Thermostat For Hot Weather.

[zekow1]

Hi Guys
Back in 1976 I had a TR7 in College it was in Daytona Beach, Florida.
The car was heating up somewhat.I took it to the Brithish Leyland, Dealership.
The Mecanic ,His Name avoids me, took the thermostat out.
and left it out , He said:
"on your way kid you will not have anymore problem ", And I din't .
If I do this on my TR7 1980 will i get the same results?
Or has the car change substantially since then?

Goes to show you, never trust a mechanic. (had a friend got his brakes bled and they switched calipers around insisting the bleed nipples must be on the bottom.)

While removing the thermostat works on some cars but on the Triumph if you do that some water goes through the radiator and some through the bypass that is normally blocked off with the extension on an open thermostat. You only get get cooling of part of the total amount of water that the water pump is pushing.

If you order a thermostat you're as likely to get the wrong thermostat (I got the wrong one from VB and from Robsport before Robsport sent the right one second time.) With the right thermostat (with extension) it blocks off bypass forcing full flow though rad. If you have the right thermostat and it opens when water is hot (test it out of the car) and you still have overheating problems then the problem lies else where. Dirty rad, partially blocked rad, air bubble, low water level, incorrectly reading sensor or gauge, etc.

Hi

Unless your thermostat is staying shut and you need a "get me home fix" it's not recomended by the experts.

The stat provides some restriction to the coolant through the engine and ensures that all the galleries have the correct flow rates needed for relatively even cooling. Taking the stat out enables the coolant to take the easiest route through the engine, resulting in hot and cold spots.

In colder weather the engine may not reach its operating temperature but that doesn't appear to be your problem if you're asking this.

Cheers,

As stated by Adam and FI nNever take out the thermostat, if the engine overheats check all the usual problem causes systematically.
