Howdy all. Made a smart purchase at auction (didn't read description because I was under the reserve: Ha- they lifted the reserve and I got it - cheap but,...).
Was told it overheats and needed new head gasket. Did a test on the radiator with check fluid. It stayed blue (3 tries). Changed oil, no froth or bubbles there. No steam or smoke from tail pipe.
It runs cold for a while then temp spikes, then drops quickly, then repeats until it overheats. Stays cold at idle, only overheats under load. Funny in that it blows the top off the overflow reservoir and blows steam and water. Seems like I'm getting air in from somewhere and loosing coolant. Replaced thermostat and also ran without one, flushed radiator and engine until water ran clear.
I'm stumped. Maybe the head gasket is blown? It is a diesel.
