Would anyhting happen to my truck if I drive with a bad egr cooler for a little while until I get the new one installed?

 

you could damage a rod if it hydrolocks and it probably means you have a bad oil cooler

 

Park it, its not worth taking the chance of the added damage

 

How bad is it? How hot does it get? If you didn't read this forum, would you have known you have a problem? How long do you need to drive it? A day-a week - a month?

 

If you have a bad/leaking EGR cooler the antifreeze is being drawn into the intake manifold and the engine cylinders. Since antifreeze does not compress you can get high cylinder pressures that will stretch head bolts, causing leaking head gaskets, bend connecting rods, etc.

Mine failed a 1/4 mile from home and I drove home very slowly. Afterwards I thought I should have released the cooling system cap to relieve pressure on the cooler but the engine was still cold so I think I got lucky.
