The next day in the morning it overheated within 3 miles of the house (heat was on) and you could smell it. Pulled over and let it sit for 20 minutes and started back up and it stayed constant at 207 all the way to work (11 miles). It sat at work for about 7 hours and ran great all the way home (without heat, with heat, with air cond). Then this morning it did it again, overheating about 3 miles from home. This time I pulled over and shut it off for about three minutes. Turned the key on without starting and the temp was already dropping again. So I started it up and it continued to drop down so I drove to work with no more issues. This afternoon again went home and it never overheated.
I'm expecting it to overheat again in the morning. I'm gonna go live on the OBDII for temps during the drive tomorrow.

I have a 1994 F-250 that we have changed the thermostat, radiator, water pump, cap, hoses, and installed a spring fan. New heads. Hot heat in the heater. It runs normal at highway speed for around 10 or 12 miles and gets hot. pull up and idle and the temp retracts. Even the block has been blown thru. What could possibly be the problem?

So the story goes like this, my teacher was trying to scrap a truck that he had sitting on his farm so i got it. I've been using it for a DD for the past year and a half and not I'm starting to do rust repair starting with rocker panels. But, what i was really wondering is how involved would it be to replace the radiator core support? Main reason being last time i was under the hood replacing the pass side valve cover gasket i hit it and knocked a hole right through it so yeah I'm thinking is about time to replace it.

My 1992 Nissan Primera 2.0 slx is overheating, probably on its last legs. First time this happened the radiator overflow tank seemed low so I topped it up with glycerol and added some leak plugger to the radiator for good measure. The car drove just fine for 20-30km then it happened again. At the same time, and I don't know if this is relevant, the windscreen defroster, which should bleed warm engine air, now only gives cold.

Recently, my radiator fan stopped working. Its a 2013 Elantra GLS with 54K Miles on it. Summers are scorching in my region (hovering around 50 C so I take extra care anyway. Was surprised to find out one such scorching afternoon that the fan stopped working so even the A/C failed. Took it to the mechanic, who diagnosed and said the fan motor is spoil. I was hoping it was the temperature sensor.

Experiencing cooling problems with a truck this new? My 2 month old supercrew 5.0 began over heating on a road trip last week. After about 400 miles of driving I see coolant temp start climbing until the overheating warning popped up. Pulled over, turned engine off, popped the hood and did not notice any obvious signs of overheating. Ended up waiting about 15 minutes, started truck up again, temp gauge reading 1/2.
Get back on the road, within 5 min temp starts climbing again, reaches ~ 3/4 then all of a sudden returns to 1/2. Continue on 10 min later temp gauge climbs from 1/2 to overheating quickly. I pulled over again same situation no obvious signs of overheating, but allow sometime to cool off. Started truck again temp gauge reads 1/2. Continue driving and temp gauge seems possessed, going from 1/2 to 3/4 back to 1/2 to almost overheating as I nursed it to the next dealer that I could find.
Dealer tech was able to mimic the problem and believes that coolant is not flowing properly. Thermostat replaced, water pump pulled and inspected, air bleed out of the system, all with no improvement. Now heads are being pulled/replaced to see if this solves the problem. Its depressing to have my new truck with 2,382 miles sitting under the knife at the dealer.
