Coolant Pressure. Help!!!

[fiffer]

Here we go again. Is there anything that could cause coolant to blow out the degas bottle besides head gaskets. I just did head gaskets 15000 miles ago as preventive maintenance. Since I've owned the truck before and after gaskets I've had a coolant issue but never tried to get to the bottom of it until now. My mechanic seems to think its a cracked head or blown gaskets but the heads were remanufactured and the gaskets were new. I also did an EGR delete and my oil cooler is not clogged. Any other ideas? Also, I think I'm in need of new diesel mechanic in the south central Pa or Hagerstown Md area.


Thanks,
Chris

First thing I would do is replace the cap. What head gaskets did you use when you redid them?

Ford Gaskets and yes we replaced the cap. I'm reluctant to think it is gaskets because they were just done and this issue was before and after gaskets.

Have you monitored your ECT and EOT while driving it? If so what are they reading?

[fiffer]

Edge CTS... temps read 192-193 but do creep up if i run it a little usually to 198-202 ish. If I go up the mountain even in cold weather it gets warm fast. Over 210 even if its 32 out. During the summer it will overheat if I don't drop it into 3 to keep the rpms up of the fan. Could be because of the coolant it pushed out?

[dhanna6powerstroke]

That's your coolant temp. What does oil temp show? There should be no more than 15° difference. You need to compare the two while driving unloaded on flat ground at 65 mph.

Your running hot. Like dhanna6powerstroke said if your EOT/ECT temperature split is over 15 deg your oil cooler is restricted and needs replace. Also check your thermostat, water pump (impeller's crack at the pump shaft) and your clutch fan operation. Do you get any codes for the fan? I always install snow plow clutch fans on 6.0 trucks it makes them run alittle cooler. They will run between 188-195 deg depending on outside temperture.

[fiffer]

That is both temps. They are very close together on flat ground running at 65mph.

No codes. Oil cooler is fine per the delta rule. I know I'm running hot. Thats the issue I took it to the shop for. I'm asking what can make the coolant blow out the cap because I think my heads and gaskets are fine. All help is appreciated fellas.

Also, the thermostat was just replaced and I am running a diesel site coolant filter.
