ok i just slapped on an edelbrock rmp upper and lower along with 1.6 roller rockers and a new cam this weekend. car runns real strong and on the freeway this morning my temp was running at about 190-195deg then i got on it on the freeway and my temp kept jumping really fast from 190 to 250 and kept jumping back and forth. anybody know why its doing this?

on another note... when i took my stock manifold off it had no t-stat in it what so ever... is it ok to run no t-stat during these colder months?

 

If u feel like freezin ur azz off its fine sounds too me that u didnt put the mainifold on right theres a pattern u tighten the bolts in also i might be leakin coolant somewhere check everything ifu smell a sweet smell then u know its that.Do a process of elimination.How ya think must of us know what we know we went threw this.

 

No, it's not ok to run without a thermostat. You need it to control engine temp, especially in the colder months.

 

did u put the stat in right? its easy to mess up thats y I ask.

 

Air pocket in cooling system, bad thermostat ot a partially clogged radiator.

Did you burp all of the air out of the system before replacing the radiator cap?
