Okay, you say at an idle only, what about driving,

-whatabout driving

-what temp are you running, (check with thermometer in rad also)

-is it boiling over

- is the t/stat working

-is the rad plugged, do you have good flow

-is the waterpump working, is the impellor stuck

- are the waterjackets filled with crud, has the water tube been pulled and examined, has the block been flushed

_ is your timing to far retarded

-is the gauge accurate

Let us know all the symptoms, what work has been done on the engine and cooling system to date. This way we can advise accordingly...............The Rock

Okay, you say at an idle only, what about driving,

-whatabout driving Haven't been able to drive it because we are afraid that it is overheating at an idle and don't want to crack the block/head.

-what temp are you running, (check with thermometer in rad also) Gauge doesn't work and we have to get a new one. We will have it on Friday. They had to order.

-is it boiling over Yes but maybe because it is too full??? we filled it up before reading that it should be 1" below the filler tube.

- is the t/stat working Where is the thermostat?

-is the rad plugged, do you have good flow Going to check today and see what we can find.

-is the waterpump working, is the impellor stuck Didn't want to pull that apart until we know for sure that the truck is overheating per a gauge.

- are the waterjackets filled with crud, has the water tube been pulled and examined, has the block been flushed Going to check today.

_ is your timing to far retarded Does this affect at an idle or only when driving...

-is the gauge accurate

Let us know all the symptoms, what work has been done on the engine and cooling system to date. This way we can advise accordingly...............The Rock

This is what I know for now. Working on it more today and we will see if we can make any improvements.

Okay, get a meat thermometer, and put it in the top of the rad, this will give you a temp reading, even though you don't have a gauge yet.

If you have filled your rad right to the top, and there was no coolant in the system for a hwile, the engine warms up, the t/sat opens and the coolant belches out a quart, could be too much coolant, it will find it's own level.

The t/stat housing is attached to the top rad hose on the front top of the engine, maybe just leave it for now.

What is the outside temp in your area today, idling usually overheats the engine, when it is very hot outside, and the engine is idling a long time. Don't forget, when idiling, there is not much work on the engine, less work=less heat, unless you block and rad are so plugged nothing can move.

Get it running again, feel the rad once the engine is warmed up, is it warm/hot at the top, and progressively cooler to the bottom, are there cold spots indicating plugged passages.

Not sure how you will check your block for crud, try and drain some coolant from the petcock on the block, on the drivers side of the engine, just infront of the distributor, if it seized don't force it too much and break it. See what flows out, if it opens, it should be a good stream.

Try this and reprt back what you discover, if you would like to send me a PM, I could give you my phone number if you need a better explanantion.............Good Luck

Hi Wrightkoss, I thought you would have had a process of elimination for me to help you troubleshoot this problem. Maybe you haven't had a chance to try this yet. Let me(us) know how it works out............Fred

How is the overheating, or are you still taking the crop off the field.Fred
