Hello

I'm having some issues with the cooling system in my 110" TD5 from 2002. And I would like to see if the issue is from the EGR cooler.

My question is if it's possible to simply bypass the EGR cooler, ie. connect the two coolant hoses to see if the problem is the EGR cooler?

I haven't blanked the EGR valve.

Can you drive the car without the EGR cooler in play?

I don't see why not. Earlier TD5s didn't have the cooler at all. It was only added when they changed from the 10p to the 15p engine.

What about the exhaust that goes through the EGR cooler? It won't be cooled before entering the engine again, right?

This will not be a permanent solution just to drive a short trip and see what happens...

The 10p engines just had a pipe from the exhaust manifold to the EGR valve on the inlet manifold, and many of them are still running, so I doubt if it would do any harm if the cooler were disconnected from the water system. As you're probably aware, a lot of people fit an EGR blanking kit anyway.

Get rid of it and blank off the entire system. Mines a 2002 TD5 got rid of that soon as I bought it, no issues what so ever. It was fitted to pass emissions standards they get blocked as well as pushing filthy exhaust gas back into your engine.

I would blank the whole thing exhaust side and cooler side.
Im certain the cooler is there for a reason, most likely to meet later emissions the 15p egr passes more ex gas than the 10p lump and so its needs cooling more, hence the cooler, but for a short test cant be a problem.

I removed both egrs abd coolers on my Defender and Dad's Discovery. Runs fine with no problems.

Tidies up the engine a little bit too

It works just fine bypassing the EGR cooler. Unfortunately it didn't solve my problem, which means new head gasket
