Hi guys,
So finally after 4hyrs the cat has started first time it was running a bit lumpy but that was to be expected what wasnt expected was the sheer heat and smoke coming from the exhaust system from the engine.
It has a new water pump fitted the fan belt I can turn about 90° so it is tight but not loose I took the top hose off and inside feels damp but not wet

I dont want to keep trying incase I brake it or it catches fire but just need to know please guys what's best course of action

Hi guys,                              Cat or car ?
So finally after 4hyrs the cat has started, first time it was running a bit lumpy, but that was to be expected, what wasnt expected was the sheer heat and smoke coming from the exhaust system from the engine.Out of the exhaust    or         outside the exhaust ?
It has a new water pump fitted the fan belt I can turn about 90° so it is tight but not loose I took the top hose off and inside feels damp but not wet                                   

I dont want to keep trying incase I brake it or it catches fire but just need to know please guys what's best course of action

 

Make sure the rad is full of water next time you start it up, and have a handy hose dribbling water over the exhaust if you are worried about too much heat as it settled down.

Rad is full and still is after starting up and running has gone round the system. Tested thermostat and it worked fine water was sitting at the head level underneath thermo bracket. Smoke from the exhaust outlet underneath the injectors blue/white colour

Which water pump did you fit?

 

I had an overheating issue with my son's Mini even after fitting a new water pump. Swapped the pump again for the Minispares version with the glass filled Nylon impeller and it's been perfect since.

So I've read that drilling holes about 3/4 3mm on the t stat flange is a good idea for ones that dont have a bypass hose required? Mines fitted with a 88°c stat and has one little hole made from factory

If I'm understanding correctly, when you fitted the new water pump you changed to a version without the bypass?

I'm gonna give the radiator a flush buy an 82c thermo add a few holes to increase the flow of coolant until the stat opens and see if that runs and better!
