new truck

[strokin94]

just bought an 84 f-250 diesel,150k, 2wd with the 6.9L backed by a 4 speed. picked it up for $750. needs a set of tires and it has a coolant leak that i just can find. also are these decent motors for pulling a trailer and general mileage.

Congrats on the new ride

these 6.9s are supposed to be alright for moving loads, just a lot slower than a newer truck. As far as fuel economy, the previous owner of mine claimed he got 20 mpg. I haven't driven my truck enough yet to give you an accurate estimate myself.

Back in the day I worked for an outfit than ran a fleet of stretched E-350 busses with the 6.9 liters in them. They certainly weren't the most powerful things on the road but they were dead reliable. If you kept oil, fuel and clean air filters in them they'd run to 400k just about every time. When we first started running them we were changing head gaskets quite often but after a while we realized that they were just weeping coolant down the back of the block and that they'd do that pretty much for ever with getting any worse. After we figured that out we'd just hose them down with brake clean every six months or so and run them.

Is yours leaving a puddle or just loosing coolant? If it's leaving a puddle roughly where is it?

This might not be it but its something to check. Sometimes the coolant reservoir can get a crack in it. Ive seen an old 6.9 that had a leak in that spot. Also I would check all of your hoses. If they look dry rotted you probably should replace them and add new clamps. If you have a chance throw up some pics of your 6.9
