Coolant question?

[rksorrells]

I discovered I have a small coolant leak. On the front of the motor just above the lower large rubber radiator hose is a small metal tube that comes out of the block and turn upwards and to the right (please forgive my lack of technical knowledge). Coolant appears to be leaking from where this tube goes into the block. I plan on taking my truck in to have the EGR delete done and if this is not part of that, I was going to ask them to fix it. The question I have is this. There is absolutely no coolant in the plastic bottle on top of the engine, however my temp gauges never go above the halfway mark. The last time I checked the coolant levels was about a month ago. I discovered this leak when I was trying to figure out why my heater would blow cold air. Since my gauges are not reading out of the norm and my truck is not showing any signs of overheating, can I continue to drive it for a couple of weeks till I can get it into the shop? I just drive about 30 miles a day and I am real easy on the truck (trying to get good MPG). Any ideas? Thanks

I personally would not drive the truck with it low on coolant. Cavitation happens very fast. I would keep adding coolant or distilled water until you can have it fixed.

What is cavitation ?

[rksorrells]

Looked up cavitation. Sounds horrible. Don't want to risk that. Anyone know if the metal tube I described is part if the EGR cooling system?

Like 04hdfatboy's said, isn't good idea running it with low coolant. If you don't want to buy a gallon of coolant (I don't blame you... economy suck nowadays) at least add distilled water until you fix the leak.

It does sound like the part you are describing is the flex part of the egr cooler.
