Installed a new sensor and after 20 minutes the gauge does the same thing - goes to 3/4. Strangely enough, the gauge dips slightly when i press on the brakes and if I turn off the engine and restart it goes back down to below 1/2. I am now...

Always satisfying when you fix something and it stays fixed.

Closing the loop. For those curious it turned out to be rear main. I purchased a 2.8 seal and installed it and no more leaks.

Based on this chart and my measurements am using the right sensor but it may be reading incorrectly. Will get a replacement and try again.

Thanks for all the input. I measured the resistance of the sensor and used IR at to measure C at thermo housing. Seems it tops out at 3/4 of gauge and 50 ohms, around 70 degrees. Outcome is that the resistance of sensor is quite low, and gauge...

We fitted a new rad to a 200tdi a few years back, made a big difference.

Always stat first, tdi can run rad so fecked they are only fit for scrap and not over heat. Are the small coolant air bleed pipes still present? Is the coolant system pressurising by to much when at operating temperature?

Give the engine and radiator a good flush, the cabin heater too if you can. No reason to replace the radiator unless it's damaged beyond repair, most blockages can be fixed

I would jury rig some temporary temperature gauge set up for testing purposes, until you are sure the engine is good and you are not going to wreck it. A cheap mulitmeter that accepts K series sensors will do, or cappiliary sensors are the best

That's a good idea. If overheating what could be the main culprits? My radiator is still the brass one. Which i did rinse and back flush but maybe it's time for a new one. I noticed my green coolant turned slightly reddish.

It's measured from top of thermostat housing. Yes i agree, seems ok. Not sure why the temperature creeps up on the gauge though as the sensor was replaced recently.

I think the coolant level is the same but will keep an eye on it. The radiator seemed like its getting hot, and so were both hoses. The cabin heater is bypassed for now.

Hey folks, I’m hoping someone can point me in the right direction with an issue I’m having. I’ve got an RRC with a swapped 300 TDI engine (originally a VM 2.5). The engine’s recently rebuilt and runs great—no smoke aside from a little black puff...
