turbo-civic keep overheating.
 

ok..i been having my civic ex coupe turbocharge for about 2 month now i think not sure..tho, but anyway lately my car been overheating real easy..and most of the time i was driving normal not even going past 5000 rpm , and also when i am boosting i could get about 3 good runs before the car temp gauge goes up to hot real fast. just wanted to know if anyone else have this problem, and do i need a bigger radiator or what? oh yeah and im useing my stock one right now.

Re:turbo-civic keep overheating.
 

I say change the thermostat since its cheap and take your radiator to the shop and have them make it double core.

Re:turbo-civic keep overheating.
 

i say check if ur fan turns on, cheaper and less time consum :Ping

Re:turbo-civic keep overheating.
 

im gonna say u blew your headgasket...my car would be okay then after a 30 min drive as im just rolling into town or so. or stop n go traffic. my ---- starts to get hot. if your overflow tank is full. im gonna bet its your head gasket

Re:turbo-civic keep overheating.
 

if it is the head gasket I beleive the oil would look like cement cause the oil would mix with the anti freeze.atleast thats what happened to me >:(

Re:turbo-civic keep overheating.
 

yeah, i think it might be the head gasket im gonna change change it and see what happen. thankz alots ed , and also i fill up my coolant tank every week or 1 n half week or so . is this normal?

Re:turbo-civic keep overheating.
 

thermostat, radiator flush, fan switch temp sensor, i did all three after i boosted and it was the fan switch temp sensor you can buy different ones like ones that turn or sooner than others so the cooling system works more.

Re:turbo-civic keep overheating.
 

If your headgasket is blown, it wont necesarliy mean your oil will look like cement. The boost could be going into the cooling system therefore pressurizing it. Happened to me once. It has nothign to do with the oil, if I could upload a pic of my old HG id show you, all 4 fire rings (i think thats what theyre called) leaked through into the coolant passages. I had a felpro on there, so I got the head machined and bout a KP ($20 cheaper) that was made by Altrom. Also put new head bolts as my old ones I reused for the 4th time. It sees 10 psi of daily boost and not once does it even think about blowing again.

Re:turbo-civic keep overheating.
 

You might want to try a few things first:

1. Check for external leaks.

2. Make sure your fan is turning on.

3. Make sure your thermostat works (top and bottom radiator hoses should get hot after awhile).

4. Check your oil for coolant.

5. Free fixes: Purge the air pockets out of your cooling system.

6. Cheap fixes: Flush and refill the cooling system, replace radiator cap and thermostat.

7. More expensive fixes: Water pump, radiator

8. Maybe it's your headgasket?

9. You're fucked. Deal with it.

Re:turbo-civic keep overheating.
 

yup, deal with the problem and get it over with.

Re:turbo-civic keep overheating.
 

NOT normal.

Re:turbo-civic keep overheating.
 

my car does the same thing.i can start it up and get on it going around the block and it starts heating up.must be my h/g too. i just bought this h/g off ebay and installed after my valves and ---- was put in. :'(

Re:turbo-civic keep overheating.
 

oh...do not use cheap walmart supertech oil. i thought my hg was blown, did a compression check and it's fine. 90-first comp stroke 210 7th comp stroke across all 4 cyl. b16. last night i added restore oil additive and it doesn't overheat anymore, it must've made the oil more heat resistant. mine would heat up after 7 or 8 hard runs and then cool down if i laid off the boost. after adding the restore, no more heat ups, i sound like a comercial. seriously though, i had synthetic oil before 2 weeks ago and no problems. tommorow i'm putting in some synthetic mobil1 :P

------- A.

Why is everyone so quick to just up and replace their headgaskets? ???

Re:turbo-civic keep overheating.
 

w3rd! do a compression test. mine overheated after a few hard runs and then would come back to normal if i drove normal (slow not too much boost) i added some oil additive-restore- and it stopped. i had used cheap .88 motor oil on my last oil change and that was the cause. comp was awsome on all 4 cyl. i was thinking it was the hg/rings-synthetic oil own3z me

Re:turbo-civic keep overheating.
 

