Stuck defender TD5 sump plug

I went to change oil today and found out that the sump plug is absolutely solid, i decided to stop and consult rather than keep on going until something failed, has anyone got any tips to increase my chances of getting it loose without damaging the sump threads etc, The plug itself is still in good order, not rounded off etc, I had a look at previous posts but was not confident about attempting them, hammer and chisel was popular but could be dodgy with an alloy sump

Did mine today and it was stuck solid, good socket and a bit of help from a tapping stick and it freed ok.

breaker bar and a good socket.

Put some heat on it

Use a 6 point socket (hexagonal) rather than a 12 point one and you will have less chance of rounding the bolt head.

or if you have rounded it off smash on a socket with a hammer in 6pt and then break it off

They're always tight on td5s
Need a good strong arm and a good socket then it should come undone

fook sake my missus undid mine she wanted to learn so let her do the service. That reminds me she has to do it again shortly

…………….yes……………………………."service"

at the mo m8 happy days

Massive breaker bar, if that fails massive breaker bar with a extension of scaffold pole, if that fails breaker bar and a HAMMER! Don't think i would wanna heat a sump plug to much

Snigger

Breaker bar and gradual pressure

Six point socket and a breaker bar.
Can also use an oil extractor through the dip stick hole
