my 82 turbo 245 is having some problems. last week a hole developed in a coolant hose right before it enters the engine (it was the one directly under the intake). i went and replaced it with a nearly identical hose from napa, refilled with the type c 50/50 coolant. everything worked fine until today. it was a pretty warm day today in portland, was returning from the airport. there was no signs of overheating, all the gauges were fine, running perfect etc. i got home and went in the house for a moment, then came back out to find a ton of coolant running down the gutter. i popped the hood and found the green stuff spurting out from under the cap of the coolant reservour. it seemed to be really hot. after it stopped, the resivour was totally empty. so i'm scratching my head tryin to figure out whats wrong. i'm a little worried that this and the incident last week are a sign of a really big problem. i was wondering if maybe the cap just wasn't on snug enough, or i f'ed something up putting the replacement hose on. any insight would be awesome. thanks as always.
