I bought a cx racing h/e and I installed it yesterday. After installing it I noticed as I'm driving my coolant temp is up around 210 as apposed to when it was stock 185. I followed one of the how to's. On the installation where I kept the stock h/e as well as the cx h/e. Someone please help me is this normal is something wrong? Thanks guys

 

Do you have a gauge for reading your coolant temps for your intercooler/heat exchanger setup ?? If not the stock coolant temps of 185 are for engine coolant not the heat exchanger. Did you route all hoses properly ?? I don't see why adding a H/E would mess with your engine coolant temps unless something is install incorrectly. Check all of your connections and make sure the hoses are routed properly.

 

That temperature has nothing to do with the heat exchangers... The tank on the driver side of the engine bay is for your engine, not your heat exchanger...

 

I did that already lol all the hoses are perfect I kno that because when I pull over and idle for a few min the coolent tep goes to 223 deg and that's when the coolent flushes through and drops the temp to 190. So I know all the hoses are running correctly. I don't have a guage to the cx h/e but the one that is standard on the car went from a normal temp of 185 to 210ish. Is my engine staying cooler? Now that I have the cx h/e

 

The heat exchanger has nothing to do with your engine, it cools the air charge that the supercharger makes.

 

So then y is my engine running hotter after adding a second h/e?

Ok I am lost now lol someone please explan what is going on to me?

 

Is the tank on the driver side filled? Is the hose that runs to the engine (left side of engine, it has an arm that connects directly to that tank on driver side) connected? Squeeze it a few times, you should hear some movement.

Basically, the heat exchanger runs water through the intake manifold, where it cools the air charge.

Adding a second one adds more coolant to the system... personally, i would remove the stock one...

You arent going to see problems unless the coolant hits well above 230. You can also make the fans turn on at a lower temperature, which would make the temps on the DIC go down.

 

Yes n yes. I don't thinnk the cx h/e is all the way filled up tho could that b a problem? And every thing was done correctly so y would my coolent temps rise 25 deg on the stock guage?

 

what ShortStack is trying to say is that the cx racing h/e you installed (if installed correctly) would have absolutely nothing to do with your engine coolant temp rising. the only thing the h/e will do (if installed correctly) is lower your intake air temp, which can be monitored with an interceptor gauge.

the intake coolant system is completely seperate from the engine coolant system.

 

Ok so then y all of a sudden did my coolent guage rise 25 deg? What would make that happen?

 

with that being said..... make sure that the coolant tank on the right hand side of the engine bay (when your standing in front of your car) is filled. also go back over your hoses and make sure you installed the h/e correctly. your engine coolant temp shouldn't be that high unless your running the **** out of it and the weather up there is 90+ degrees.

another thing to check is the thermostat.... might need to be replaced. do you still have a warranty?

 

Haha warranty went out the window awhile ago. I kno the guage is fine lol. Is it possible to install a h/e backwards? I kno the hoses are correct I would have had a big problem already if they weren't. The tank in the engine bay is full. I don't thing the cx h/e is full to the top in coolent maybe half full or so!

 

they keep telling you that the h/e has nothing to do with the engine temp ..... unless you installed a radiator house to your h/e by accident, the h/e will play no part in raising your engine coolant temps.

 

ok just stop it with the h/e.... it has nothing to do with your engine coolant temp

 

We you running the air conditioner when it was reading cooler.. and not running it when you got the hot temps?

Running the AC turns on the electric fans..

 

It is very common to mis-install the hoses, although as long as there are no leaks, it will act like it is running right.

You need to stop thinking heat exchanger....

 

Did it get hotter outside?

 

And really, as long as the temps go back down as you start driving, youll be fine.

 

Ok I live in nyc the temp doesn't change 25 deg over night. Yesterday my car was running mint n normal at 185 deg. Last nite I installed a cx h/e yes it is installed correctly im good at following directions n I check n recheck. After installing the h/e I drove to work this morn n on the highway I was at 180 deg which is normal and on the streets I was at 210ish I pulled over n watched it go up to 223 deg then it started to drop I continued drivin n it went back up again to 210ish. From yesterday to today nothing changed except the h/e. So my only guess is the h/e is eather ristrictin air flow to the rad or ac cond or stock h/e or by an act of god my car decided it wants to run at 210 deg. Eaither way this is pissing me off. So my question is how do I drop my engine temps back to 180ish or lower?

 

those all shouldnt be restricted by the addition of a h/e, because the air dam (the black plastic spoiler/lip) under the front bumper feeds air to the a/c cond, stock h/e, and radiator. if you are driving through town in stop and go traffic the engine coolant temp will go up and then go back down once the fans kick on. 223 is usually where the fans kick in to bring temps back down. On the highway you are getting unrestricted air flow due to constant movement. in town your air flow is minimized do to starts and stops.

 

Understandable except I sit in the same traffic everyday going to the same place everyday and the same time everyday. So explain to me how every day since I had this car I never went above 190 in traffic and today ironically (if that is even a word) I installed a new h/e and now I'm at 210 today?

 

can you post some pics up of your install ?? maybe we can look at it and figure it out. also, provide some shots of the engine bay.

 

Do a test... take off the HE.. if that was the problem, your coolant temps will go down..

Even so, they are NO WHERE NEAR dangerous levels, they arent something to worry about.

I would remove the STOCK h/e... and just keep the aftermarket....

 

your situation is extremely weird, i too have the cx racing h/e, but i've had absolutely no issues with my engine coolant temp. now our daily commutes are completely different so i am starting to believe that it could be the lack of air flow when your sitting in traffic.... so maybe the cx h/e is blocking air to the radiator. if i were you i'd bring this up to some of your fellow NYCers to see if any of them have had any issues.

 

I'm sticking with the air conditioner idea..
