Engine heat

[Myristica]

Hey all,

I was wondering if this a commen problem: the temperature below the hood is pretty high.

it's not a cooling issue, the water temperature is good and stable.

But when I open op the hood, and even the outside of the hood itself gets quite warm.
My set up is not so different from stock, the only major changes are a fmic and a fp exhaust manifold. The manifold and downpipe aren't wrapped, but neither is the stock manifold..

The car is a 89 Plymouth Laser turbo model.

Its not an over heating problem? Your just concerned about under hood temps?Correct?

 

[horizontalkev]

That's about normal. When it snows and I leave the snow on my hood, the heat usually melts it away within 15 minutes. I would definitely wrap ATLEAST that downpipe though

 

[Myristica]

Correct it's not an overheating problem.

This is my second 1G, but I don't remember my previous one getting as hot. That's why I was a bit concerned..

I noticed a huge difference when I heat painted the manifold,turbine housing,o2 and part of the downpipe..I used to be able to light a smoke off the manifold.After the heat stuff I could not.

Although its really worn off of the manifold now..But it worked great for a while.

I had the same problem on my 1g eclipse. Water temps were always good but everything under the hood just got so hot it was unbelievable nothing was melting. Except it took out my MSD ignition. I got a talon and it's completely the opposite under the hood temperature wise. Never could figure it out. The eclipse ended up blowing the head gasket when I started it up one morning. I don't know if the under hood temps made that happen or what. The engine had about 155,000 miles on it and I usually drove conservative.

The exhaust manifold is heat painted, the other things are not. I'm planning on wrapping the manifold and downpipe. But I feel like this is just treating the symptoms not the cause.
I recently rebuild the head. I don't really remember if the problem was there before the rebuild as well.. I only had the car for a couple of weeks before the rebuild..

That is so weird your eclipse had the same thing and the talon didn't.. my car has 123.000 miles atm, did the head rebuild about 2000 miles ago.

Your setup is different from stock. One of the biggest changes is the elimination of a heat shield. Stock DSMs came with heat shields on the turbine housing, manifold, and O2 housing.

I combated this by having the O2 housing and FP manifold ceramic coated by SwainTech. This is not the spray painted crap either. I've also adapted a T3 turbine blanket to the DSM housing. Finally, I have the downpipe wrapped.

To original poster I bought a heat blanket from a vender and still run it on my small 16g with a FP manifold to this day you can have your wife sit on the manifold after driving with no pants on and won't hear a peep about heat one of the best upgrades I've ever done and you won't have to waste your time taping

 

[jukebois]

if outside of your hood is getting extremely hot make sure your under hood silver heat blanket is still intact.

 

[Stoneman]

You could install a hood with heat extracter vents. Or use header wrap.

I wouldn't wrap the manifold, i would get one of these.
