What radiator options??

[Limo]

Hi, my car has been overheating the past couple of days, in that time I have replaced thermo fan, flushed coolant and checked all connections. It had stopped overheating in town and was going fine, until on my way to work this morning I found the car OVERHEATING!! on the highway! WTF!!! Highway = high flowing air into radiator = how the hell does it overheat, isn't it supposed to overheat in town.

Take it to my mechanic looks at it and sees that the top coolant hose, is bulging and says to me there is alot of pressure and says the reason my car is overheating could be because of lack of flow. Therefore he tells me my radiator might be blocked and might need to be fixed/replaced. He was also telling me the radiator I have is "too small" and might have to consider for a full size radiator.

i had this prob with my crx a while back, when it got real hot, the hoses would bulge/expand.i also changed themostat, flushed oem coolant and got my radiator cleaned and pressure tested all didnt fix the prob.
then when i changed over the hoses and everything has been fine for over a year now.

Ok, I took the radiator today cleaned it and looked for blockages and found none. I then put it back in a put coolant in blah blah and released the air and took it for a drive. It still overheats on the highway.

I know need to start eliminating causes.

Thermostat - thermo fan switches on and car is cool intown driving so no
Radiator- Just cleaned and checked it, couldn't find any issues so no

My next guess is water pump.

What else could it be?

Ok, took my radiator in this morning and its blocked.

Guy wanted $350 to fix, sooo I am looking for a new half size radiator.

Is a civic B16 radiator useable with a B18 Integra as I am finding alot more for the civic.

Also where would I be able to get one of these bad boys.

I don't want too cheap out on a radiator because I know getting a cheap one now will make me replace it soon anyways

Half size radiator for DC2 Wanted! HELP!

OMG legend!

Do you remember how much it set you back at all?

That would be very helpful.

Im guessing something like this is too shit to use right? http://cgi.ebay.com.au/Aluminum-Radi...item27ae57afa7

My car overheats on Honda OEM coolant as its too thick for an aluminium radiator!!!

Changed to Castrol post mix and mix 30% coolant 70% Water

Problem solved

good point.

For example - standard honda cars that come with NO aircon ( breeze for example) actually come with a block off plate to divert more air to the radiator for maximum efficiency

This is also what my Tuner told me to do for even better cooling

can't rem, but best to give Hakan there a call he can organise one for you. Pretty sure its less than the $350 you'd have to pay!
I've been using mine for 2 yrs now no issues

OMG legend!

Weird thing is it wasn't overheating before. I flushed my radiator and using Nulon concentrate to 30% diluted and it started overheating.

You reckon using a different coolant or diluting it more to like 20-25% would make it less likely to overheat.

Thing is it was not overheating before??

Hmm this might be something to do before buying a new rad

check your hoses when it get hot. are they both hot? is one hot etc there are only a few things that can make your car overheat and cooling is usually not one of them.

fans not engaging- do your thermos come on and go off..does your overheated car cool down in this time?

radiator bloackage- as discussed before, also it happens alot so dont rule it out

hoses- blocked/clogged with scale and other cooling system contaminants. or leaking hoses can be an issue also. is your car using coolant?

thermostat- if your top hose is hot and bottom is cold then generally your thermostat is gone

cracked head/gasket- if your car has boiled over and cracked the head or gasket then you may have rectified the first overheating problem but now are dealing with a much larger problem. have a mechanic do a headcheck on your car. they generally wont charge for this.

diluting coolant is not the answer to anybodies problem coolant is supposed to be 50-50 mixed. i reccomend oem coolant because its pretty and blue. but seriously manufacturers in most cases advise that you dont change coolant for the first 100,000 obviously the stuff they use isnt shit

above say the radiator place told him the radiator is blocked
