my rex keep over heating so drained rad and engine coolant filled back up and burped it for two day went out in it over heated.
so tryed the coke bottle in the filler neck and there was small bubbles when it was cold and when engine go hotter big bubbles started to come up and the water level started to rise. think my water seals have gone :Hammer
im running a v mount on it but stanard rad so could it be that ? thanks for any help

Sorry to hear you have problems

Has the V mount just been fitted and do you have gurgling noises when you turn off ?

[Nik da Greek]

Did the water rise really quickly and straight away and were the bubbles violent, or was it quite slow and took a long time? The former is bad, the latter not necessarily. Did the bubbles ever clear, or keep coming up no matter how long you ran it?

v mount been fitted for a while now and i started it up and there was big bubbles coming up and when the engine got hot the water started to rise in the bottle still big bubbles were coming out, tonight i put some vaseline around the ast cap went for a run was fine driving but as soon as i stopped at traffic lights the temps when up to 112.

i put a new stat in it last year but ill try anything a moment and cant find any ast caps on ebay where can i get a new 1 from or will a fc one do the job

Clive at Mazda Rotary Parts has caps in stock usually. You want the 0.9 bar one, not 1.3.

You can get alloy ASTs from various places, Newera or RHD Japan will import you an Amemiya or similar one for probably a good hundred quid. Or WGT always used to do their own alloy upgrade for a lot less (and nearer)

ok thanks ill have a look there

[Nik da Greek]

Or try Jit or Martin at Speedline, they may have a stock one from a breaker that\'ll at least let you troubleshoot yours. Admittedly, stock ones are all timebombs...
