[Tigers] Lower Hose Spring is Required

[Carmods at aol.com]

This  is a repeat of a tech tip is send in about a year and a half ago.  
A  spring in the lower hose is defiantly required. If a car suddenly 
overheats  as the rpm goes up with vehicle speed, the problem is probably caused 
by  the collapsing of the lower hose when the pump inlet pressure goes  
negative. 
For  some reason, some hose suppliers have quit supplying the springs in 
lower hoses,  probably some low cost un-American supplier. I  found that a  
"Rainbird/Toro"  impulse lawn sprinkler has a stainless spring that works  
great. The spring can be twisted if necessary to make it  tight. You can buy a 
sprinkler head for about $16.00 and it's worth it just  to find a stainless 
spring.
