engine temerature?

Dont they run them hot to reduce emissions and for increased fuel mileage?
Pretty much. I know our FOMOCO trucks at work have normal operating temps of 210* or so. My son's late model jeep runs mid-gauge at 210* plus or minus a little. Even late model road tractors run 200*-220*. The days of engines running 185*-195* are long gone.

I've noticed when the coolant is down a small amount it makes a big difference, much more than on any other car I've driven. Anytime mine starts to run a little hotter than normal I've found the coolant is low in the expansion tank, not a lot, but enough to make a difference.
 
The coolant tank is full. As for the dirt or fuzz, there was a small amount of stuff in between the a/c cond. and the radiator. I blew it out with some shop air. After I got my trans cooler installed I let her heat up to normal temp with the a/c off. When the fan came on I had about 205 degrees at the x over pipe and about 198 degrees as soon as the fan turned off. This was using the infrared thermometer. The water pump was only showing around 185 degrees. My in dash gauge was reading right in between the M and the R. Right in the middle pretty much.

Next time I go for a drive and if it warms up towards the top of the gauge I will see just how hot it is and post it.

I might try the 40 below stuff if this continues.
 
Did you look through the radiator? If there was fuzz in the space between the AC condencer and radiator then your radiator might be clogged around the cooling fins and tubes. Did you check inside the radiator? You have very hard water there if I remember. Calcium build up will cause over heating also. I only use distilled water in my car and run a 40% antifreeze 60% water mix with water wetter. I even do the flushing with distilled water.

You are correct about the hard water. I only use distilled water in my radiators, however the Lincoln dealership flushed and filled my mark before I bought it. I have the receipts for this. Not sure what kind of water they use though. How exactly do you flush a system like this without a radiator cap? Through the x-over pipe? I really dont think this is the problem but it wont hurt to do it.
 
Yep! through the cross over tube. Its an all day thing. You need to heat the engine up then let it cool down each time. Drain coolant and fill with distilled water and a bottle of flush/cleaner. Run up to temp and drain. Then fill with distilled water about 4 or 5 times running up to temp and draining. A pain in the butt I know. I believe in over doing it, rather than under doing it!

If after all of this if you still have problems, you might want to think about an oil cooler. About 50% of your engines cooling is from your oil system. B&M makes one with a thermostat and electric fan and it is not to big. With the fan you will get more cooling when stuck in traffic, a big plus where you live.

so we open the crossover and the water spills out there? how do I keep it from getting all over everything?
 
You drain it out the bottom of the radiator through the petcock and fill it with the cross over tube.
 
I drain it with the car off and cooled down.
First drain coolant.
Pour in cem. flush and fill with distilled water. Run car per instructions up to temp. You need to make sure the thermostat opens each time so the engine is flushed also. Run your heater.
Turn off car and let cool. Drain radiator and repeat heating each time to operating temp. and cooling down using only distilled water so the entire system is rinsed out. The water will feel soapy and be hazy until it has been flushed enough times.
Clean out over flow bottle.
Fill with anti freeze and distilled water. Fill with anti freeze only until your mixture % has been reached. (16 q. capacity - 8 q. anti freeze for 50/50 mix) I also use a water wetter. Check often the first few days as air bubbles work out, top off as needed.
This is why I said it takes all day. You need to wait for the engine to cool each time before you empty the radiator then refill it.
I also use anti seize on the cross over tube cap.
Even though you drain the radiator there will always be coolant/water left in the system, that is why so many flushes with distilled water are needed.

By the way, Great vid. clip! Love all that smoke!!!
 
glad you like the smokeshow :)

I just tried to take my crossover cap off and it was so stuck that the square on top where you put the ratchet is stripped now :( I think I will have to take off the tube just underneath the cap and fill it that way - do you think that will be ok?

I had the same problem on one of my Gen I's. I took it off with a pair of channel locks, then welded a big 17mm nut to the top of it. Problem solved! :D
 
Man, tough break on the cross cap. Thats why I use anti seize on almost every thing. It makes life alot easier down the road.
