how do you guys dealing with heat soak..
 

It's summer time again..
When i drive my car, temp is rock solid 180-190 F. (90+F heat outside)

Problem begins when i park the car after driving it.

i can't open my hood everytime after driving my car... I do have a fan mod and koyo.

I even left the fan on for 3-4 min after parking but that doesnt help alot.. My temp gauge still reads above 210...


how ya deal with this?

As long as you have adaquate glycol in it, it will not boil at 210. In fact it will be good up to 240 or so with 50/50 (what I use). It's normal for any engine, not just the rotary, to heat up after stopping. Check out under the fronts of cars on highway rest stops. About 1 in 20 actually boil out a little coolant.

cool thanks!

vented hood does wonders..

Drive as least as possible
Get an everyday driver for the meanwhile.
Just drive at night

Upgrade the radiator (if you haven't already), make sure it's a good fan you have, and above all else make sure that the radiator is filled properly with the proper ratio of coolant.

As mentioned above a vented hood will help a lot as well. You can duct hte rad too to help.

consider yourself lucky

today was like 60 degrees and it was pretty windy so it was nice and chill, i had a sweater on..

anyway, i was driving and my temp gauge would reach a peak of 198f, then back to 190 and just fool around between there..then when i shut it off, it would jump to like 204 and stay there for a while.. mind you i have the fan mod and I ALWAYS let the fans run for about 10-15 min with the hood open whenever i stop and park..

this is 60 degree weather, im afraid for the summer..

o btw, i have the stock radiator

Upgrade the radiator (if you haven't already), make sure it's a good fan you have, and above all else make sure that the radiator is filled properly with the proper ratio of coolant.

before entering my garage i pop my hood and cruise around 5 mph for a quarter mile and it cools it enough so i can open it up with my hands.

I did all those things until I got my vented hood. It's amazing how much heat escapes. The difference is night and day.

Ceramic coating items related to turbos, intake and exhaust does help a little.

Where did you guys get the vents at?

evot23 what kind of vented hood do you have

try this (i have always wanted to but i never had enuf money)....

first buy a turbo timmer and rig it to keep only a switch/relay on. then buy a inline eletric water pump and place it someplace between the engine and radiator and have the switch/relay control it, then when you turn your car off, the water pump will keep the fluid circulating and should keep your car fairly cool. oh yeah, buy a scoot hood too, cant hurt :D

You mean this?

My electric water pump comes on based on a temp sensor mounted to the filler neck. It activates both the pump and fans to cool the car down. I haven't seen it go above 210 after shutdown with 80 ambient yet. I'm waiting for the real test this summer.

I'm getting the VIS knight sports replica CF hood. Is this the hood you have evot23? It doesn't have as many vents as the scoot but I'm itching to find out how beneficial it is. Sorry for the thread jack, back to the issue.

I have a daily driver that I drive, with A/C, that I've been driving in the heat. I can't stand not driving the 7 during the day.

Bigger oil coolers will help along with the other mentioned items. I'm betting on a vented hood but if I were you I'd pop your hood as much as possible and try not to get caught in stop-n-go traffic.

guess ya didn't read my first post :)
I do have Koyo rad.. I always do turn on my fan when Im near to my destnation. also do open my hood and cruz when im near to my Destination...

summer suxs.
lol

I have a question regarding the install of the electric water pump on the line at the back of the engine. Since this line feeds the heater core, will it flow coolant if the heater is not on? How does the stock system control heat in the car? Does it cut off coolant flow by closing a valve or does it just cut off air flow via a damper?

If it cuts off coolant flow, then I would assume you would have to leave the heater control on full heat.

Does everyone still drive when it rains with a vented hood??What if you get stuck in the rain?Would all the water get into the intake?

Yes I drive in the rain. No the water does not get into the intake.

So let me get this straight...you hit 210 degrees while the car's idling? Or when the car is shut off?

go up to 210 sometime on a hot day..

I usually turn on my fan when temp reaches 200.

My main concern was after driving. I guess i wouldn't have to worry.. Im plannin on changing my thromstat and coolant this week..

joy joy joy :)

a vented hood in the rain with an intake like the Apex-i ot HKS one would be bad. wouldn't water just get right onto the foam filter

apex'i doesn't have a foam filter... at least the power intake like what i have doesn't. the FEED vented hood is nice. the vents are near the rear (windshield side of the hood) and it looks pretty stock otherwise. bit pricey, but definitely a NICE looking piece

on a warm spring day (70f), maybe after like one hard push, then coast, then normal city driving, it will hit like 210-212 but never past 212f, but i always have my fans on during city driving so it drops to 200 right away..
