RE: [Chrysler300] Loss of coolant

[christopher beilby <thelastbestgenius@xxxxxxxxxxx>]

1) Troy is right that DO NOT RELY ON YOUR TEMPERATURE GUAGE if you lose your coolant, by freeze plug popping otr whatever. My dad's old Healey that recently blew a plug on it's first good drive after somebody else (professional restorers) installing them HAS IT'S TEMP SENDER/PICKUP in the radiator top tank - so does my 70s Lamborghini I think - so they for sure will register 'cold' right up til motor melts if water gone.

2) Re others talking about copper and stainless modern alternatives, just days before all this latest 'core plug debate', after my house taphead  'corroding off' a copper pipe, I had asked my plumber if brass was first used in core plugs as replacement for original steel factory ones because it was inert, unlike copper (as in my tap pipe), and he said yes brass is passive re being put in cast iron blocks. Stainless and copper I do not know, but can ask. Copper for sure is not, and it way softer than brass, so maybe they could blow unless made thicker?!

3) Where are our '300 Club Member' 1950s-60s Chrysler Factory Engineers on this core plug subject - don't we have some who worked there when these cars were built - what can they or other Mopar Lists add to our knowledge/questions?  Many 300 Members are likely sick of this topic, so if we can put it away as fully solved, say on the Club Main Site, then it will see this topic more 'offlist' in future, except for quick advice where to access the topic on Club Tech page ??!

In the many thousands of $$$$dollars, untold hours etc, it costs to get a 300 back on the road - restored - this core plug one is the biggest single simplest least cost item thing any 300 user wants to get right, plus know it right. Otherwise you can ruin a 300 hemi or ram engine in just minutes, never mind the cos$$$st and woes fixing it. So better to get it right if we can for all , never mind ourselves??!

Subject: [Chrysler300] Loss of coolant

  



I once lost all coolant in a '64 Plymouth while it was sitting. After I 
started the car, (it was mid Winter), I started driving and waiting for my 
heater to do its thing! I never got any heat and kept noticing that the 
temperature gauge would not "climb". So, keep this in mind; a gauge will not 
register if there is NO coolant flowing around the temperature sensor, no 
matter how hot the engine gets!!! I assume all engine temp sensors work that 
way???
