i have a 99si with b16a2 swap there is a problem my temperature gauge keeps hitting the 3/4 mark does that mean anything??? does any1 know ??? if so does any1 know what the problem could be??? it doesn't overheat it just goes to the 3/4 line sometimes and goes back down

does it do it all the time? Most common problem is thermostat.

Check your lower rad hose at operating temperature. If it's cool or not really hot then your therm is stuck closed

def have this problem checked out unless you wanna deal with a blown head gasket later on.

To be safe for now untill you find out what is actually wrong, you can blast your heater witch will draw some heat away from the motor shoudl bring the IATs down. But like BB said you dont want to deal with a Blown HG trust me on that one.

Check for coolant loss. Either by leak, or burning. Coolant has a sweet smell. Keep us updated

blasting the heat will bring the ECTs (engine coolant temperature) down not the IATs (intake air temperature).
Could be air trapped in your cooling system.

thanks im gonna check it out and see if anything changes

beat me to it zeepos

As soon as the temp. gauge rises to 3/4 way you should shut the engine off. You definately do NOT want to overheat it.

Perhaps start with radiator bleeding first?

does the fan come on? if so check stat, bleed sys, it could be something simple as coolant mix make sure coolant and H2o mix is correct. most antifreeze jugs have a temp/ mix chart on the label.

andy is pwned again.

wow 3/4 is alot usually like 1.5/4 is normal temp. get that checked out asap.
