thermostat housing ?

Postby raphsolo » Fri 23.09.2016, 13:13

Hello !

First, sorry for my english !!

Well, i changed my temperature sensor for engine management, but i screw it too much and i cleave the thermostat housing or outlet spout...i don't know if it's the good word...this is the metal part where you have hoses and sensors...
I can put a photo latter...

Where can i find this part ? (outlet spout ou thermostat housing)
It's a turbo M100...

thank's a lot

Sorry to say, but the housing (A100E6348S) is no longer available from Lotus brand new. Best to try small dealers who might have old stock or breaker yards. Might be a chore in France, but there are many breakers in the UK.

The housing for a Non-Turbo M100 is DIFFERENT so be sure you are getting the correct one.

Maybe someone on LEC has a spare engine that could offer the part to you.

Phil: He said it cracked while changing the temperature sensor for engine management which is in the housing attached to the head, not the inlet spout. I think the switch in the spout is for the coolant fans?

You are right !
and the switch in the spout is for the coolant fans and electric water pump (when the car is off)...

So i need to find the housing attached to the head :?

From the Wiki
6) Screw in new CTS. ***DO NOT OVERTIGHTEN AS IT HAS A TAPER THREAD AND CAN CRACK THE HOUSING***

As has happend in your case.

For that reason they are difficult to get.

Another observation:

Tapered sensors/senders usually DON'T need Teflon tape. More importantly, Teflon is "slippery"! When you use it on a tapered thread, the "friction fit" feel is severely diminished and it is really easy to over-tighten the fitting which acts like a wedge and splits/cracks what it is going into.

Also, Teflon doesn't conduct electricity very well, so switches and sensors that are making a connection between something (like the fan relay) and Ground/Earth don't do a very good job. Same for single connector senders like the temp gauge sender.

They are tapered so when you get them snug, they are self sealing (if the threads are not severely damaged).
