Coolant disaperaing

[jonnysteals]

In the last 10,000 miles new egr cooler oil cooler, deguass bottle and fuel pressure regulator. Mine recently loosing coolant and it pukes when I tow pretty good. Stock tuning no tuner here. I was about a gallon low last month and am gonna go put another 1/4 gallon in it tommorow. I noticed my fuel mileage dropping too. You think its the egr cooler again even though it was literally replaced like 10,000 miles ago. I have a a set of studs ready to go in. Thanks for the help


Forgot to mention when they did all the work to it they pressure tested it and said heads were good. This was prolly 6 months ago and 10,000 miles. Also new turbo(stock) was done but Iknow it has no bearing on my current condition but figured I just add that in there.

Open your oil drain plug a little and see if coolant comes out.

I pulled my dipstick and the oil did not look milky and was not overful. Id rather not pull my drainplug becasue I just changed my oil like 1000 miles ago and dont want to try and drain a little oil. Any other place to look?

You need.... Fumoto

I need headstuds and an egr delete not a fancy little drain valve lol. I read somewhere about a egr cooler that had a little crack in it that would only leak when warm. I dont see any coolant leaking could this be somethign I can look for????


Any suggestions would be great??

You wouldn't have to drain it at all. Just crack open the drain plug slightly and if there is any antifreeze it it, it will come out before any oil will so you will loose no oil.

Is it bowling over? Is the truck getting hotter then normal? and if the egr cooler was leaking realy bad you would be smoking.

before replacing hg's I would run combustion gas leak test on it first. You can get tester/fluid for about 50 bucks. Easy to tell if it's EGR/HG's with this test.

I had a combustion gas leak test run yesterday on my truck - it too is puking large amounts of coolant under a loaded tow - in the last 2 days I have put in 5 gallons of coolant. The combustion gas leak test rang a definite negative! It was negative for a gas leak. I had a new thermostat installed today and it still is puking coolant. So what now?

Think I found my problem. at 80- mph my bottom radiator hose blew off and drained all my coolant. I think the clamp been leaking under pressure for a while. Cover my truck in coolant and kicked the back end of my truck sideways. It was sketchy but we fixed it on the side of the road.
