[Fot] TR8 Water temperature

[MadMarx]

Hi Jeff,

 

Yes, the tank ist he highest point of the system.

To remove the air from block and head I take out the temperature probe at the thermostat housing and let the water climb until it comes out and put then back the probe.

 

Cheers

Chris

Hi Chris,

 

Is your expansion tank the highest point of your cooling system? You stated that the expansion tank has a connection to the top of the radiator to remove air from the system. However, the radiator is not the highest point of the system. I'm not sure what intake manifold you are running, but you should have a line that runs from just behind the thermostat housing (on top of the intake manifold), to the top of the expansion tank. This allows trapped air in the system to bleed out into the expansion tank. If you are running an Edelbrock Performer intake manifold, you will have to drill and tap a hole into the top of the manifold for a hose nipple. 

 

Hope this helps,

 

-Jeff De Pol.

Easiest way to confirm a water gauge is to immerse the sensor in boiling water which is a known temperature as a reference.

I hate to ask Chris, but I've seen this before: are you sure your gauges are accurate? I saw this problem on a well known car a while back.

Electrical or mechanical?

Could be worth checking.

Good luck.

Bill

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
