Re: Coolant residue on the back of degas
(No puking)Theres no residue on or around the degas cap area just on the back.Looks too be some build up on the seams at the back of the bottle.Ive had this bottle for >year its a dorman plastic one had it put on before doing the heads.Do you think it might just have a hair line crack?
Could be something....could be nothing. Put a T in the line going to the degas tank and put a PSI
gauge on it. It should be around 0-8 psi
when it's hot and you have a load on it. If you are getting up around 16psi, that means your cap in venting (probably EGR
cooler leak or head gaskets). If you pressure is ok (0-8 psi
)....you could just have a bad cap that's always venting even when it's not supposed to. Maybe you are just seeing a little condensation if it's venting?
Easiest thing to try first would be to just put a new cap on it.....clean up the tank, and see if the residue comes back.
