[SHOtimes] heater core and helms manual

[Stephen Weinrich]

There is still a pretty good chance that the problem is just the hose-to-core connection.  An inspection mirror and a flashlight are the correct tools to use to find out.
 
If you need it, there is a complete set of heater core replacement instructions at Dennis Wolfe's site.  I have the address at home and can pass it on later this weekend if you actually need it.

Hey all,

The '93 I sold has aparrently developed a leak on the firewall side again. 
Last summer, one of my heater hoses blew and I replaced both of the upper 
hoses. On the drive back home, while testing the A/C, steam shot through the 
defrost and vents and I thought the heater core had gone south. While having 
the car checked out, we took a good look at the hose clamps and saw coolant 
leaking from the connection---tightened the clamps down real good and 
problem solved. The car's coolant was also flushed.

The current owner (who is a pretty nice guy) and I chat occasionally and he 
tells me that he had the car pressure tested and it is leaking down the 
firewall side and soaking the insulation. I'd like to help him out a little 
because I thought this problem had been resolved---maybe even (gulp) help 
him change the heater core. So, I'm looking for a Helms manual for a '93, 
maybe even an EVTM as well.

Also, if there are any other culprits that would cause the firewall and 
insulation to become soaked with coolant, I would love to know about them. 
The interior and carpeting is still dry as I understand it.

Thanks,
Dave
