rx7 fd3s water problems
 

Hello,

I am owner of an RX7 2002 build type RS. The car is in stock condition (as it comes out of the factory) it has 33 km and it had never been rebuilt or change its engine. I have tested the compression ratio which is very high almost like a brand new RX7. However I am facing with some problems


Below are shown the problems the cars shows:
1. If i drive the car in the noon i get high temperatures (i dont have any temperature meter besides the stock one whos bar is raised up to the center of the graph and can go even higher) . I assuming that changing the stock intercooler and radiatoor will help reduce the heat. I am thinking of an fmic, I know that they are many out there but if you have personal experience please share with me, i was thinking of going with Greddy spec LS, which is low cost considering others and eventually will help the car breath.

2.A very strange thing that is happening is that i can't fill up my radiator I place water in it and it drinks it, i checked below of the car for loss and couldn't find (Ps:The extra water tank hasn't got a cap and i thought that the radiator pulls air from that tank and thats why it never fills up).Is that logical explanation ??? (How often do you place water in your car ? I have to do it every time i drive it ! else i get that sound of water coolant need)

3.Every time i drive the car (no matter how i drive it) my water is bubbling in the extra tank! Is this is a warning of bad water seal or is it because iam in a hot country and my intercooler + radiator can't help at all ? Have in mind that i dont have white smoke out of my exhaust (To find out more about this i am thinking of doing a head gasket leak checker is there anything else to do ?).However if this is the case and i have bad water seals is there any way that to prevent my engine from been open up ? I quess not but how long this engine will take me if i have this signs now ?

ps:... and yes the car has been sitted for some time (2002 production unit with 33km) however no startup problems at all...

Sounds like a coolant seal is shot
