So my Nissan 300ZX has gone through two heater cores now and it is due to the fact that there is rust in the coolant and even after changing the coolant about a week later it is a brownish color again. My thoughts are that the past owner used water so the block might be rusted and or the radiator. You guys would flip after seeing the color of the coolant when I first changed it. Any thoughts on what to do other than swap another motor into the car. Any products I can use for a case as severe as this?

Hi.
You could have a gasket leak that is allowing oil into the coolant passages.

That seems like alot of rust...you would think by now something would have rusted through. Can you feel rust flakes in coolant ?
Prestone Superflush I think its called.
After a good cleaning with a flush product maybe something like this would help.

ChattZX,
What year is your 300ZX?
How many miles are on it?
What climate is it driven in?

My 300ZX is a 1990 with 130,000 on the clock and it is driven all year long in temperatures close to 100 degrees to as low as about 10-15 degrees. The thing runs like a top, just this coolant junk is getting annoying. What do you guys think about using this http://www.orisonmarketing.com/corrosion/ercsc/ercsc.html

evaporust is a great product and I would try it definitely. It works by using chelating agents so it should be safe.

Pictures?
Water pump impellers made of iron on these models? If so the thing is probably disintegrating into the system, which will make it hard to clean and could involve a new rad, heater core and hoses + a good flushing to get most of it out.
Always a coolant filter option

The base you need for the spin on filter is LWHB4861 - I think you have to order from them directly, the base is approx 100$ with 3/8 inch threaded ports
Here is one of the later emails from him.
We offer a universal mounting base just like a oil filter base for the spin on style filters. Heavy Duty trucks and busses use this type of filter for their cooling systems. I have attached a picture of our mounting base. I have also attached a spec sheet and drawing of 1 of the coolant filters we supply. Let me know if you have any further questions.

I would love to get one of those nice spin on coolant filters but the price is probably out of my range.
