Okay I live in phoenix and it’s hot as hell like 100f-115f. I’ve been running 210f before freeway and 225f on the freeway in the day time and sometimes at night. As soon as I get off the freeway it drops to 210f-220f. The stock temp gauge goes horizontal and the mechanical gauge says 210f-225f. the heater blows 150f on the freeway and 135f on the streets. I replaced the thermostat 180f, just replaced radiator with a aluminum radiator, replaced headgasket oem, new hoses, new cap, new coolant, bleed it correctly, new temp sending sensor, new slim line fan 2000cfm and it blowing in the correct direction. presure test it 170psi across. And I have spacer on the hood so it kinda a cowl. What next? Timing belt? Water pump?

bump

 

what does crome read?

where is your sensor reading the coolant at? is it where the stock sensor is in the head?

 

actually that's fine for a fi honda. mine reads that a lot fo the time and it's a build motor

 

ummm, i will have to ask my tuner TurboJesse. so 235f is good?

 

i don't think that's good, but i also don't know what the ecu ECT is reading and where the sensor is, say the sensor is in the head, where the gauge cluster sensor is located...well you may get false positives, because the aluminum can act like a heatsink and warm the sensor hotter than the coolant.

 

what should i do? i dont want the damn thing to blow up, like last night its not hot maybe 70 degrees out, jump on the freeway 235f, get off 210f, boost on it 4 times still 210f, jump on the freeway again 235f.

 

where is the sensor located?

what are the ECT in Crome?

 

on the head, and i dont know.

 

Where is your sensor located? From the stock sensor I read 190 after a one 5th gear pull and 195 after 2 in about 80* weather. I stay at 180 when it is colder out.

 

the sensor is in the same exact place as the oem on the head. again tonight 235f on the freeway for 10mins soon as i pull off on the streets 210f and i boosted 4 times high rpms and stayed 210f ????????????????????????????????????????????????

 

235 is not going to hurt anything, just make sure your hoses are decent. Technically 210 is perfect, 235 is hurting anything. You can try venting some of the underhood air (spacers on your hinges, take the weather stripping out of the wiper gutter) and wrapping your manifold helps too.

 

gotcha did that..... i think im gonna do a timing belt, i heard it can heat up and stretch and mess up ignition timing at high speeds, and i havent replaced it since i had the motor.

 

umm... a timing light would show if your ignition was off, by just timing the car, if your timing belt was 'stretched' you'd have more problems. Timing belts should be changed every 60k miles.

 

the guys at BAP and autozone say thats signs of the belt going bad, and i havent changed it since i had this motor.

 

235 is too damn hot.

I prefer the coolant temps in the 190-200 area, if it is constantly over 210, there may be an issue that you need to track down.

 

Headgasket?? Those were my old problems. I was also pushing out coolant too though, so i don't know. Sucks man, good luck....

 

I replaced the thermostat 3 months ago, just replaced radiator with a aluminum radiator, new hoses, new cap, new coolant, bleed it correctly, Redline water wetter, new slim line fan 2000cfm and it blowing in the correct direction. And I have spacer on the hood hinges so it kinda a cowl. What next?

 

i hope its not, i bought a Cometic .078 81mm Head gasket $100 and Arp headstuds to keep it from blowing

what your comfortable and what is safe is two different things, I have the same issue as him, its summer, my radiator is half size, I have a intercooler blocking it, and a ramhorn that works like a convection oven

 

well it stays at 235f and its at night and 210f on street even when i boost, like tonight when i spank a trans am that said he runs mid 11s i dont even think i run 12s...oh well he had his buddy and 3 girls in the back asking him" dude why did a civic just spanked you?"

 

just did a compression test and 170 across and a leakdown and nothing all good.
so is 235f bad?
this her below


She a lil dirty

 

DO you have a piece blocking the air from going in on the drivers side of the bumper... at free way speeds the air might be going on that side making it harder for the fan to pull air through..... just a though hope it helps....

 

235 is pretty high. Cars that are built generally run hotter, especially with sleeves.

Make sure you have no air bubbles in your system, and wire your fan to run all the time... see if your fan running all the time might keep it cooler.

 

ohh you cant see but theres a/c there with a slim line fan....and the radiator fan is jump to run at all times.
