[Healeys] Subject: Re: alum radiator swap

[Richard Collins]

In my humble view 190 isn’t an issue: except as in my case I get a vapor lock so fuel starvation is the issue. But at highway speeds, 180 is the norm. Stop lights get me to 190’s and vapor lock ( in the summer) not so much other times.
After 20 minutes of cooling, I can go again.
Mine is ORM radiator and 4 blade fan;  new water pump and fan shroad

Thought I'd share my experience with the alum radiator.
First I had the OEM radiator boiled cleaned etc..  Then I put in a flex fan.  Finally a 160 degree F thermostat.
    Results: Helped a bit but in the summer and in the desert the temp went to almost 190F.

Talked to someone who had an alum. in his MGTD.  Said it gave him 20% increase in cooling.  So being foolish I bought one.
    Results:  Absolutely NO change.  Well it lightened my pocket book.

Recently talked to a man who made a shroud for his healey and claimed it made a big difference alng with his Texas Fan (6 bladed).
     Results:  I started to make the shroud BUT.  The fan is not centered on the radiator.   The fan is 1 inch to the left of the radiator.  So the plans for a shroud isn't going to work as is.

      Questions:  Is the motor incorrectly mounted causing the offset?
                        If I put in an electric fan is it best to remove the flex fan completely?
                        Would a four core radiator be of any help?
                        Should I ignore my fear and let the temp go to 190F without a worry?
I live in the desert and have to go over a 5000 foot mountain to get to Las Vegas.
Thanks..............    Al
