So after working on my car a little I took it for a spin and the temperature gauge went all the way down to cool, I noticed an exaust leak, and my radiator fan won't turn on. This all happend at once, when I hit a bump, are they related? where is the sensor for the gauge?

no ideas?

ok I found the temp sensor, apparently my cooling system is really efficient, after idling my car in the driveway to half way up the meter, it only took less than a 1/4mile to bring it all the way down hmmmm

 

the exaust leak on the other hand is completly different and probably encouraged by the offroading I did the day before , so I'm lucky I have plans to pick up a free WRX exaust this weekend that I plan on mating up to the '79 :-p if that doesn't work then I'll just go with a high flow turbo muffler, before the rallycross on the 30th

"it only took less than a 1/4mile to bring it all the way down hmmmm"

 

 

this my friend is an indicator of a

missing thermostat

or

one that is stuck open

 

I would look into it as.

 

It could lead to hesitation as the engine is running too cold

but

I'd test the vacuum advance on the distributor

I posted a while ago on a temp guage problem. I lost a heater core hose a while ago. I had to limp it home. After I changed the hose out the guage takes along time to show any heat. Some one else thought I might have air left in the system. I am going to check out thr thermostat. Will let you know. dp.PS. How would the vacumn advance affect the temp guage?

Dave, this is kind of a follow

up thread to the post "A Simple Problem"

 

I was merging ideas on the hesitation he has and the engine temp

 

but wanted to throw in the vac advance. as another possibility
