C4 Corvette Running Hot? Simple DIY Mod to fix!! $25 Bucks 

How did you do that? Mine runs 205-230 on a hot day

Good point! Might get a higher temp one

Great point!

When I bought my 1994 Vette I had cooling issues (although I didn't realize at the time how hot the C4's are designed to run). Close inspection revealed exactly what you said: a bunch of leaves and debris stuck between the condenser and the radiator (maybe an inch of space between them), right in front of the auxiliary fan. C4's suck up leaves like a Hoover vacuum. It's best to remove [a ton of stuff!] to clean it out properly; I was able to fashion a toothbrush on a long narrow wooden stick and VERY GENTLY cleaned the fins (barely touching, as I know they are extremely delicate). That solved my cooling issue. Oh, and don't try using compressed air -- that will bend the fins up faster than you could do it manually.

Is it normal for the lt1 to have low oil pressure ? My 96 vette is normally around he 20s

I gotta 95 vette.oil pressure when warm at idle is around 20 or a bit less.i thought it was low too but after some research gm manual said 7 to 8 psi per rpm.been driving this car 2 and a half years.bought it with 112000 miles has 133000 now. still running strong.

Lmao, you did not go 1.38 60ft.

So did I. Easy 13.5 sec car. Today mine is a 10 sec racer. Sooo much fun because most think C4 are slow.

UPDATE: Called and talked to him about it. I'm an idiot his is a 1990 LT5 engine ZR-1 model. And been a subscriber for awhile John, Always Good content. 💪🏼

My 86 has a fan in the front which I thought was burned out and the Rad fan I use a 210F.deg. switch isolated. She'll hold 220 at stops but needs air when romping around town. Mine still has its original front fan but not used (now I know) Also she's female but still gets up goes when needed. She'a a Looker not a runner these days and a very fun car to have. Even my manual states something about these motors like to run hot but I rather not.

Worth doing? Yes! But a tenth? Not in my experience. Makes hardly any difference at all in ET but it always made me feel better to do it..

Cutting a ram air hole where the front license plate goes was the coolest cold air intake mod back then!

I did that too

Nice! That’s big improvements!

Yes, it works great and did help a lot. I also put an all aluminum radiator in it after this and now it really stays cool. Usually 175-185 degrees on the really hot days now.

? I don’t understand!

Thanks

It’s super fun to drive!

The best!

Yes, and both fans are controlled by ECM. However, you can install a low temp kit which comes with a sensor you can install to the driver side and then splice it to the original wiring. This will override the ECM settings. And the sensor on passenger side is for the gauge.

😂

Yep

Glad you like them!

Yes but it's also normal l98 pressure

I had 1 with 10lbs at idle never went over 30psi under acceleration, still running today

Nice!

The auxiliary one is puzzy ass . probably only draws 5-9amps

@@mariocooldude9092 mine is handling it just fine

Yes, I changed it to 20w50 and it’s a little better hot.

Just done this today and worked perfectly. Thanks for the video.

What are all the mods?

Yeah what are your mods? And where did u get them from?

You're basically always running your engine cold. Don't do that unless you want premature wear. At most put a 200 degree switch, 180 is way too much.

@@ILoveTinfoilHats Well...Now that the weather has heated up it runs at 200 to 210

Oh shut up

@pilotgeorge2000 The engines were designed to run hot. There is nothing to fix. It's a retarded video.

Input 20w50 in it, it helped a little

NEXT, NOW WHAT TEMP T-STAT DO U USE/RECCMEND WITH THIS SWITCH??

@EHUE-kf4ey Run the stock thermostat with that switch.

Probably what will happen is since the sensor for the fan is lower than the thermostat the fans will run all the time and burn the fans up🤯

​@@attitudeadjusted9027hahaha 😂no it won't

😂

New balance kicks, Raybans and a mullet.

I believe it was the grounding wire....I was wondering are both fans running at the same time?

i did the same thing to my 87. no more overheating
