can u help I recently bought a te20. Just for my life style block. She will tick over no problems. But after about 35mins of harrowing a 3 Harrow set up. She started to over heat steam and water from the over flow pipe on rad let it cool down then she sweet for another 35 mins of farrowing. So I looked in rad cap there was a few little bubbles when ticking over even revved hard a few bubbles did not get more or over flow out of rad so I looked at thermostat there was not one so took rad of to clean there seems to be a good flow through it but I can still see a few bits of dirt in there through the cap The water pump looks good to u can see it flowing in rad. I had it filled about 1inch from cap? should I put a new rad on and fit a thermostat not to sure how to tackle this would a thermostat help control the heat better or was it removed for a reason. any help would be grate thanks Steve
