COULD DYNO PRESSURE AND HEAT HAVE WARPED AND DAMAGED THIS RADIATOR TO THIS DEGREE?
AGAIN WE ARE SURE THIS IS THE CAUSE AND FIX, SO OF COURSE WE'VE ORDERED A NEW RADIATOR $$$$
WE THOUGHT EACH PART WE REPLACED WAS THE CAUSE AND FIX. IT WASNT.
First thing- if ever you are "uncomfortable" about a service person's expertise, qualifications, or attitude- PULL THE PLUG!!! Don't
wait to see if all will be fine- usually your gut instinct is accurate, IMHO.
That said, the damage is done. So, I will ask this- was the "dyno" (chassis dyno?) equipped w/a large- preferably ducted- fan to cool the engine/tranny while the runs were conducted?
That the coolant was forcibly expelled from the cooling system, there was overheating- for whatever reason.
Could have been a bad thermostat, for that matter. But w/o air flowing to cool the engine while under load, all bets are OFF!
And, the tranny shouldn't have been in OD for testing. IMO, it's better to test in a lower gear, besides, most trannys don't have a lot of holding power in OD.
BTW, what is "capped"?
