v70 thermostat/water impeller

[Dariono4no1]

how much would a garage charge to fix a thermostat or water impeller? I am pretty sure its one of these things that's making my car overheat and I don't want my pants pulled down over the price

A stat used to be about 10 quid and 1/2hr to swap

If by the impeller you mean the water pump impeller, it might be quite expensive as it is driven by the cambelt.

Hello, There aren't too many examples of where year, mileage and trim level could be more helpful.

Earlier thermostats were easily changed at the elbow. "They'd" probably rape you to the tune of 50 quid.
I do not know if the later diesels used the combined 'stat & sensor' as did the petrols.

If your engine is due for a timing belt get, it done. Including the pulleys and water pump at that time is the economical way to go.

Here's the possible kicker. Your cooling system MIGHT be neglected to the point where the heavily rusted inwards of your engine cannot transfer heat effectively, resulting in higher operating temperatures.

If that is the case be sure to get your system chemically flushed.
Also, depending on the age of the vehicle, it might be time to replace the hoses.
They're better than those of yesteryear but do not last forever.

You are nowhere near the realm of despairing; so don't. Kira

years 2002 and up, the thermostat can be quite a hassle to replace, part is around $100. the power steering pump must be put on a side, then I suggest splitting open the thermostat housing and replace only the upper half of the housing. This way, it's about 1h30 job.

For the non turbo engine, it looks like this

You can check if the thermostat opens properly: when the temperature gauge is at normal operating temp, the upper radiator hose should get hot.

For the water pump, the timing belt must be released (not necessarily replaced if it's not due) and the pump can be removed after the coolant was drained. If I'm not wrong, it can be done in about 1h-1H30.

Personally, having been in similar situation, I would never refit a used timing belt as once the tension is released and reapplied it tends to weaken the glass fibre reinforcing stands. False economy not to fit a new one when you've got it all in pieces and also means it wont be needed to be done again for 90,000 miles

I live in barry south wales, uk its a 51 plate so 2001 and its done about 120,000, iam pretty clueless when it comes to repairs and I didn't want a garage taking advantage

Water pumps are extremely reliable. Sticking stat is far more likely. What symptoms have you got exactly. Start from cold and see does the top hose to the rad get hot as the needle comes up to the middle. If you have a diesel this can take a long time.
Just checked your other thread. What is the needle doing when you get a high engine temp message?

[harveys]

Just a thought is the cabin heater still working ,gives out hot air when set to high.
If so good chance it's the stat and it's very easy to test it when it's removed from the car just place it in some boiling water near 90 degree it should open.

ECP have Circoli thermostats that fit V70 for £4.50, I like this design better than the original which has a rubber diaphragm which disintegrated, pieces are probably still inside the coolant system. Changing it on petrol V70 is quick and easy but Volvo made a batch of faulty brackets on P2 D5s putting the access hole in the wrong place making it neccessary to remove the power steering mounting bracket and aux belt. I replaced the allen head screws on mine with standard bolts so I can access them with an open ended spanner without having to remove the auxilliary bracket.
