[Fot] TR8 Water temperature

[Jack Brooks]

Chris,

 

It sounds like an air bubble.  Have you tried running the engine with the front end elevated either on a steep hill, a set of ramps or a curb?  I know I had a similar issue on my TR8 and burping it this way took care of the issue.  I know the system looks like it should naturally cleanse all of the air from the system during normal operation, but it did not in my car.  I found this right after changing coolant, so I am not certain this is your long term issue, but it is worth a shot.

 

While I don’t have it handy, I think the TR8 ROM talks about this.

 

Jack

Hi guys,

 

My TR8 is running way too hot about 212F at full speed and at idle the temps are getting that high also. I have no idea to get them down.
Radiator core is 68x48cm x 5 cm. I suppose that should be enough. I've experiment with different restrictor plates with no change. Changing pump speed didn't help either. The difference between radiator in and outlet is 10°C (50F). Not enough I would say. Maybe making the pump more slower? It was running on a ratio of 0.8 slower than crank, currently 1:1 speed. Any ideas? 10 Liters are circulating.

 

Cheers

Chris
