  1. Thermostat gasket

    Alfa 147, 156 & GT
    Hi all, I'm changing the thermostat on my panda this weekend. Thing is I've got the part but it has no gasket. Pretty sure when I did my 156 the thermostat (circoli) came with a rubber ring. Is this a new type of fit? Is a paper gasket still a thing or do I need magic paste or will I be able to...
  2. QH thermostat and temp sender problems 2.0 ts

    Alfa GTV & 916 Spider
    Thought this thread may be of interest and I hope to get some experienced comments by return. I acquired another TS GTV and set about sorting some running problems. I had a cold running problem which I fixed by changing the maf and repairing a hidden air intake pipe split. But MultiEcuScan...

    Alfa 147, 156 & GT
    Hi Can anyone help work out what I need to change the thermostat? Ebay seems to only want to sell me the whole housing rather than just a thermostat on its own. ta.

    I have an Alfasud 1.5 engine with a sealed thermostat body. I have been unable to find a replacement anywhere online. Are these now discontinued and is there an alternative? Had anyone tried to split the body and reseal it , chemical metal or the like? Any help appreciated.

  7. 147 1.6TS thermostat - replacement & guide?

    Alfa 147, 156 & GT
    Hi all, I noticed yesterday that the thermostat in the other half's 147 appears to be stuck open. When driving normally it doesn't go over 75C, when parked it rises to 90C and stays there, then when driving drops back down. This implies it's stuck open if I'm right? I can see EuroCarParts...
  8. Blown thermostat housing

    Alfa 147, 156 & GT
    Fitted new thermostat housing yesterday and this happened while out in it. Temp didn't move above 90, will I have wrecked the engine and what would have caused this? Sent from my P8_Mini using Tapatalk
  9. Guide - 1750tbi thermostat replacement

    Alfa 159, Brera & 946 Spider
    I’ve tried to go into a little more detail with this guide than I usually do, in the hope people who lack experience are willing to give it a try - it’s a relatively easy job, that can be done with a pretty basic tool kit. The only specialist tool I used was a pair of “clic r” pliers...
  10. Thermostat Housing & Bottom radiator hose

    Alfa GTV & 916 Spider
    Hi fellow enthusiasts, I live down under in Australia and need to replace my thermostat housing on my 1998 phase1 2.0L GTV TS, due to the T piece underneath breaking off. Everywhere Auto shop I’ve tried in Australia is quoting me on a thermostat housing that doesn’t have that T piece connection...
  11. Thermostat issue

    Alfa 147, 156 & GT
    Hello all, I just fitted a new thermostat housing on my 156 jtd and have just noticed that the plastic fitting that takes the hose off to the heater matrix is loose and rotating in the thermostat housing. I can’t pull it out but the fitting in the original is solid and unmovable even with the...
  12. Thermostat woes...

    Alfa GTV & 916 Spider
    I changed the Spider thermostat today for a genuine Alfa part. However I now have two problems; first of all a very slight leak from the thermostat itself. The old one was fine and didn’t appear to have any sealant etc used just the rubber gasket so I did the same. Any suggestions as to how to...
  13. Thermostat housing seals (o-rings)

    Alfa GTA
    I'm having a hard time finding the right part numbers for those seals. There are 3 pipes coming from the engine that connect to the thermostat housing unit. Each of them has a different diameter. Each pipe has 2 seals. For one of them, the pipe coming from the water pump it should be this one...

    Hi Hope someone can shed some light on a suspected thermostat problem with my GT JTD I replaced the thermostat after i bought the car in june (every car i buy seems to need that little job doing) and temp gauge has shown no issues on a journey since, goes up to 90 and stays there.

  17. Thermostat compatability

    Alfa GTV & 916 Spider
    Anyone know if a stat from a 2.0 JTS engine will fit a 2.0 TS engine? I know that the connections are different underneath but could the T section be taken from the old stat and reused on the JTS stat? Mine is running too cool since being away, barely going over 70deg unless at standstill and...
  18. Thermostat replacement

    Alfa GTV & 916 Spider
    Hi all, i’ve been losing coolant for a couple of weeks and I’ve just noticed that the thermostat is leaking, going to have a go at changing it myself, the one on the car looks like it’s got silver sealant on the mounting, but the how-to guide that I’ve read on here mentions nothing about using...
  19. 2.4 Thermostat change coolant quantity?

    Alfa 159, Brera & 946 Spider
    Hi, My 159 2.4 has recently stopped warming up... as in it takes about 15 minutes for the temp guage to move at all while it's ~12 degrees C outside. Safe to say the thermostat's gone and my replacement is already on the way. My timing belt and water pump were changed about 6 months ago with...
