i was reading about the EL diagnostic and found out that it could tell me my coolent temp so i know how hot it is rather than tell people it was on the M , A or L .

I drove today for about 1 hour constant, stop and starting with the diagnostic temp reading on for the whole trip. The Hottest temp the coolent hit was 100 and the average was about 93-97. just between the M and R on the dash gauge. This seems allittle to hot , the radiator is 1 year old, and i just put 2 liters of coolent into the car before i drove it. i have read on these forums that its ok for the temp to be between the M and the A , but mine is just past the M half way to the R . What temp should the cars coolent be if its a very hot day and been driven for awhile? hitting 100 is like boiling point of water and with coolent you can stretch the boiling point out a few degrees but should it be this high in the first place?

Its a second engine , put it in last year, and put the radiator in last year. i got the head gasket done like 1 month ago , and im scared im gonna burn another head gasket if i dont figure out a way to keep the engines temp right down.


Thanks chris.

The boiling point of water is 100 degrees at atmospheric pressure at sea level. With a radiator cap of 13psi or so the boiling point is raised to somewhere around 120 degrees. Taken in reverse, if you boil a kettle at the top of Mt Everest, it will boil at about 90 degrees. The reason being that the air pressure is very low.

So don't panic if the temp is sitting at around 95-100 degrees. The thermostat is the main controlling factor in the temp that your car will run at.

Does anyone know the opening temp for EF/EL thermostats??

so if the thermostat says 100 , its not that bigger deal? , ill replace the themostat just to see if it shows a differnt reading at normal temp., i got no idea how to do it but im sure ill figure it out.

Also just for arguements sake , are there any mods or things you can buy to drop your cooling level down a heap. Can you buy radiators that are heaps better than the stock ones? like bigger and more efficient in cooling?

Does the thermostat make a different to the temp of the coolent? or it just reads the temp of the coolent, ive heard people saying that it opens up when it reaches a certain temp, but whats that got to do with making the cooling system run cooler?

Sorry for my noobness , but i guess this is the only place i can come to for advice amd non biased technical assistance. Thanks.

My Bunky runs at 79deg. Today it was 42deg where i work and at idle it went up to 83deg, and running along it was around 81deg.

Coolant needs a flush, and the thermostat is probably stuck open, or in the wrong way, lol

Thinktank, i wouldnt be too concerned about 100deg. Was it a warm day? As stated, water boils at 100* at atmo pressure, more if pressurised (like out falcon's coolant) and even higher when a coolant is used.

Going up the SE freeway in SA (7% climb, fairly steep) @ 100km/hr on a hot day, mine will reach 106 degrees. Any higher than that and i would slow down, personally.

BTW you should never mix 2 different coolants. It's anyone's guess how they may react with each other.

I understand as told to me by a Rad specialist that on EL's the proper operating temp is between the "A" & the "M." If it is a hot day say 31C plus, it will generally hover around the "M" and might go over it a bit. But it should never go to "R."Otherwise you do have coolant problems. I dont use the actuall diagnostic temp readings cause i tend to freak out to much when I see them rising. But remember to if your Temps are running to low you will find you use more fuel

Ford specifies a 92 degree thermostat. you dont want your engine running any cooler than that. A hot engine is a healthy engine!

Just make sure all the servicable items are in good shape, and let the car do its job

Thanks for the advice.

If i was to put a new thermostat in it could help with droping the temp down alttle? , i cant remember changing it on the car ever.

But this is what i truly dont understand..

Engine gets to normal temp, thermostat opens, colder cooolent is let into the engine, engine cools , its only a matter of time till all the water in the system gets hot and reaches its maximum cooling ability? Once the thermostat opens all the water in the system now gets warm , so if the thermostat does its job by just opening how could the thermostat affect an increase in temp if all it does is open? Does the termostat not open fully when its older ?

Yeh, pretty much. They get clogged, or dont open and close fully, or they open later/sooner than desired.

They only cost ~$15, and take about 5 minutes to change. It can't hurt.

Atleast you know that youve got a healthy thermostat in there. If you're still paranoid, you can always take your radiator for a flush/service. Only ~$110. Money well spent!

There are larger radiators available.. and they are surprisngly affordable. yobboford just purchased a heavy duty 3 core for his V8 for ~$300 after splitting the end tank at the burnout comp earlier in the week. haha

It has metal end tanks, rather than plastic, and larger cores. Overall - longer lasting and more efficient cooling!

Agreed.

Yeah but so long as the radiator is working effectively there is a constant heat transfer from the coolant to ambiant air.

Yeah as they wear out they may not open properly and/or may not close properly. There's not much to em really.

As waggin said, an engine that's too cold is just as bad as an engine that's too hot.

So ive heard a hotter engine is a healthy one, but i want my car to be able to remain at a normal level on a very hot day . However now that you guys have told me about the water presure and its boiling points, i feel alttile better.

So far i have understood that these things could help
1- flush radiator and re-add coolent
2- change thermostat

Are there other factors that will give abnormal cooling ? like water pumps, older hoses , i checked my 2 fans, they seem to be both working ok . anything else?

so its easy to replace the thermostat, what do i need apart from a new thermostat?

Do i just remove the big hose from the silver connecting thingy , what do i do from there, or is it an obvious process? do i have to remove any major parts?
