bushwhacker Posted December 18, 2017 Share Posted December 18, 2017 Hi. Has anyone been able to fab/fit in a heater blower to replace the defender one that is expensive to replace. Does the def one come apart. Would the bilge blower talked about on here do as a replacement ? Any help would be appreciated. Quote Link to comment Share on other sites More sharing options...

Ex Member Posted December 19, 2017 Share Posted December 19, 2017 They are not very expensive. https://www.lrdirect.com/RTC4200-Heater-Motor-and-Rotor-S390-110-To/ Quote Link to comment Share on other sites More sharing options...
DC_ Posted December 19, 2017 Share Posted December 19, 2017 Is it the fan/blower that’s not working or the fact you don’t have heat? My 110 blower works great (said it now), I’ve put a winter blanket/ leather cover on the grill to stop the cold air getting to the rad, the difference in heat coming out the fan is well worth it. 😊👍🔥 Quote Link to comment Share on other sites More sharing options...
landroversforever Posted December 19, 2017 Share Posted December 19, 2017 The defender fan shifts a lot of air. So if its not putting out much then theres a leak in the system. I know when I stripped my truck down the heater to bulkhead seal was knackered. They'll also not blow much if the heater cables aren't adjusted right. The latter also applies to heat if the engine is getting hot enough but no hot air. Quote Link to comment Share on other sites More sharing options...

I know you're up in Scotland with the associated colder weather but my 200tdi used to warm up in a few miles even when it was -7/-8C.

Warms up (Luke warm) without blanket but with the blanket on in about zero degrees, it’s better. If it’s not too cold +2, I don’t have it down. 👍 can’t always check the Thermo I guess just to make sure. Quote Link to comment Share on other sites More sharing options...
landroversforever Posted December 19, 2017 Share Posted December 19, 2017 Make sure the stat is a decent branded one then. Colleague had given up with his until I got him a Waxstat one (I think via allmakes) and it was perfect after that up to temperature in no time at all. 1 Quote Link to comment Share on other sites More sharing options...

FridgeFreezer Posted December 19, 2017 Share Posted December 19, 2017 I know Miketomcat actually un-seized a Defender heater blower that was solid due to mud but that's a rare case and he's special like that. If you're getting power to the fan and air blowing out in reasonable volume then a lack of heat is either flap adjustment, crudded up heater core or lack of hot water from the engine.

western Posted December 19, 2017 Share Posted December 19, 2017 If Sir would care to search the Defender forum for 'feeling cold in your truck' or our vast tech archive for 'defender heater checks' he will find my post on how to adjust the control cables on the heater controls/air flaps, the Sir will be toasty warm. also make sure the new stat is a 88 degree version. 1 1 Quote Link to comment Share on other sites More sharing options...
Paddy Posted December 19, 2017 Share Posted December 19, 2017 I agree with the consensus, my 1991 2.5 truck chucks out more than enough heat. Do the checks above and you’ll be roasty toasty once the engines warms up. Quote Link to comment Share on other sites More sharing options...
bushwhacker Posted December 19, 2017 Author Share Posted December 19, 2017 Yea, seen your write up western and I will definitely be using it to set up the levers and flaps on the heater. 1 Quote Link to comment Share on other sites More sharing options...
DC_ Posted December 19, 2017 Share Posted December 19, 2017 Looking at thermostats, the parts list a 82 degree or a 74 degree. 🎅 Quote Link to comment Share on other sites More sharing options...

Howitzer Posted December 20, 2017 Share Posted December 20, 2017 Does anyone have the part numbers to the small clamps which grip the cables at the heater box end? Mine just fell apart and the right ones would be nice before I adjust the flaps. Dave! Quote Link to comment Share on other sites More sharing options...

western Posted December 20, 2017 Share Posted December 20, 2017 74 & 82 were also used on the olderdisel engines. but all Tdi should have the 88 degree stat fitted. Quote Link to comment Share on other sites More sharing options...

Or hotter: engine efficiency improves with increasing heat: if your radiator pressure-cap is working correctly and you're running at least 33% glycol in your coolant (which raises the boiling-point significantly above the usual 100 degrees) there are definite benefits from a bulk-coolant temperature in the 95-105 Centigrade range. Same goes for oil temperature: in my last job I was involved in provisioning big [think 500-Kilowatt] Diesels to power Internet data-centres if there was a power outage. Mr. Caterpillar was quite happy for the bulk oil temperature to run at 130 Centigrade with the engine being loaded to 85% of its rated output. They ran for 5000 hours between oil-changes. That's half a year of near-wide-open-throttle. Hot engines are healthy engines. Quote Link to comment Share on other sites More sharing options...
