I got a 2006 king ranch, it's burping coolant and I can smell coolant after long drives. I did a coolant flush a few months ago, changed the degas cap, and cleaned the EGR valve. The truck runs great, no over heating, smoking, or signs of coolant in engine oil. I'm sure the truck has some kind of tuner because it gets awesome fuel mileage. I'm praying it's nothing serious. Any suggestions?

 

Sounds like you need new head gaskets.

 

pull the egr valve and see if it is wet with coolant or if there is a puddle of coolant in the intake,if so the it is a ruptured egr cooler but you will normally get steam out the exhaust when this happens,,,,,,head gaskets are a strong possability

 

Mine was puking coolant when my oil cooler started to clog up. Hard accelerations or high temps for other reasons cause high pressures in the system and cause it to puke coolant too.

 

I just serviced the truck, I bought the a new degas cap from the dealer and its alot better. I dont smell coolant or see it dripping like I use to. There is a small amount around the cap after long drives up hill or towing.

 

99% chance your gaskets are blown. do a coolant pressure test on it and see what you get

 

I am going to try that next. I hope and pray its not the Head Gaskets! Best case scenario the pressure is good, whats next? Oh and btw my check engine light came on and the #2 glow plug is out, got a new plug but whats the best way to remove the plug?

 

I doubt the pressure will be good if youre still getting coolant pushed out under load. You can go through the inner fender to replace the glow plugs. The harnesses can be a pain, usually I do the entire bank and have a new harness on standby.
