I just bought a 94 RX-7 MB. 2 days after I got it the stock intercooler cracked so, Like a DumbA$$ I went out and bought a brand spakin new Koyo not doing any research on cheaper prices like here, and installed it. Everything was going fine untill last weekend I left it sitting all weekend got back in it and started it and the add coolant light was on. So I added coolant thinking I didn't fill it up all the way or something. Now every other day the add coolant light comes on and I have to add some coolant. It's been about a week and I have added 1 gallon total. Need some help.

 

the stock radiator cracked?

usually it can take a few days or even week or so before the coolant system is fully burped, I carried a jug of water and coolant around in my car just for reasons like that. Just keep burping the system

 

either your cooling system was bled impropery, your AST is leaking, or you need to tighten the drain plug at the bottom of the Koyo, and check all your hoses. ALL your hoses.

 

yea jus burp the system

 

The drian plug is tightend all the way and there is no AST(that might have something to do with it. I only have 2 hoses coming off the radiator and one going into the overfill tank

 

just keep blurping the system?? you mean just adding coolant and water to the car?

 

Yes,

Start the car, wait until the needle goes to the middle, shut it down, let it cool for few hours, and fill it up.

After you do this 4-5 times and still you have to add half a gallon of coolant, than you might have a leak somewhere else. Get a pressure tester and see if your coolant system looses pressure. good luck!

 

makes sense will try

 

where do I get a pressure tester??

 

Autozone will let you borrow one for free. you would have to make a deposit. I have one that I never return back to them.. I think its too late for me to do so.

 

Koyo makes intercoolers?

 

I'll go there after work and Advanced Auto does the same thing and well I'm in the same boat. I borrowed a couple different tool cases which I had to put a deposite on all them and forgot to return one ohwell they got my $$$

 

lmao i didnt even notice that

 

lmao I have been thinking about and searching for intercoolers for the past 2 weeks anyways I didn't put fluid in my intercooler I meant the radiator

 

I took me almost a week of driving and filling my radiator tell the light/buzer stoped going off, after I installed my Koyo. Still carry a gallon of 50/50 mix in my car incase.

 

 

well it took it about a month before this started happening? I just don't understand and yes I carry a 50/50 mix with me everywhere as a just incaser

 

Everytime you drive and the car is cooled down, just fill it up. Correct way is to open the ast and fill the ast first, than the filler neck.
