My 95 e350 7.5 gas cutaway has been overheating and thought I get some advice here. When it sits at idle it wouldn't overheat but when you drive it for 30 minutes or so till it warms up, the coolant gauge shows it creeping to hot and once it does get too hot, coolant would boil out of the rad cap.

So far, I've changed the thermostat, waterpump, and belts. Any other idea? I heard someone said something online about the fan clutch being bad but it looks like this van does have a fan clutch but it's not electronic and belt driven? but I could wrong because the fan is spinning once I start up the car.

 

Check your radiator

 

What should I be looking for? I look the other day and no leaks.

 

Try spinning the fan cold, engine off (of course). There should be resistance and it should not spin easily. Start it up and bring the coolant up to temp. Shut it off and try spinning again. It should be harder to spin hot. The clutch is in the hub and temperature controlled.

When it overheats, are you in town or on the highway? In town, slow speed should be the worst, at speed on the highway, the fan isn't needed much. jim

 

I'll try that tomorrow, it overheats once im off the highway.

 

Here's a helpful link.

Good luck.

 

Had very similar problems with our 1993 E150 and the radiator was clogged up and bottom fell off when it was unbolted

 

Is the coolant level low?
Easy to miss the obvious

 

I haven't seen this on vans too much but another thing to check is crap getting stuck between the AC condenser and the radiator.
I've see potato chip bags, paper cups, leaves etc. stuck in there.
I also believe in checking the simple stuff first.
