Ethank012 Posted August 3, 2018 Share Posted August 3, 2018 So I was on holiday in Wales yesterday, anyway going up a large hill I hear a pop and my temp gauge starts to rise, and I start to loose power! To the point where if I try and pull away I stall, my throttle response also is extremely slow. so I pull over and I have literally no coolant left and my pressure cap has actually popped off! bit weird but I always carry enough water to fill it back up, so I do, all air bubbles out and a quick check I can’t see any leaks. So I carry on going, trucks running st the correct temp but just seams a bit sluggish (more so than usual) but temp starts to rise again. Pull over and put in more water that it’s used! Anyway I limp it to a motor factors that has a head gasket quick seal stuff, about 8 miles up the road, but I have lost almost all my coolant! It’s important that I mention that there is no smoke at all, anyway the head gasket sealant seems to stop me from loosing water, and I managed to drive the 160 miles back home on it with no problems at all, just slightly down on power! When I get back in I saw that a puddle was forming about an hour after getting back in! I didn’t think it was leaking in Wales but maybe I was wrong! Also I have noticed before that there is clearly pink staining on the metal part of the pipe where it’s leaked from the same place before! (I’ve only had the truck about 2 months) I’ve been racking my mind trying to work out why I’m down on power, and the only thing I can think off is that I’ve blown my head gasket, and pressureised the system to cause the leak from the a pipe. Which would be probably where I’m loosing coolant from without smoke! Anyone got any other ideas? What’s the go to thing? thanks a lot!

BogMonster Posted August 4, 2018 Share Posted August 4, 2018 What vehicle and what engine? If a 200/300Tdi then I would say you've probably blown head gasket but if you got to the point it started to tighten up then I would be surprised if there is not damage. Head needs to come off and inspect the head for warping and the bores for damage in my view. Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted August 5, 2018 Share Posted August 5, 2018 Not a popped header tank is it? The plastic ones are known to rupture along the join, and can "re-seal" when the pressure's off. Quote Link to comment Share on other sites More sharing options...
