coolaint puking

[Lancer250]

Took the truck in for coolaint puking out of the degas bottle. Service rep called me and said they found a thermostat stuck open and that caused it to puke. Does this sound right?

That sounds wrong!
A stuck open thermostat will allow coolant through at all times. That should only affect the coolant temp which will be colder then needed...
Makes no sense at all to me.


Coolant bottle cap, EGR cooler, or Head Gaskets!

When you get it back, run it hard and check for puking ASAP, that way you can take it back to them as soon as you can and tell them they are wrong!

I told him that didn't sound right and the temps have all been good. He sounded kind of stumped and said they would replace the thermostat and continue testing

Puking degas could be blown head gasket worst case scenario

They decided it was HG. They will put ARP studs in when they do the HG. What are the real benifits of going with the ARP studs?

this not happening again...

When the degas bottle pukes its a 99% chance it's the head gaskets.

Stronger than stock and wont stretch allowing another blow HG.

Also make sure when they do the gaskets they magnaflux and deck the heads. If they dont want to its worth your while to pay to have it done.
