Strange problem, Loosing cooling water through radiator cap!

Hi!

 

I have a strange problem, My radiator is loosing coolant, Not very much but a few drops every time i´m using the car! So after filling the reservoir bottle to MAX level after 1 week its almost empty! I have now tried 2 different radiator caps brand new :

1 from TRD 1,3 Bar opening valve, and 1 from Blitz also 1,3Bar.

And its still loosing coolant from the rad cap!!?? And another thing.. I don´t think my radiator is stock because first time I purchase a TRD cap for a Supra -94 (JZA80) and that one didn´t fit! So i have to get the other type of rad cap which is as far as i know the "OLD" type .. Type "S" and that one fits ... but as said it leeks coolant, just as much as the stock rad cap :( :(

 

And i can also say: My temperature is normal when i look my stock temp gauge inside car.

 

I hope anyone have a clue what it can be :(

 

Many thanks :)

The wrong rad cap!! Try and find out what rad you have and then contact the manufacturer or check on the net to find what cap you need.

 

Post a picture of the rad up and lets see if someone can tell you what it is & what cap it needs.

I dont know the fix for your problem.

 

Just be very carefull with rad cap problems as i had a rad cap fail on me and had to rebuild my top end due to a vacuum being created in the system which inturn caused overheating and warping the head!

 

And it didnt even register high on the temp gauge!

Here is some pics of the radiator and the stock cap and the blitz cap! Maybe someone can see if its look like the stock radiator, or what it is? Both caps fit but with the brand new blitz cap i´m loosing more cooling water then with the old "stock" cap! The blitz is not so tight as the stock one!

 

I have also uploaded some more pictures here >>

Thats not a stock radiator, thats why the caps arnt sealing proporly, you will need to find out what make of rad that is, then get the propper cap for it.

 

Looks like a calsonic rad tbh or very early fluidyne