It's probably not a bad idea on a boosted engine at some point in time, but me and another guy in town were both having heat problems a few months ago (he's supercharged, I'm turbocharged). I was going bit by bit and he just up and replaced his HG and he's trying to convince me to do the same.

After he does his, he calls me up all frantic, saying it didn't work and he thinks he warped his head and when I replace mine, I should definitely have my head milled. He knows a guy who will do it for me (when I do mine) for cheap.

End of story, I have no idea what his problem ended up being, but mine was probably a mix of air pockets and a bad water pump. I have new head studs waiting to go in, but I'll do it when I'm good and ready... ;)

Re:turbo-civic keep overheating.
 

yea my gsr is boosted and mines jus recently started to over heat....i just thought is was my thermostat since it fluctuates right??...hhmm my frends thinks it is to since it happend to his car n he sed it was the thermostat...im fixin that first how will i kno if its the headgasket?? i jus bought a new radiator but its oem replacement all metal..and my revoir is like at normal level at all times....

Re:turbo-civic keep overheating.
 

You can tell it's your thermostat if one of your inlet/outlet hoses isn't getting hot... Meaning, the car's getting hot, your coolant is getting hot, but the thermostat isn't opening to recirculate the "cooler" coolant from the radiator (or vice-versa) and that's making your engine hotter. Mine would get hot and then cool off (a little) when I drive. Fucked up. :-\

Other cheap fixes (and not bad ideas) would be to flush your system (or have it flushed) and get a new radiator cap. From there, you can bleed the system and make sure you get all the air out.

If all that don't work, you're looking at a water pump or new headgasket. I guess a compression test or seeing oil in your coolant (or coolant in your oil?) would tell you if the headgasket is bad.

That's about as far as I've ever had to go, but I guess a bad or damaged block isn't totally out of the question. A fucked up or leaking radiator too.

Re:turbo-civic keep overheating.
 

i wired my fan up to a switch, just hacking into the harness. i set it up so both my a/c condensor fan and the radiator fan come on at the same time, both hooked into the radiator fan switch. then ran that to an external switch, so i can switch my fans on whenever i want to, but it still comes on automatically when the coolant temps get high. its really useful for when ur at the strip and want to cool down between runs. i also usually switch it on in stop and go traffic. i'd rather wear out a fan faster and get a replacement from a junkyard than shorten my engine's life. A little $20 fan is a lot easier on the wallet than a $500+ rebuild.

Re:turbo-civic keep overheating.
 

Im not boosted yet but I had overheating problems. One day driving through town the temp gauge shot straight up so I tried to get home ASAP. But of course, while steam is rolling off the front of my car, there has to be the most traffic. So Im sitting waiting to pull out, and notice everyone starting at me (or my car) but I dont care and just want to get home. When I finally get there, I get out, walk to the front, see the steam rolling from the hood and bumper, and then see a stream of coolant spraying straight out in front of the car. So thats what everyone was looking at :o

I have since ordered and installed a dual core, and I havent overheated since. :)

Re:turbo-civic keep overheating.
 

In my 90 integra i have a new dual core 92-95 civic radiator,new thermostat,nearly new headgasket and i took my waterpump off and inspected it to see if it was fucked but it spun freely and i see no coolant around the weep holes.and it still overheats. :-\

Re:turbo-civic keep overheating.
 

ok..i change my thermostat yesterday which i found out it was bad so i change it then i drove it a few time around my block real hard which it didnt over heat at all so i thought i fix the problem but today while i was driving to the store it started overheating again and i wasnt even boosting, i was driving for about 30 min. ok now im thinking of adding the oil additive-restore ---- and mayb check my water pump , n also i change my oil before i put a new thermostat and i didnt see no coolant in it, so does this mean its not the head gasket?
