"Trimming" the bumper will help with coolant temps. I had an overheating issue and found that the intercooler was pretty much sealing the main inlet for air. I did'nt want to cut the grill out completely so I trimmed the grill from the inside (if that makes sense) which gapped the intercooler from the bumper which helped. Hope this helps

wow thanks for all the replies guys. Im still waiting on my cooling plate to come in and im gettings my car tuned in 2 days which should help with my running lean... I also turned my fan on all the time which did get my temps under 200 around town. im now hovering at about 197 which is acceptable to me for now. Once im pushing alot of boost im sure that will change, so im going to start looking into modifying my bumper and blocking off the open side as suggested. Ill keep this thread updated with my results as i make more changes.

Thanks again for all the suggestions

Wish you the best an take care.

Having the same problem with my setup I will check you thread for update

That, is awesome. I paid over $130 for a shroud.

Any updates OP?

I tell my personal update
I think the cookie sheet shroud doesn't work. Companies make it but it doesn't have the correct dimensions that a real fan shroud have. Compare the stock fan shroud to an aftermarket

I spoke to an radiator engineer and in short he said that cake pan will not flow the air in and out

i drilled lots of 1/8 inch holes in my tstat allowing it to flow more coolant.

i noticed that once my oil starts creepin up past 210 the coolant is only a few minutes behind.

control the heat soak thats going on, as well as keep oil temps cool as possible and i think the coolant issue resolves itself

I understand an inefficient T-stat housing by using a single drill opening, but not Speed Holes by drilling multiple holes in the T-stat housing.

lol your not supposed to drill more holes in your tstat, all that does is relieve the pressure behind it and prevents it from opening effectively.

The biggest thing I could have ever done to help my cooling system overall was an OEM tstat from a B20, which was 180 degrees from honda. It is HUGE by comparison to the aftermarket tstats. I used to run 200-205 degree ECT's on my aftermarket 180 tstat (stant and gates) with the same full size radiator and 50/50 coolant. Now I barely get above 180 and on a short cruise on the highway it will go down to 179 and the fans wont even come on. I didnt want to believe that the aftermarket tstats were some how inferior to the OEM's because the aftermarket has come a longgggg way in terms of part quality compared to OEM's since the 90s, but in this case. OEM is the only way to go.

If you want to squeeze a little bit more out of the system, run water wetter, and 70/30 coolant mix.

Lmao
I remember that episode
I was thinking the same thing when I read the original post

I got rid of my a/c condenser in my DC chassis. installed a VW dual core aluminum radiator in place of the condenser in the rad support so I effectivly have a full sized rad now. Its also dual pass design. In 95 degree heat the car stays 185-190 driving and boosting. Only gets hot 200-205 when at a stand still. once start driving temps go back down as they should.

i would also like to add that im only running a single 12" Zirgo fan on this with a sheet cake pan and it pulls the heat from about 7% of the radiator and works wonders. Im hoping with the new manifold i will have a little more room and im goign to buy the OEM vw dual radiator in the oem shroud that will bolt right up and give me much better cooling effeciency from the fans vs a single 12" its a dual one 12 and one 10

Do you think can share some photos when you do this?
Even though I don't think I'll be able to utilize this setup because I'm going to put a oil cooler on my car but I want to see this. I may want to do this once I decide to build a autox teg

You can still run an oil cooler plenty of space. I will post pictures when I put my car back together

Sorry i never posted pics of my radiator install here are a couple i recently took.

Is that the vw radiator?

iTrader: (2)

Yes

So how's fitment? Anyway to do a quasi backdoor setup for the hot pipe?

I'm wondering if I can run this with my evo8/9 based turbos with a block hugging ramhorn ,manifold.

NateCr3

I have similar problems can drive around town all day or short highway trip coolnt temp
stays 190-195F. Longer highway trips about and hr coolant temp just creeps up to about
220F. Have full race prostreet with single back door intercooler made into double backdoor. Dont know if you have ever seen these intercoolers but they sit offset in front bumper. Pass end tank of intercooler basically sits directly in front of rad so it blocks alot of airflow. Have manifold and dp hypercoated and turbo blanket. Dp almost touches fan shroud. Have mishimoto rad with fal fan- has a great shroud on it. Seems to me problem were all having is heat soak issues. Either from oil heat soaking coolant ie stock oil cooler or just high underhood temps or poor airflow at highway speeds?? Lots of good ideas on here. Anybody actually fixed this problem 100%. Turbo-ls setup is diff than mine as mine is a bottom mount as both dp and turbine housing are alot closer to rad. Sorry for such long posts!!

i might have to try this vw radiator. even tho i think it has less total surface area, i run way to hot on road course being a turbo gsr too

I came across this thread a few days ago hoping to cure my issue on the freeway as well... Here is what I did

Making a blockoff plate/shroud like that is common place for turbo apps using a halfcore

I feel better now in knowing that im not the only one having the heating issue... I wish It can be solved.... Ive done everything except drive without my hood lol...
