TT350 Posted March 17, 2018 Posted March 17, 2018 Hi. So, I've been to the garage so many times now with overheating. Basically, the heaters don't blow hot air unless I'm at 3krpms or over and in traffic, it overheats quite quickly. The garage is painfully slow at doing anything. It'll take him a fortnight to even get round to it, meanwhile, I can't get to work. He says there's no ait trapped, no leaks, thermostat was replaced, fans are ok and he says the water pump is part of the engine so can't fail. Coolant level is fine. What's going on? I wish most of you technical guys weren't down south and could take a look!! Quote
ZMANALEX Posted March 17, 2018 Posted March 17, 2018 Firstly the water pump is mechanical and chain driven and can fail and can be replaced. Back flush the heater matrix and the radiator and then bleed properly. I would guess that you may have a blockage or more likely an air lock. If your tech guy tells you that the water pump is part of the engine and can not fail, then I would not believe a word that he says about the other stuff. See below for bleed procedure: 1 Quote

See below for bleed procedure: I agree on all points and an air lock seems most likely these things are a pig to bleed Quote
TT350 Posted March 18, 2018 Author Posted March 18, 2018 Sorted it today. I didn't follow the guide more, used intuition and patience. Used the bleed valve and just watched the coolant after pouring it in and seemingly looking full but then after a minute it suddenly dropped. Did this quite a few times and 5L of coolant/water mixture later it finally stayed full. No air bubbles. Unfortunately because of the TT conversion, I cant find the reservoir lol which may have made it easier. Anyway I'm surprised the garage couldn't get on top of this issue. Took me 30 mins. Quote

EzeePzee Posted March 18, 2018 Posted March 18, 2018 So my TT has a special cooling setup with an extra Carbing coolant reservoir at the highest point of the engine - ie by the firewall. Previous owner clearly had the same problem as you after TT conversion as lots of paperwork about bleeding/overheating issues but since this has been installed it’s perfect. I’ll dig out a diagram for you. Quote
TT350 Posted March 18, 2018 Author Posted March 18, 2018 Nice. How did you get it to fit? There's literally no space in my bay. Quote
EzeePzee Posted March 18, 2018 Posted March 18, 2018 (edited) An old photo of the engine bay. Blue samco hoses run to the extra tank at the back. (Also an oil catch can at front) Edited March 18, 2018 by EzeePzee Quote
ZMANALEX Posted March 18, 2018 Posted March 18, 2018 Header to the rear and reservoir to the front R/H. Quote
TT350 Posted March 18, 2018 Author Posted March 18, 2018 I've no room there where you've got yours. Mine has a fuel pressure gauge set up there. Quote
ZMANALEX Posted March 19, 2018 Posted March 19, 2018 You will just have to find a corner somewhere and fabricate a mounting bracket. It is hardly rocket science. Quote
TT350 Posted March 20, 2018 Author Posted March 20, 2018 It took ages and a lot of head scratching to fit the catch tank. I have no tools to fabricate things. Quote

ATTAK Z Posted March 20, 2018 Posted March 20, 2018 What tools are needed to fabricate a simple bracket ? Hacksaw ? Hammer ? Vice ? Drill ? about 20 quids worth or have I missed something out ? Quote
TT350 Posted March 21, 2018 Author Posted March 21, 2018 Lol some people just aren't that adventurous with this kind of automotive thing. Give me a house and I can renovate it top to bottom. Anyway, I found it mounted inside the wing. It's fixed and holding. Thanks guys. Quote
