Having had overheating due to low coolant level, I'm considering fitting a coolant level sensor to my TF (2003 model). If anyone has experience of either the MGOC or Rimmer Bros kit, I'd be grateful for any feedback.
Thanks
John

No experience with either, however I did fit the Brown & Gammons variant over 11 years ago (although I didn’t pay £167.94 for it at the time) and it has saved the day twice in that time so regardless of the type I would say it is well worth fitting and should have been fitted by MGR from day one.

Thanks, Chris -- and for the link. My wife had a late 2005 TF a few years ago and that did have the sensor fitted as standard which, like you, i thought was a really good idea (having had HGF on her MGF some years ago due to coolant loss)

I put a TF bottle and sensor in my MGF, hooked up to a delay timer relay board I got off ebay for cheap. This is a less costly option if you have some basic electronics knowledge it's not hard to do.

However the genuine TF sensor was expensive rubbish - intermittent function. I replaced it with a generic reed switch which works fine with the TF float / magnet, costs a fraction of the price, and it has been very reliable since.

It has definitely saved me one overheat.

From my recent experience (see HGF new year post) any alarm you fit will be worth it, may well have saved me a lot of money, but I am lucky, my 2004 had the wiring and dash light already installed. I just had to change the tank. Even at 170 quid from B and G, think of the possible long term savings and piece of mind. There are several posts about a DIY option if money is tight, this is one: Contactless low water coolant level alarm project. use original expansion tank

The low coolant alarm kit available from Rimmer, MGOC Spares, and B&G are all the same kit. Although expensive, it only has to save you once from overheating the engine once to pay for itself and then more.

This is the kit from the guy on the T-Bar: MGF / MG TF - LOW COOLANT ALARM KIT - No Drilling Required | eBay

I believe Mike Satur is/has developed a low coolant alarm kit as well; supposed to be much cheaper than the one from RImmer, etc.

I had a kit made specific for these cars but I can't remember who by, I know it came with the bottle, wiring, control box, warning light and beeper, quality kit, think it was only about £100.

I’m contemplating making one using a non contact sensor fixed to the side of the expansion tank

When 10 years ago I fitted my level alarm I remember the same discussion here in the forum.
I fitted OEM Tank+sensor with a simple 12V beeper masked hidden under the moquette engine cover, at 20 cm far from my head, without any delay ! Due to the lack of delay the beeper is sometime ON (i.e. when in a road round about - note in Italy we turm clockwise, or when the engine is cold) BUT this is like a check confirming the system sensor+floater is OK. B&G kit is true that provide a safety check at start-up but it does not check the real sender/floater operation. In case of HGF it can occur that some majonaise blocks the floater in upper position. Some frends of mine lost the magnet glued into the floater, hopefully it remains on the bottom of the tank

I went down the contactless route using this Balluff liquid level sensor. It lets me know when the level drops exactly halfway. There is no dwell timer fitted, but with the coolant filled to about 5mm over the seam on the tank it will not signal. At exactly halfway level it will begin to flash when I take a hard left hand corner, which is good to know its still working ok, although I check it every year when I service the car. So far its been excellent and does not seem to be affected by the high temperatures that the coolant gets up to.
Here it is shown on a mock up on the bench.
