Well i just wanted to make sure my car ran nice and cool cause i drive a lot of "stop and go (real fast)" and sometimes the temps creep up twards the 3rd mark and i just wanted to make sure it ran cool...
ive heard people on here say 160 is ok, but my friend says the aluminum and steel wont warm up right together when the water comes in at such an early stage... ur opinions plz

 

Many people on here, including myself, have used the 160* for a long time thermostat with no problems. Getting a manual fan switch, or getting your PCM tuned to have your fans come on sooner would also help. Keeping the temps down is good for the LT1s.

 

ok i bought 1, $3.99 donno if there is any difference in brand, but how do i install it, i have this guide but its not always very good at describing things

 

If you bought one for $3.99, you got the wrong one. It needs to look like this (long style) to work properly in the reverse flow cooling system the LT1 has. Expect to pay $16-$20 for one.

If you search, you will find lots of threads about the 160º thermostat.

Changing thermostat

More cooling system info (including some talk near the end about the 160º thermostat).

 

yes, mine cost $21 for the hypertech one.

 

hrmm i got it at autozone, and the lady got it for me, she looked up on her little computer, both the 180 and the 160 were 3.99

 

A search would also show you that AZ is famous for handing out the wrong thermostats. Their computer database is just plain wrong. Other people have said that they were able to buy a Hypertech thermostat from AZ from sales people that knew what they had.

 

YES, they gave me the wrong one the 1st time

 

k i'll goto pepboys

 

never trust az's parts unless you see them first. I waited for 1/2 hour for them to find me an injector that was the wrong one. they also do not understand the idea of a long tailed thermostat. They said that the newer designed thermostats do not have the tail. Even though this tail is very important to the reverse flow engins. They are very incompetent unless you know what you are there for or you might have a good sales person. But I would never trust there advice.

 

Don't shop there. Here's why.

I wouldn't buy ANY performace part from a retail store.
