Standard Reliant is fitted with an 88 degree thermostat and some folk fit a 92 degree one in winter .
Never run a Reliant engine without antifreeze / summer coolant at a 25% coolant / 75% water mix in the summer and a 45% coolant / 55% water mix in the summer . 
The Radiator should only be filled to just over the internal fins or any expansion will go out the overflow stub if not fitted with an expansion bottle .
Is there a water hose connected to the rear of the head ?
.

[gazzagood]

Hi fifer yes water running at back of head and got anti freeze in there but can only do 15 miles before stopping to let cool down

Why do you need to let it cool down Gazz? What's the symptoms? Is it throwing water out of the radiator filler neck? Being an aluminium engine, the casings do get hot to the touch -as Professor Fifer says, they're a hot running engine anyway.

Hi Andy yes have to stop let it cool down as last time I rode it. It bloow the bolt out the hose that was capped off from the water pump to the heater and out over flow on rad and rad cap. Bloody water every were good job I had me boots on or would of scolded my leg

Can anyone help on this

Hi gaz. can you post a photo of the rad and pipe set up, and what pipes go were. cant remember Flap having any issues with this when he rode it. mind you it was parked up for a long time.
try running it with central heating acid cleaner like fernox to see if it shifts any crap

[ROD]

my first thought was ^^^^ ! Also if the pressure has blown a bung from a pipe,why didnt the rad cap let go first? Dodgy cap?
 
 Long reach cap on short neck rad?

Does the water hose from the rear of the engine attach onto one of the two hose connections the water pump ?
Do you have a short 90 degree angle water hose from the other hose connection on the water pump to the side of the thermostat housing ?
