[Fot] To thermostat or not to thermostat...

[tr4racing at googlemail.com]

I disagree on this, I never ran a shroud. Certainly it does help….but my cooling system is so over the top that I need to run a thermostat to get it to operation temperature or I see 160F.

 

On the photo you see the ready to race configuration.

 

Cheers

Chris

Radiator shroud intact?  That's kind of vital.

Somehow your radiator system is inefficient.

My TR4 temperature is nailed to 185F and don’t move away from…range maybe from 180 to 190.

I use:

1.	Good aluminum radiator
2.	Blocked small circuit
3.	Automatic bleeding system
4.	7 blade pump
5.	Smaller drive pulley to lower water pump speed

Yeah, that was my thought.

 

Besides that, I use a thermostat in my TR4.

 

Cheers

Time to get the radiator flushed.

I have the thermostat housing open right now and have obtained a new 180 degree thermostat to replace the 180 degree Motorad one that has been in there since the 1990s.  The old one I put in a pot and saw it open when I heated the water but It is still suspect.  Here in the Phoenix area it is the rare day that we really need to be concerned with ambient temps leading to prolonged engine warm up conditions. Lately I had noticed that when running for prolonged times at Freeway speeds (+75 at 3500 RPM) the temps would quickly reach +230 and if I jumped off the Freeway and moved at surface Street speeds of 45 even with Stop and Go streetlights within a mile or two the temps had dropped back to between 210 and 220.

 

Should I look at using a 160 degree thermostat or just ditching one altogether?
