How does the 280ZX engine cooling system work?
First, and most importantly, the aperature on the OEM thermostat is around 30% larger! Assuming that they both open the same distance (I actually think the OEM opens further since it is taller) means that the flow through the OEM thermostat is much greater.
What kind of thermostat does a 79 280ZX have?
There are three different thermostats which you can buy for the ’79 280ZX. It seems to me that this is a testament as to how poorly the car can regulate its temperature. I have tried both the tropical 76 degree celsius one and the normal 82 degree celcius one, and, obviously, my car ran cooler with the tropical thermostat.
When did the Datsun 240Z and 280ZX come out?
Here you will find scans of the original wiring diagrams for the Datsun 240Z, 260Z, 280Z and 280ZX from 1970 to 1982. What more needs to be said about the S30 and S130 Z cars?
Is the 280ZX engine regulator a replaceable item?
Therefore, it is not a replaceable item (one of the few poorly designed features of the ’79 280 ZX). The regulator consists of piece of ~45 ohm wire wrapped around a bi-metalic strip with a contact at the end. When the contact is closed, current flows through the wire heating up the bi-metalic strip and lifting the contact point.
What should the engine temperature be on a 280ZX?
I have found that with a Stant thermostat in my 280ZX the engine temperature varies considerably (greater than 10 degrees Fahrenheit variation) while the OEM thermostat regulates the temperature very well (greater than 5 degrees Fahrenheit variation).
Where is the engine regulator on a 280ZX?
It is contained insidethe gauge housing (not on back like most cars) and it is hard wired to the case behind the speedometer. Therefore, it is not a replaceable item (one of the few poorly designed features of the ’79 280 ZX). The regulator consists of piece of ~45 ohm wire wrapped around a bi-metalic strip with a contact at the end.
