Horrible overheating issue

[Polrber244]

Hello TVT!!! Thanks for what everyone does to help keep our vans rollin.

Ok...I replaced fan clutch, t-stat, and water pump with all OEM parts yet my van still overheats with 6-8 miles of driving. Idling in my driveway the van's temp needle will hover around 50%. If I take the van out for a drive, I am lucky to get 8 miles before the van hits about 85% on the temp needle. The overflow container begins to violently bubble so loud I can hear it before popping the hood.

I am starting to wonder if Im having a partial HG failure that shows itself once the van gets hot (expands) showing holes that are non-existant at lower temps or if the extra comprssion from accelerating is pushing the compression gases into my water jackets.I have seen none of the typical signs of a full blown HG but Im lost as to what else to do with my Yota Beast.

Any insight would be wonderful. Thanks.

Im gettin a beer to help with my brainstormin and mostly my sanity
