My 92's is black and iron. The 89 we pulled is aluminum. A new one i purchased from amazon, spec'ed for a 92 that will be delivered appears to be aluminum. So whats up with that?

The 92 has 85k and all original supposedly.

 

The iron one is four seasons aftermarket.

 

^^^ Yup. ^^^ The iron ones are aftermarket garbage. Aside from looking bad, they tend to rust and you can end up with a galvanic reaction. Swap it out with a stock aluminum piece, use anti-seize on the bolts, encounter less problems.

 

Nasty, thanks. Someone before me got cheap and didnt want to spend the extra $15 for OEM i suppose. You can see from the pic how its all corroded and looks like ****.

 

I'm fighting an "overheating" issue.
Its not exactly overheating. If I cruise the streets low throttle, on the highway, or just idle on the driveway, I sit at 160 with no problem (I just took that nasty housing off and found a 160, that was slightly stuck open, that someone put in).
But, if I go around a corner just 1 time and floor it for 1 second, or just do a 1 second peel at a stop sign, that temp rises up to 210-220 pretty quick.
I haven't hooked a scanner up to it to make sure that's the actual temp.

But I thought while I'm putting an OEM housing on, ill go ahead and put a 180 like I have in past vehicles, as well as do a pressure test and check for air bubbles. The radiator cap is fine. The coolant looks brand new.
I thought maybe it was running lean. Ill check with the scanner this weekend, but I took out a spark plug and found a splitfire (remember those lol) gapped at .045. That seems to be a bit high. And according to wikipedia, splitfire was charged with deceptive marketing and settled 20 years ago. Then sales went down the drain. These plugs must be pretty old even though the car only has 85k on it.

 

Did you ever receive this and was it aluminum?

This one?

 

I dont remember where I bought it, but it definitely wasn't a dorman. It was a Delco if it's still made. If not, I probably picked one up off of ebay. Dorman is last on my list of aftermarket part's companies to trust.

 

My still factory original, is black painted aluminum just like the intake manifold.
