[Healeys] Subject: Re: alum radiator swap

[i erbs]

so the idle stall at 190+ temp could be vapor lock?? I missed the obvious
while troubleshooting. My car started running hot 192  and then above while
driving on the freeway in 90 heat . or it would spritz water out around the
radiator cap. I replaced it twice. might be a crack in one of the welds.  I
am going to take my oem unit to a radiator shop to have then pressure check
it.
