Well I haven't been on here much lately, which usually is a good sign nothing bad is going on. Just recently towed my fifth wheel up to the mountains and lately I have been noticing a little antifreeze smell around the engine bay of the truck. I haven't been able to find any noticeable leaks so now I am wondering what else may be going on. I don't think its head gaskets because there is no abnormal smoke discoloration but am wondering about the symptoms of injector cup problems. Any information would be very helpful and also anything else it might possibly be. Thanks for all the help.

 

Do a pressure test on the system and look for leaks

 

Ok what is the best way to do a pressure test? I have never done one before but last weekend I did a hard pull with my fifth wheel and when I got done I didn't notice it leaking anywhere. The truck was good and warm after that and I figured after a hard pull like that I should be able to notice a leak.

 

Check your thermostat housing they tend to leak with out leaving a trace of coolant.

 

With a coolant system pressure tester. You can rent them at autozoo

 

Ok is there anything else that I should look for. Does anyone know what the symptoms are of bad injector cups. I am really hoping that's not it. I will look into the pressure tester.

 

Look under the water pump at the weep hole. 5$ to a fat mans a$$ the water pump is about to crap out on you.

 

No I hadn't thought about that. I replaced it probably 2 years ago and don't drive the truck all that much. I did get stuck buying a napa special though.

 

My truck smells like coolant from time to time, this has been since I bought it. Like you I was alarmed and interested but after a while of watching the level in the degas bottle it's never dropped. On to greener pastures...
