306 Temperature drop - Thermostat replacement

As I read in the technical book, which I have learned from the service and found on the internet, there is a thermostat of 89C in 1.4 and 1.6, and 83C in 1.8 and 2.0. As far as he wrote in the booklet, he writes that the thermostat started to open at 83C and that it hurts at 89C. But with the original thermostat, while watching at certain speed both in summer and on the straight road, the temperature decreases up to 70. If I do it on the face as much as I want in summer heat, it does not reach 80 again. stop up and go up to 100 and the fan hurts. no problem here. In the meantime, I found out that the 1.8 and 2.0 engines that peugeot revised were replacing the thermostats and using 89C. besides; A 1.8 engine XU7JP4 83C, the new EW7J4 89C, the old 2.0 engine XU10J4 83C, and the new EW10J4 thermostat 89C. besides the factory has lifted the 83C thermostat ... The fact that the temperature is so low causes a decrease in heating efficiency since the heat could not produce sufficient calorie temperature in the summer. I spoke to many masters, I researched. 1.8's always been tall. I thought the thermostat hurted a little early. I run it when it was cold to check and I waited for the engine to warm up at idle. While the indicator was not even 75, hot water came to the radiator. I couldn't make sense of this event. I said, let me change it because I think the thermostat will open early. The original "colorstat 83C" thermostat came out. Based on the information I explained above, I installed a different 89C thermostat. Because the original has no 89C ... Now my heat does not fall like it used to be. I achieved at least 11-12C more than the old one. Now my heat never goes below 80. it usually travels between 80-85. In this context, as I had a warmer operation, I had the problem of not being able to warm up sufficiently. My new 89C thermostat. A product made in Italian ... Thermostat box ... On the left, the socket slots, on the top, the breather bolt, on the right, the hose to the heater. Thermostat cover. Kutuk is the superior 3 lords. It gives information to the blue indicator, brown fans and green to the ECU. The thermostat box is removed from the cylinder head. As you can see, we are in the canal. At this point, the importance of using antifreeze is very large. Summer should use half-half antifreeze ... cecoli2011-04-13 14:07:19

maşallah thanks to you, we are learning from you too

If you remember the text, I told you that the thermostat was defective as soon as I got into your car :)) beforehand, it was falling under the blade of 60C. It is like staples. It hangs around 90C right?

Yes, when the brother opens the thermostat, it goes down to 85, but other than that, it is pebbly at 90.

In my car, when the thermostat turns on like 90, the temperature drops to 80 and then hangs between 80-85.

Thanks for the photos and information.

Thank you, it has been a good work.

slm you are giving really useful information to everyone
