Hi guys, I picked up a Mk2 breadvan the other day. From what i gather from the guy I bought it off it'd been off the road for a little bit. I looked underneath today and there was a little puddle and from what I can see and have researched it is the O-ring on the thermostat housing that is coming from the engine. I've found two different size O-rings on parts websites but neither say which size fits the one I want. One has an inner diameter of 43mm and a thickness of 3mm, the other is an inner diameter of 50mm and a thickness of 4mm. I'd rather not take her apart to find out because the leak isn't that bad right now so if anybody knows what size I'm looking for that would be great. I've attached an image of the system, the blue circle is where its leaking from. And if anyone knows how difficult it is to do this that would be great too. Or even if anybody reckons I'm completely off with what's wrong that would be great too. Thanks, Dan
I have a 2001 Polo GTI 6n2 with an issue with the cooling system, namely the car takes ages to get up to temperature, both the top and lower hoses from the radiator are at the same temperature, so I assume that the coolant is constantly flowing through the radiator and therefore only ever gets up to temperature when in traffic, at which point the temperature gauge rises and the fan will come on as expected The car has had a new thermostat however from reading online it seems that the issue is with the thermostat housing, does this sound correct? I can get a new thermostat housing (which includes the thermostat and temp sensor) or would I be better off just getting a second hand one and buying a new seal? Also I was going to have a go at replacing it myself, where can I find out what the correct torque figures are? Many thanks in advance
Having got my polo on the road it's losing coolant from the connections for the hoses at the base of the rad, and where that hose connects to the thermostat housing. I thought it was because of an old hose but I replaced it (along with the jubilee clips holding them on) and it's now leaking more! (Worse in cold weather I assume due to contraction) I read up and apparently the spring clips are better than jubilee (even though they're a pain to put on) but having now put the spring clips back on its still leaky. Any advice? The spring clips were old so maybe I should get new ones if so where from? Is there a magic third option to jubilee clips and the spring ones? And is there a reliable place to get rubber hosing from (what's the right diameter?). Thanks everyone Edit: forgot to mention I replaced the thermostat and housing when I was doing the hose
