Re: Water pump woes?

["jtrealtywebspannet" <jtrealty@xxxx>]

IMHO what starts this sequence of events are small leaks on top of the 
motor from the distribution pipe and-or the hoses off the back of the 
water pump. When the owner eventually lets the level get too low air 
gets into the system and is never properly bled out. The way to avoid 
this is to replace all hoses and seals. The continuous bleeder is a 
good idea but really isn't required on a car that has a tight system 
with no leaks. It can be done but it requires a lot of work to make 
the system completly tight. Another little thing I have done (but not 
on Deloreans) is to drill a small (1/8) hole in the plate of the 
thermostat so it can pass air. This helps on other cars so it might 
work on Deloreans but I have never needed to do it as on a tight 
system once you bleed it it doesn't have any air inside to pass. If 
you are still driving on origional hoses and water pump then you are 
just asking for trouble, never mind about a little air. For any owners 
who have to add coolant be warned that this is a signal of a serious 
problem. You will never see the lost coolant on the floor because of 
the way the leaks leave it on top of the motor to evaporate.
