Hi All, Sadly I need to fit a new thermostat in my camper, and I’m told it’s a pig of a job. Does anyone have any do’s and do not’s that could help me . Many Thanks, Jerry

When I did the one on one of ours I started by soaking the bolts and threads where possible with plus gas about a week before hand , and I made sure the engine was up to running temp before starting the actual job ( obviously I let it cool after it had been up to temp so a safe level so I didn’t burn my self )the heat helps and made sure all the tools fitted the bolts tightly and correctly .
You must be gentle but firm , the two bolts into the thermostat housing from the water pump are the biggest worry
Make sure you have a new set of baskets ready and clean everything really well if and when you are ready to reassemble

It’s not such a terrible job if you don’t break anything .

I’m sure there is a video on youtube all about what happens if you do snap the bolts or kill the thread , search "jackbox water pump “

What make you think the thermostat is broken?
Squirt some plus gas or similar penetrating fluid on the bolts and leave overnight. Make sure the thermostat is put in the right way round. Should be an easy job, fingers crossed. Afterwards follow the correct bleeding routine.

If those long bolts do snap don't despair. It happened to me but they can be drilled out without too much mither.

Thanks all for your help. In theory, it’s a doddle but everyone I speak to says it’s a pain in the bum job
I will take all advice given and hope all goes well. Starting next weekend, weather permitting
Regards, Jerry

If you have not done it yet; put some copper grease on the bolt threads before you put them back in, then next time they’ll undo much easier.
