I decided to start a new thread on this because my previous one has run its course. Because a replacement thermostat is unnavailable for the 16V four cyl 2.0L non turbo, I have been trying to insert a Renault 5 thermostat into the top hose as advised by other members. It does work well but there is a problem: no matter how I try, I cannot insert the stat any further than the widened portion of the hose. This works, but it does mean that the hose cannot sit as well as it should onto the engine and I am afraid that the hose clamp is not getting enough purchase and may come off.
Has anyone managed to push the stat further down the hose?
