this is from fwd beta coupe not sure how it differs for monte carlo , MC has a more Fiat style layout. If you are running front rad mid engine I suspect it will need to volumex/montecarlo type waterpump with deep impeller worth checking as 99% of after market are slim impellers even though listed for monte  

hi rosso many thanks for the info, i will have a good look in the engine bay whe it stops raining. p

p.s. i live near skegness.!

Let me know if you need any other info I have lots of official tech books I can refer to, layout does vary slightly according to engine age also are you sure that it hasn't had  a stat in head modification? In which case stat will be at the head end of the top metal pipe

hi r i am pretty sure that there is no in head stat mod. i am mystified that where you would normally connect the bypas hose to the top water rail already has a heater hose attached. p

Not sure what you mean perhaps you could post a photo?
Thinking about this further I don't think the parts microfiche give the best illustration I will try to find something clearer

Despite it's sometimes dubious value, I think the Haynes has a reasonable drawing of the cooling system layout?

Probably so

no sucess posting photos. have discovered today that there is no inlet for heater hose return on the bottom water rail[just one outlet for heater hose feed]!!!

These are both front drive beta configuration, late cars such as volumex have two extra connections on the top pipe but off the top of my head I can't recall what connects to them but they were designed to reduce risk of head gasket failure.

As I said previously fiat applications are different to the above

Can anyone tell me what the temperature rating of the VX thermostat should be?

Cheers.

Thanks.

Fitted one of these & it works fine.

Just to add to this thread....I've recently had problems with a sticky thermostat, causing the temp to go close to the red.  Having no success sourcing a thermostat locally or off the internet, the ones that were supplied were generic Fiat/Lancia with the by-pass outlet being 35mm rather than 25mm.  Think we're subject to the "one size fits all" from motor factors trying to supply old Fiat/Lancia models.

I decided to fit a 75deg "in head stat" and adjust the pipework accordingly.  The only problem I have noticed after fitting is, the temp sensors for the L-Jetronic are now on the cold side of the thermostat during the heat up period, meaning the fuel trimming for warm up is out of whack...but is barely noticeable and after three miles is back to normal operation.

Which stat did you use?
With regard to the proper beta ones they are available but as with all after market stuff sellers get confused and make false assumptions

Sorry for the late reply...The kit that was supplied to me was in a Firstline box with the part No FTK 002 with "Ford" printed below, also the the part No QTH 101K penned on the white part number sticker, I assume that's a Quintin Hazel part number.

The car temperature has behaved it's self since install, only rising to 3/4 scale in heavy town traffic which was dealt with the fan kicking in and bringing the temp down again...result, fingers crossed!

I spent hours in Friday trying to get a thermostat for a Fiat 131 twin cam to fit in the Trevi (Beta). It just wouldn't because the (larger) top outlet pipe was at the wrong angle and there wasn't enough room to sort out the pipework. I also tried a Lada thermostat but the 'top' outlet of that one came out the side towards the alternator! I didn't even try to get the pipework sorted for that one. So I went down my local motorfactors and they had the right thermostat in stock! Last one of course but just took me 15 minutes to fit!

My 131 (that gengis know very well  ;)) has a thermostat in the head and I've replaced it with a 74 degree thermostat for "Classic Mini" for just a few quid from eBay. I believe early Ford Fiesta have the same thermostat. But when fitting an in-head thermostat you must drill a 3mm hole in it if there isn't one already (most have this hole). There must be a small amount of water flowing through the thermostat to avoid air locks and to help in better "sensing" of the temperature. A small hole may also solve the sensor problem?  

I think your quite right about the 3mm hole Theo.  I did think about it at the time, but talked myself out of it for some strange reason!  I'll catch it at the winter lay off.

3-4 mm hole in the stat will solve the problem. I also made this modification on my 2000i.e.

I have now covered 700miles since drilling the by-pass hole, and the temp rises to a steady 1/4 scale rising to half way in heavy stop/start traffic...result!
