5 Hours To Do Aux Heater

[marinabrid]

oh yes hereas a brief run down for anyone going to do the job. it seems that some have it easy, i done two now and both taken 3-5 hours.

unscrew exhaust bolt ,, shears off

then exhausts falls from heater unit, needs welding back on

4 :blink: bolts holding bracket to body, 2 sheard off

upper and lower mounting cage bracket bolts both sheard off.

air inlet pipe totally fell apart.

cant do job without reMoving unit, far easier to remove water pipes and take out

very little water loss, just clamp em or bend and tie wrap

clamped water hoses and removed the unit

all top screws to fan rusted away , had to hacksaw em off.

all four body bolts to get to glow plug rusted away

two allen bolts had to drill out

got inside swop plug re aaemble

tested old glow plug and it burnt red, have i wasted me time!!!!!!!!!!!

put new one in anyway.

drill out cage bolts to put new ones in

put back together

started at 11.45am finished at 4.45pm three tea breaks 5 mins each

did job at local bus garage , any tool on hand.

pity any poor sod doing job outside with few tools

hear endeth the lesson. BEWARE, IT NOT EASY.

VW/SEAT recommend bleeding coolant circuit again if pipes are removed at the water heater by iteratively

1. raising front of car by approx 50 cm

2. topping up coolant

3. lowering car again and doing test drive 'til engine reaches normal operating temp

 

until coolant circuit is free of air bubbles...
