Hey guys,

I live in Vegas where it's HOT! Yesterday myself and a freind of mine both drove our mark VIII's from Vegas to Pahrump, About 70 miles each way and quite a few steep hills. The temperature outside was around 106 degrees or so. I have never noticed my temperature gauge get so warm before. It got to the bottom of the N a few times when climbing some hills and styed around the O on the flat roads. My freind's Temperature gauge was also in the identical spots at the same time! I know this isn't accurate to use the factory temp gauge, however I don't have any other way to measure it yet. I'm going to buy a infered thermometer as soon as harbor freight gets them back in stock. Untill then though.... Is this normal? I drive my 00 expedition to the same place and up steep hills, it never leaves the middle on the temp gauge. I just wanna make sure it's OK for the engine to run at this temerature.

Thanks, Rich. :confused:
 
Not so much the engine as the engine AND transmission temps. How fast were you running? I've noticed quite an increase in temperature with an increase in speed in hot weather.
 
I've been seeing some higher-than-normal temps in mine too here in the oven - Phoenix.

I'll be installing an autometer water temp gauge soon so I can determine what the heck those stock temp gauges translate to.

We were both driving between 70-75 mph. going down the hills the cars both cooled right off, but any uphill or even pretty much flat driving caused them to run warm. Both cars have stock gears in them and have never ran warm until the heat hit today. We really don't do that much freeway driving either though. Both cars are in 100% terriffic mechanical condition and are well maintained.


Thanks for the link pepperman.... I just don't see how a factory set-up car would run that warm?? It would seem that the cooling system and the electric fan would be able to keep it cool.


When I get my infered thermometer I will let you guys know what the gauge transulates to.

Maybe the gauges just are not calibrated all that well and it's just got me nervous.
 
That is especially weird because just about any crappy old cooling system should be able to keep a car cool at speed. There's more air coming into your grille than 10 fans could produce.

I would suggest you replace your radiator if you are having trouble. Could be clogged.
 
Sounds fairly normal to me. I don't like to throw parts at a problem... much less a nonexistant problem.

The radiators are both in good condition, actually 1 of them is fairly new. Just before I purchased my car a Lincoln dealership replaced the waterpump, t-stat and flushed and filled the system. It's not the radiator. Maybe just a combination of excessive heat and maybe the gauges running a little high I hope? Both cars were at the same temps. Hopefully they will have the infrered thermometer in stock tomorrow, Then I'll know for sure.


Where can I get a new air deflector for the underneath of the front bumper cover? Is Ford the only place?

Thanks all.
 
Last week I installed a new trans cooler. I noticed a little fuzz in the lower corner of the air condencer, no big deal. I got a flash light and checked the radiator throught the inch gap between the condencer and radiator, it didn't look to bad. I then removed the upper radiator supports and holly cow, when I moved the radiator back I could then see my radiator looked like the lint screen on my drier. Loads of FUZZ all over it. It may not be your problem but you might want to check it. It looked good when I did the first quick check.

i agree, ive seen this alot, just cuz the rad is new dosent mean that they cleaned out al the crap between the rad and the condencer, if its full it cant flow
 
It looks to be clean but looks can be deceiving! I will check this out also. Thanks.

iv been wanting to put aftermarket gauges in for a while now, but i do not know how. where do i put the sensorsfor the gauges? i wanted trans temp oil temp h2o temp, others later, but i want those because they are more critical imo, at this point.
 
It's always a good idea to install aftermarket gauges IMO. The only reason that I have not put them in the mark.... well because it's a lincoln and I dont wanna cut or drill anything that I don't have too. I always installed them in my mustangs and my trucks though. Where are you guys planning on placing them? the dash or the A pillar?

I'll be tackling this sometime in the next few months - it's just really hot outside right now (Phoenix) so I'm not terribly motivated.

I'll probably write an article that you guys can post up so others can copy my work if they like. I'm not sure where I'll located the water temp sending unit yet - I might have my fabricator weld a bung onto the metal coolant tubes on top of the motor. A piece of steel rod stock could just be drilled/tapped to make it work. Either that or I'll see if I can do something with the thermostat housing. I'll weigh my options and do what makes the most sense.

OK, so what is normal operating temperature for a mark VIII? Mine got to around the (R) today and my infrared therometer had it about 215 degrees. This was at the front of the timming cover. Thats the hottest spot I could find. Does this sound like a normal temp?

Today outside around 2:00 PM I pointed it at the street (asphalt) and it was reading 155 degrees!! The actuall outside temp in the shade was around 106 or so.

I will wait until it goes up higher next time so I can check it again.


Oh yeah, I'm sure that Dr. paul could add another 5-8 degrees. It's even hotter there!

It's frikkin hot as hell here. Ugh. I walked back from lunch today and I swear my feet get scorched from walking on asphalt.

215 degrees seems a bit hot. I'd prefer to keep the car around 185-195 if possible - of course, that may not be possible with very high ambient temps.

It may interest you to know on my '93(with the AC off), the stock fan turn-on temperature setting was 215* and the fan turned off at 205*.

Is there an easy way to lower the stock fan turn on temp?

On mine with the A/C on the fan is always running full blast and the needle will still slowly creep on up there. I have read that the stock electric fan is one of the best ever made, so I would asume that it's pulling enough air. You know I had the same problem with my Bronco II that I used to own, Once it hit 105 outside it would run around 235 degrees. That was with a new heavy duty radiator twice as thick as the factory one and a fan that pulled crazy air. The radiator shop was even stumped.

I'm going to put my trans cooler on today if I have time, maybe this will help out a bit.
 
I asked that same question a while back, about turning on the fan at a lower temp. I hope you get an answer.
About 2 years ago in the Jegs cat. ( I think ) they had a thermostat that would slowly open and close, not just snap open at say 195. It would start to slowly open at about 185 and open more if the temp still went up. I think the idea is that it is easier to maintain the coolant temp than to cool the coolant down 10 or 15 deg. Plus there is no sudden rush of cool water into the engine. Might be worth looking into. I bought a new lower temp thermostat but I can't put it in, ( I can't get to some of the hose clamps and bolts) so good luck if you try this.
I might be in ST. George in a couple of weeks! Looking forward to a little heat!

Holy crap! :eek:

Damn, that not a very desirable factory setting IMHO. That's craziness.
 
Dont they run them hot to reduce emissions and for increased fuel mileage?

Still think its too hot though.
 
when it's in the mid 90's and up mine will rise up half way on the gauge. sometimes when it get's in the upper 90's or 100 plus it will go up to about the "R" on NORMAL. this is one of the reasons I run 10W30 weight synthetic oil.
