New Style Ottersat Replacement Part Available To Order
#1
been having problems with fans not cutting in when engine runs over normal,when two wires are joined together from otterstat fans will run meaning otterstat failure, new otterstat fitted after tested in boiling water, , fitted to car run to temp ,fans will not run ,replaced with another otterstat, run to over temp ,still no fans,after several attempts of trying different possibilities still no result, so Dickie H was contacted and came over about 5 30 last night to help me resolve the problem after hours of testing electrical and water flow he finally figured out the problem,the spring clip which holds the otterstat in place was putting to much pressure on it ,stopping it making a circuit. So just wanted to say a very big THANK YOU RICHARD for sorting out the problem for me hope you got home safe after leaving at 12 45 am hope you were,nt late for work this morning

Glad you got it sorted these really are a load of crap, I have gone through 4 in 3 years now. There must be a better solution out there for these!

Odd. Mine was bad when I first bought my car and I replaced it then (6+ years ago). Been fine ever since. Same goes for my angle drive, I have yet to lubricate it.

We have had similar woes recently - ancient otterstat replaced with a brand new one, up to temp, fans didn't cut in. Shorted wiring, all fine. Another new stat bought, tested and fitted, haven't been up to temp yet but I've fitted a bypass switch just in case. The metal spring clip did seem to be exerting rather a lot of pressure on the bottom of the otterstat, but then I'd assumed that was necessary to keep a good seal on the rubber. The first 'new' one as removed seemed knackered. Is it too much pressure from the spring clip, or poor quality new components?

A bit of both I think...

After having 3 otterstat fail in quick succession and with the Lotus event immanent, I was forced to take some radical action!

I am pleased to report that my new set up is working fine. Fully adjustable temp and no leaks. I attach some photo's.

The layout in the engine bay RHD cars is slight different . Don't let that confuse you, the otterstat is in the usual place. The kit cost about £30 on ebay http://www.ebay.co.uk/itm/400742005146? ... EBIDX%3AIT and only took 24 hours to fit, because I chose to glue the little 'rubber wedge piece' in position….which allows the capillary to pass into the bottom hose. You can just see it in the last photo.

The first picture gives you an overview of the complete setup.

I will be posting some pictures of a new screw in type otter-stat kindly made by a skilled club member!

Right then, here is the upgraded pipe with screwed otterstat housing. The are also pictures of my previous failures!

As you can see the switching temperature range is ( deliberately) slightly lower at 88 / 79 degrees.

If anyone wants one they are £35 each, but if we can get 10 firm orders the price will drop to £25.00 ( plus a bit of postage)

The fact remains that the easiest ways to wreck one of these engines is to let it over-heat a couple of times. I personally will be staying with my adjustable one, because its now fitted and working, but if you want to keep the (almost) stock look, this could be the way to go.

Contacts through me initially please.

Does the thermostat protrude further into the pipe than OE or similar? How freely available are the new style thermostats?

The thermostats are readily available . They don't protrude at all…approx 4-5 mm sat back.

They are quite a bit wider that the originals, so good contact area with water.

If Richard H or someone would like to 'road test' one that will be fine. I'm fitting the other one in Pilot 20.

i'll post you one of these out on Monday Chris. You can test it.

Speaking of testing, i'm still very happy with my plastic header tank from Ed. ( supplied via Euro-tec as I needed it next day for Lotus )

It's important to note that this is version 4 of the header tank………Versions 1, 2 and 3 all failed in various ways. This one seems fine up to now, as do the other 3 which are on test.

They are also cheaper than the stainless replacement at about £65. My main reason for wanting one was the 'stock look'…which is great. If I have any problems with it, i'll let you all know.
