Bongo Fury

Hi Guys

got in the bongo this morning drove about a mile, and the engine fan came on about 300yards after that the heater gage
went right across over to the hot so i stopped turned the engine off and left it to cool after cooling down i got it to a garage
where they drained the cooling system flushed it through then they did a pressure test and a vacume test they used some sort of
camera checking hoses and god knows what else. they found that the radiator was all coroded down one side they said this could be the reason for water leak. having only had the bongo 7 weeks i rang Ian Taylor at stoke who got me a brand radiator which is being fitted tomorrow fantastic after care service or what. but my problem is that the guys at the garage who did my pressure & vacume test said it could be something else as well a radiator problems. but when i explained to ian taylor he it was just the sensor on the header tank that caused the engine fan to come even if you've only lost quarter of an inch of water the sensor switch will kick in.
anybody any other ideas

cheers all

Just get the new rad and coolant in and bled up to start with then check your coolant level daily for a couple of weeks then weekly there after. If ther's summat else wrong it'll soon come to light, the info on the fan kicking in is correct buddy and has probably saved more than a few engines my fan cut in whilst in italy due to my van losing coolant very slowly due to a slight head gasket leak back in june, tis all sorted now via warranty

Don't understand that about sensor in the header tank.....has it been bled ??
Shouldn't this be in the Tech Section ???

i think he is saying that if the fan sensor is dry then it puts the fans on

Sounds like to to me..... lets be honest there are only really 2 times the engine fans comeon during normal use..... 1) when the engine is really working hard (like climbing or loaded or both) plus you will see the temp climb if you have a Mason/Modded or TM2 gauge and 2) if there is a "dry" water chamber in the head causing super heated steam......
