My engine runs really hot. I just painted my heat shield and the paint is burning up. I used the 500* paint. The engine should not even reach really above 300*. Does anyone have this problem of the engine running so hot. I am thinking about going to get a performance radiator, and then an intercooler when i get my supercharger. Also an oil cooler. Does anyone have these products, if so please discuss the pros & cons for me. Specifically the performance radiator and where and how do I hook up an intercooler into my front vador.

i know when i had the 5s, it would heat up so bad the hood would feel like it was on fire. but the temp gauge never said anything was wrong.

Don't make the same mistake I did though...my temp AND oil gauge didn't say anything was wrong....soon after I had a bad rod bearing due to lack of oil and excessive heat...and a bad engine! Just be cautious and keep your eyes pealed for anything unusual while you're driving.

you can find oil coolers in several cars in junkyards
you can find intercoolers (smaller ones) in several junkyard cars |

the 5sfe runs on the hot side.
just keep checking your coolant and oil levels and youll be fine. on hot days i can see tons of hot air coming out of my hood vent. -------------------- 15PSI - 30MPG - Megasquirt Tuned

GREAT!!! I knew i wasnt the only one, so i know i dont have major problems. the question is now, i gotta find a way to cool it all down. so what do u think of the new radiator, and intercooler, and performance oil cooler? will it work?
I just painted my heat shield with the heat paint for engines, 500 degrees. and it burnt up. the engine should not be more then 250-300 degrees, so it is really running hot. has anybody painted their enginge parts and run into this problem... |

Are you talking about your exhaust heat shield? Your exhaust manifold will get very hot. Ever seen pics of race cars and turbo cars with glowing manifolds? 500 degree paint is just not sufficient for the heat shield, but will work on valve covers and the like. |

That's true. The heat shield will always run way hotter than the rest of the engine. I've seen a few people with painted heat shields but i havent asked what type of paint they used.

um.... just a little FYI chrome is one of the stupidest things you can do to engine parts... chrome retains heat reallly really bad... if your already having a problem with heat u will diffenetly NOT want to do chrome
edit: and you might wanna get that thermastat back in there.. its kinda important

are you putting it in the right way?? alot of people will try and put them in upside down without relizing it edit: as for the chrome... if your planin on building a trailer whore then do the chrome... but if you plan on actually drivin it.. then leave the chrome off and just paint or powdercoat it This post has been edited by NEVERSTOP: Mar 26, 2004 - 12:43 PM -------------------- 99 project version 3.0.. hello SEMA 2010 =) |

Your engine overall may be 300 degrees, if you are talking about the exhaust heat shield, you will need at least the 1200 degree hi-heat header paint. and totally clean it 1st, preferably sandblast or beadblast, then degrease it with brakleen, the non-flammable kind, 3rd- use a propane torch to boil the rest of the oil film out of the metal. keep the torch moving slowly, heat it just enough so you see the oil film evaporate, then paint it while still warm, but not hot. I have found this method to work very well, the paint tends to stay on and still looks good years later. |

Powdercoat is NOT a solution for hi-temp applications. It will begin to soften at about 375deg. We powdercoat our race wheels and the heat transferred from the brakes will get the wheels hot enough to soften the powdercoat. They get so soft the brake dust will become imbedded in them. They have to get completely stripped, inspected, and recoated after ever race.
